There seems to be an awful lot of new engines coming out with 206cc. Any chance the F200 standard will be updated so we don't have to replace the crank?

Full Plastic Bodies vs. CIK Bodywork

T Hinton — Wed, 15 Nov 2006 13:09:23 GMT

Just as the title of the thread implies, Have been wondering about this for awhile.. Here in the West, most karters race with the CIK bodywork like this:

It seems like a lot of the Oval and Sprint classes run these back east:

There are a handful of the lower HP racers (KT-100, Briggs) in this area that run the full aero type bodies with good success but so do the CIK "pod" style of bodywork.. Does anyone here have experience with both that can give some reasons why one might be better than the other and under what circumstances?

Thanks in advance..

Aftermarket part submission? How?

hedlywrkin — Sun, 13 Apr 2008 17:27:22 GMT

Hello, I will have the bugs out of an aftermarket ignition controller that utilizes a stock OEM coil and armature. The unit is capable of either static or three "stage" advance - 0/15/30 for example. What is the process to submit a product for F200 use? And.... What is required to submit an engine, in the same manner as Burris/Yamaha - say Mitsubishi/Me- for F200 use? Thanks.

If you have questions about the New Briggs Flywheel and Igniiton ask here

John Nuttall — Thu, 02 Nov 2006 19:14:32 GMT

I've had some questions from the Briggs guys about the PVL ignition system and new Flywheels. Frankly things change so fast over there I don't keep up.

2006 rule 9.10 Flywheel and Ignition Coil: Aftermarket or OEM flywheels permitted. If OEM flywheel is used it must be unaltered and meet minimum listed weight the stock OEM coil (ignition system) must be used. Approved aftermarket flywheels only may be used. Spec diameter and weight as follows; 6.75” +/ .25”dia. X 4.75 lbs +/ .75 lbs. When using aftermarket flywheels, any approved OEM F200 coil may be used on any engine. (i.e. Briggs coil on a Honda, Tecumseh coil on a Kohler, etc) External coil modifications to facilitate mounting are legal. Coil mounts, flywheel key, spark plug boots and plug wires are non tech items. See below for approved flywheels.

Does the new Briggs flywheel meet the 4.75 lb weight requirement? I don't know.... Weight it before you buy it.

I would assume the PVL Ingition will be approved since it's a OEM coil.

What’s Happening In F200?????

mikeburris — Mon, 01 Jan 2007 18:20:59 GMT

Lot’s of new and exciting things are going on in F200 and 2007 really looksto be a breakout year for the program! I thought I’d start this thread to post updates on existing programs and new ones going into placeso if any of you hear of any others in your area please feel free to add to the mix.

On the oval scene Craig Covington and Matt Frederick of Acadiana Speedway in Cajun country have stepped up and expanded their program with the addition of Junior lll F200. Acadiana started out from scratch a couple of years ago and nowF200's aretheir fastest growing classes!

Out here on the west coast, local sprint club LAKC spear headed by David Jimenez has added an F200 Sr class for 2007 and judging by the turnout last Saturday's practice at their home track, California Speedway, they have a nice size group to get the season started. We have still have quite a few more announcements to make so stay tuned!!

clutch engagement

WrecIt — Sun, 08 Apr 2007 12:15:28 GMT

Ok just like with everything else kart related if you ask a 10 people what your clutch engagement should be you will get 10 difrent answers.

I lost my set up sheet that Jeff Clements sent me on clutch engagement and can not remember for the life of me what he said to set it at. I have a e-mail in to him but thought I would ask around to see what others think.

We were running an MDC with the black (stock) springs. Are planning on switching to red springs this season (for modifyeds) One person told me to set up for between 4500 and 5000. I asked a clutch builder and he said that he does not realy have any experience with F200's but that sounded high to him.

This is for a 1/10 - 1/8 mile bullring with 23 degree banking in the adult class.

Thanks Guys

Titanium Axles

Why are titanium axles not allowed in the BNSS? Is there a safety issue or is it based on performance?

2007 BNSS Rules

BNSS-ADMIN — Mon, 29 Jan 2007 20:31:04 GMT

Attached is a PDF of the 2007 BNSS Rules.

If you focus on Sections 3, 4, 7, 8, 9 &10 you should cover everything. If you see something that isn't clear or out of place please let us know as they will be posted in their final form in about a week.

WF vs F200 help me out guys, no fights or finger pointing

Rich Eisgruber — Tue, 14 Nov 2006 15:37:50 GMT

We have a guy that wants to start a WF class at a local dirt track, hey I'm all for any good racing even if its a briggs OHV, so I suggested letting me run my F200 with them and I would add weight. Rich Domenick made the suggestion that I run a restrictor plate to even the field. Anybody know which would be better or fair, weight or plate? I'm more concerned that I'll go out and wax 'em then I'll be stuck with the weight and the plate

Another F200 Driver in 07

WrecIt — Mon, 28 Aug 2006 23:59:08 GMT

I just wanted to make a post to sort of echo what was written in the post here titled "

Junior lll Hooked On F200 "

My son started racing Jr F200 with Tim and the Goodhope gang but due to several issues we pulled out of Goodhope and went to our home track from last year, Naugle Speedway, just outside of Pittsburgh, Pa.

He is currently running in the Adult F200 class there and has overcome much of the problems that lead us to pull out of Goodhope. Being at Naugles gave him a comfort zone that enabled him to start to run his Kohler F200 the way I knew he could run.

Well this past weekend was an off week at Naugles so we returned to Goodhope with one minor change. Insted of my son running with the Jrs I jumped behind the wheel with the Goodhope F200 Pros. I was a bit nervous to say the least but my son and I agreed that it was time for old dad to find out what exactly he goes thru every week. I did not set any records but ran well enough to have several people comment that I did well for my first time behind the wheel.

This has lead my son and I to talk about adding to our race team. In 2007 KJM Racing will still have Tyler Rector as out "Title" driver but Tyler will have a team mate behind the wheel of a Kohler Mule powered #70 driven by me.

F200 racing is AMAZING!!!!!! I can't wait till next season to be out on the track with my son!!! I am sure that he will be teaching the old man a few things but I am more than ready to learn!!!!

Thanks Burris and tracks in our area like Naugles, Goodhope, and Blanket Hill for suporting F200's.

Cool can

Domenick22 — Thu, 24 Aug 2006 16:00:57 GMT

Saw a plastic can on a car at the car show last week with the fuel line passing through he said he puts dry ice in it to cool the fuel, he said it atomizes the fuel better OK

Doest it make the engine run better, cooler or faster?

Junior lll Hooked On F200

mikeburris — Wed, 12 Jul 2006 19:39:36 GMT

Here is a copy of an email we received over the weekend from one of the Goodhope Junior lll F200 racers. Nancy Waselich (Goodhope owner) put a Junior F200 class together and as you can see it has been well received.

Dear Burris,

Our son, Tim Hanes, races at Goodhope Speedway in New Springfield, OH. We purchased a YF200R1 for him through Nancy, the track owner to try out this year. He is having the time of his life. He has raced the Briggs flathead for four years and now he doesn't even care if he races it. He claims it has no power. He is running the 18mm restrictor and has darn near as much power as the Sr. Pros with no restrictor. He is doing the traveling series with Goodhope to several tracks throughout OH, PA and WV. So many people have commented on the motor and the fact that this class is always so exciting to watch. Turner Motorsports did the build on our engine and was extremely impressed with it also. We are hoping to travel to some of the BNSS races to check out the competition. Around here, we are the only ones running a Junior class. I think that will change soon though. Anyway, we just wanted to say thanks for an awesome motor. I'm sure we will be getting at least one or two more before the end of the year. I'm pretty sure this will be his last year running a Briggs flathead.

Thanks again

The Hanes Family

T n T Racing

The comment "He has raced the Briggs flathead for four years and now he doesn't even care if he races it. He claims it has no power." is great and to be honest with you we hear it ALL the time!

100 miles and not a drop in my catch tank

Domenick22 — Fri, 02 Jun 2006 20:30:19 GMT

We raced the Milwaukee Mile last weekeend and raced over 100 miles and not a drop of oil in our catch tank, I have a 1/2" hose from the valve cover to the catch can this thing breaths.

But the front of our kart is drenched in Kohler barff and Briggs barff, why do these engines push out their oil out?

Are Stud Girdles Legal?

Jamie Webb — Thu, 29 Jun 2006 18:24:52 GMT

The discussion on the "other" forum about head plates, rocker covers, and stud girdles brings up a good point.

John wrote: "Rule 9.12 includes the statement “No
other alterations to original configuration permitted”
Since the head doesn’t have a stud girdle one can’t be
added."

Does that go for ALL the F200 engines? It has been my
understanding from the start that stud girdles were
allowed as the valve train area and parts were
non-tech as long as you did not use an titanium parts.

Here are pics of the ones I use:
http://www.kartingengines.com/girdle1.jpg
http://www.kartingengines.com/girdle2.jpg

http://www.kartingengines.com/girdle3.jpg

If stud girdles are NOT allowed..... I've got a BIG
problem as I have over 40 heads out there right now
with stud girdles on them.

If you could, please let me know as soon as possible.
I have 3 heads on my bench today I'm working on that I
had planned on shipping out tomorrow.

Thanks!!

PCV plate modifications questions

John Nuttall — Wed, 28 Jun 2006 23:08:14 GMT

Review of pcv plate questions from another website. The plate in question use has been modified from a PCV plate to act as stud girdle. The welded on washers act to prevent the rocker studs from moving. Rule 9.12 includes the statement “No other alterations to original configuration permitted” Since the head doesn’t have a stud girdle one can’t be added. The PCV plate is a standard item on the head and is a legal part. The modifications make it illegal because the modifiation change the intend purpose of the plate. The longer rocker studs are OK and the plate with clearance holes for rocker studs would be ok. But modifying the plate to hold the studs is not legal.

Rule 9:12 Valve Train: Push rods, push rod guide plates, retainers, springs, keepers, rocker adjusters, etc, non tech. Steel valves, springs and push rods only. Retainers may be of aluminum or steel. Intake valve diameter, 1.080" maximum, exhaust valve, .990” maximum with a minimum stem diameter of .188” (4.77mm). Stock OEM rocker arms only (with no alterations to their stock ratio). No interchange of rocker arms between engine brands. Stock (Briggs) OEM cylinder head plates only. Rocker arms and (Briggs) cylinder head plates may be welded or reinforced for strength. No other alterations to original configuration permitted. Flat tappets only, must be stock appearing. Unless otherwise specified no titanium components allowed.

The welded on washers are the modications that make this a stud girdle.

Stud "Stiffeners"

Jamie Webb — Sat, 01 Jul 2006 01:06:27 GMT

I know stud girdles are illegal. However, with the stud being non-tech, can additional nuts and/or washers be added to the rocker stud for reinforcment? (no engine in particular, all engines).

Can the stud be replaced with a larger stud or bolt?

Welded Heads in 2007?

Jamie Webb — Tue, 23 May 2006 21:28:39 GMT

I know it's early still in 2006, but I have a question for the 2007 rules. Will welded heads be legal in 2007? What is the buzz? I keep hearing from customers in the upper Northeast a source "in the know" is spreading word welded heads will not be legal in 2007.

Thanks!

Best Clutch for F200 engine?

jimbo26 — Sun, 19 Mar 2006 15:31:26 GMT

I am just finishing building an F200 spec engine and was wondering what clutch do people recommend? It is a full senior spec engine.

Air filter question

Rich Eisgruber — Tue, 28 Mar 2006 09:19:06 GMT

Is anybody doing anything with their air filters other than using an outerwears cover and or a foam prefilter on the dirt tracks, just curious I figured the filter would get a lot more abuse compared to a flat head being it sticks out the side right by the RR tire

Thanks

F200 electric start

karlznet — Sun, 19 Feb 2006 01:38:13 GMT

BNSS 2006 F200 Rules

BNSS-ADMIN — Fri, 03 Feb 2006 19:23:45 GMT

Attached is a copy of the preliminary 2006 F200 Rules. Note that there has been several minor changes and additions none of which should effect on any current engine legality. Please post any questions or comments on this thread for us to review as this will be finalized next week and posted along with the complete 2006 BNSS Rules.

F200 Updates and Changes for 2006

BNSS-ADMIN — Tue, 27 Dec 2005 15:35:43 GMT

Here is a list of updates and changes for the 2006 F200 engine rules. As you can see they are minor and should not affect any current engines in the field. If you have any questions or comments please post them below.

Add “valve stems shall be a minimum of 5 mm (.196) in diameter.” This would be added to Rule 9.12 and is intended to limit the size of valve stems for reliability and cost purposes.
Add ARC Models #6613 W/F Flywheel (w/ring gear), #6614 Animal Flywheel and #6614K Kohler Flywheel to the approved list in Rule 9.20.
Add the following to Rule 9.8. “All three rings must be present in the grooves.”
Change sentence 9.12 to read “Stock OEM rocker arms (with no alterations to their stock ratio) only. No interchange of rocker arms between engines. Stock (Briggs) cylinder head plates only. Rocker arms and (Briggs) cylinder head plates may be welded or reinforced for strength” The cylinder head plate callout was inadvertently dropped from the specs in 2004 and reinstated because of numerous inquiries about a legal configuration.
Add to Rule 9.11. Cylinder head repair. Each Engine will be allowed an approved area on the intake and exhaust tracts for external repair of broken through “thin cross sections” while porting if deemed necessary. The area shall be no greater than a .5” (1/2”) square and either welding or epoxy is acceptable. This matter was submitted to the various approved engine suppliers in late 2004 for consideration and to date the only “official” response has been from Yamaha. At this time the only approved repair is for the YF200 R1 intake port in the area shown in the photo. The final wording may change and others will be added as necessary.

Memo Gidley and Secrets of Speed on F200’s

BNSS-ADMIN — Fri, 13 May 2005 17:46:48 GMT

Memo Gidley and Jeff Grist have put together another great book in their “Memo Gidley’s Secrets of Speed” series entitled “Four Cycle Kart Racing”. Click on this link (http://www.mgspeedsecrets.com/F200/) to get the low down on Yamaha’s new YF200 R1 kart engine. The rest of the book is chock full of articles on set ups and driving and in my opinion is one of the most factual and relevant books to date on these subjects. The book deals mainly with sprint racing but many of the tips and suggestions in Secrets of Speed carry over to oval racing and bring up a lot of ideas and tips that are not common knowledge in that group.

Needed Part numbers for the differant Engines

hensley1 — Sun, 20 Nov 2005 12:55:24 GMT

I am wanting to build all the types of engines except the Yahama (got one )and a briggs ,,,,
NEEDING the part numbers and so forth
kolher what's the engine code for a dual bearing steel bore and so on
Tec,,,whats that one as well
Has i see it this is one of the things that is lacking in this series.

I started the theads on Bob's Site as well

Anyway if a guy is wanting to work on a Honda and wants to make sure he is buying a dual bearing steel bore or if he wants a cool bore to put a LA Sleeve in one
well i think most of you get the point .....its like going to Sm*Eng* warehouse if anyone has got a better way lets here it

JUST post the codes and helpful info thanks
mainly it is the block code and telling you if its a

dual bearing and steel and an alumiunm bore

IN short these numbers need to be POSTED to help the sport ............
Here is another point in hand a head cost 32 buck for a briggs f-200 a W/F head is 130 buck get my point if we can get all the numbers up everybody save HARD CORE CASH Just ONE more reason to FLY F-200..........

Burris Camp is there a way that you all could post each engine part numbers on here leave it at that Where a new guy could pull up a set of part numbers and go from there

I know this interfears with the yamaha sells but as a series and F-200 Format it would help the new builders.......

Make it where know one can change the numbers and so on if there is a problem i am sure some one will let you know LOL.....

Thanks jh for got to type at the start of each build type put the build sheet that way it is always at the top or first to look at for veiwing

F200's in the Southeast

mikeburris — Wed, 16 Nov 2005 15:32:42 GMT

We have received many calls inquiring about the F200 class that ran the South Carolina Burris Winter Nationals at Sunshine Raceway on Nov. 12th. People were amazed with the power and reliability and according to Cooter and Rowdy Jordan every time they went on the track spectators lined the fences! The F200's also ran with the Animal Limiteds and made a respectable showing with one of them (Roger Padgett on an F200 for the first time) finishing a 3rd behind the winner.

Rowdy sent me an email on what a show they put on and here is a quote from it;

"I was truly impressed with the F200. That was the first time I had seen one on the track, and WOW! The trick will again be getting these guys down here to understand the benefits of such a program."

From the response we have received so far it looks like they already see the benefits.

Great job. Thanks to all you guys who made the trip and supported the SCBWN Series.

Thanks To The F200...

Zablocki — Wed, 11 May 2005 18:05:19 GMT

thank you burris for giving me the opportunity to run a motor class such as the F200. as you may know we have made the jump to 305 sprint cars and since we ran the F200 almost all year last year, the transision to the higher horsepower was faily smooth. most people were telling me that it would be ATLEAST 3 to 4 weeks before my right foot would be able to find the floor bord. my first night out i missed the feature by one spot in both the heat and the B-main (spun in the B while in a transfer spot... oops) and i still managed to have smoke pouting off the rr tire i was so hard on the gas. after that night, i had a good idea of what i was doing and was able to manage throtle control, yet another skill i learned while running the F200 and came from 17th in the B-main (broke in the heat race) finished 4th and transfered to the 'A' and got up to 12th from 20th before the motor decided to go sour on me and i pulled off so i wouldnt be "in the way".

compairing myself to other karters that have advanced this year, also to 305's, one of which was one of the top racers in the state, all but one rookie besides myself has yet to make the features (the top karter i was refering to has not). i personaly atribute my success to the throtle control and adaptation of the higher hp, that of the F200 class.

now if only this sprint car was as simple to maintain as the F200 i would be even more happy

again, Thanks

Burris Wheel and tires....

racinondirt — Tue, 26 Apr 2005 20:20:35 GMT

Ok, switching to the narrow wheel setup on my kart with F200 engine. I know this setup doesn't use the high cross setup like the flat heads class does, so help!! What is a good setup for numbers with the narrow wheels? Air pressures also and what is a good temp range on the 33's? I know the forum changed and there was a discussion about percentages to use, but their gone now. Give me some ideas for senior class at 360#.... thanks..

Yamaha F200 vs. Animal F200 (and other engines)

Mike Burrell — Tue, 26 Apr 2005 20:21:06 GMT

Anybody have any thoughts or experience with the Aninmal (in F200 configuration) vs. the Yamaha YF-200? Opinions on which engine would be best for sprint racing?
