I just sent you a PM with all my contact info.
Send me a txt so I can add you to the contact
list on my phone! :thumbsup::thumbsup::thumbsup:

I have 10" 5 lug Douglas Wheels that came off my KBS Mk 5 that I want to sell.
I have 3 Fronts and 2 Rears (see photo) if you need extra wheels and they fit your car. I also
had one 5 lug KBS front...

That's an orginal KBS front suspension. Those are the orginal KBS front uprights. The Invader front uprights are different. If you talk to Mike Quadrini tell him you have and orginal KBS front...

Call Mike Quadrini!

Go for it.

Where on the crank do you want to hook something up? You can't remove or modify the recoil per the rules!

Also keep in mind if you have a mobile external starter that's not onboard the car you...

The Drive Clutch is the existing Clutch that's mounted to the engine. If that existing Drive Clutch is drill & tapped to accept the Starter Gear then you only need the gear that mounts on the back of...

Yes. they have Electic Starters which is what you want if your going to road race the car. You need a Clutch with a Starter Gear, the Starter, & the Mounting Bracket. The pull start recoil has to...

I don't understand how all these Vintage Groups work or how they're organized? The guy that started this thread races a Vintage FF maybe he can help us get more F500's approved for Vintage Racing.
...

The Wheelbase should be measured. I purchased a KBS Mk3 that I thought was a 73" WB by looking at it.
It was 80" when I measured it.

For information on the Phantom chassis I would contact Mark Volbrecht his user name on this Forum is Mark 21.

I'm pretty sure all the F500 cars that were at Homestead were 600cc Motorcycle cars....

Mark is working to get older 500cc powered F500 cars eligible for Vintage. Personally, I would like to see F500 eligible in the SVRA National Organization so F500 can go to the Vintage National...

To answer your question! Your car has a roll bar that meets the current GCR rule it can be road raced with a Rotax 494 engine in the F500 Club Racing Class. Last year there were 5 Rotax 494 powered...

“Some say that if you hold him in the wrong way he doesn’t work properly, and that just very recently he developed an irrational hatred of Rubens Barrichello. All we know is he’s called the...

I'm going to go race and work on making my car faster!

Constantly bringing this splitting the class up and or an Ad Hoc Committee effects participation IMO!!! People sit back and don't participate because they think the class is going to split and...

The class cannot be split and remain a National Level class. Any proposal to split the class has been rejected by SCCA multiple times over the last four years. If your sitting around waiting for the...

I’ve already taken the initiative and spent 8 months trying to get performance adjustments approved when I couldn’t race last year. I have to much work to do now and I’m not taking on anymore....

Thanks, Clint for your cordial response. I meet you at Mid-Ohio in 2015 you were also very cordial to me then and answered all my questions. I’m not trying to question anyone’s driving skill,...

IMO getting any performance adjustment approved is difficult.

Reality is SCCA has rejected all of these proposals MULTIPLE TIMES!!!

No 494/493 car/driver can possibly win that's been argued for the last six years so why do we now need a pipe rule. Pipes are open and have been for the 593 powered cars for the last six years. I do...

I said 775lbs minimum weight not 750lbs. You may not need the weight reduction if you can get enough power increase from the 159 Degree Rotary Valve & the bigger Carbs. You still need to add AERO...

F500 is a Restricted Class, it's not a Spec Class. The class restrictions need to be open enough to allow racers to build cars that are competitive within that set of class restrictions. If racers...

Please see my PM!!!

This proposal makes no changes to any Rotax 593 or 600cc MC cars at the front of the pack!!!

If there’s no Rotax 494/493 car/driver combination that can win if these changes are made then...

1) Allow the 502 159-Degree Rotary Valve in all 494 Engines

2) Allow 40mm Carbs in the 494/493 Engines (was not in my first proposal)

3) Reduce Minimum Weight to 775lbs. in the 494/493 Powered...

My last 494/493 proposal (that may need tweeked) makes no changes to the current Rotax 593 or 600cc MC engine & weight restrictions. I'm trying to make these changes without putting the 600cc MC...

Clearly you don't understand what I'm saying. Lets try it a different way. The car with the current engine on your Spreadsheet can't be built without changing the rules! No set of numbers exists for...

After further thought and discussion offline. I think I’ll leave all my option open.
I’ll wait and see what decisions SCCA makes this year WRT the F500 class.

"Carpe diem, quam minimum...

Greg:

IMO under the current GCR Engine & Weight Restrictions for a Rotax 494/493 (500cc 2-Stroke) powered car it’s almost impossible to meet this cost criteria in the F500 class. In a...

Thanks, for the clarification and rewrite, it's greatly appreciated!

It's clearly written, figure it out!!!

If your confused, maybe you should go see a Doctor.
Because, I don’t have the proper Degree or Credentials
to be able to help you.

My current racing plans for 2021 are to only race at SCCA Regional Events and spend absolutely none of my money at any SCCA Major Event or attend Runoffs that would contribute to the F500...

Eric, Thanks for your cordial response.

I didn’t make any claims or statements related to the Dyno Results or the 600cc MC engine. I have no interest in discussing or arguing about 600cc...

In 2018, 2019, & 2020 4-5 Rotax 494 powered cars participated in SCCA Major Events. Also 1 Rotax 494 powered car participated in the SCCA 2018, 2019, & 2020 Runoffs. There are almosts no 500cc...

There are Three Rotax 2-Stoke Engines in the F500 class

1) Rotax 494 (Rotary Valve) 2 Stroke Engine - Appox. 105Hp
2) Rotax 493 (Reed Valve) 2-Stroke Engine - Appox. 105Hp
3) Rotax 593 (Reed...

600cc MC Dyno Results

Just so it's clearly posted based on your numbers!

A Pro Built Rotax 593 (600cc 2-Stroke Engine) is getting close to 115Hp!

Any 2-Stoke Rotax 593 car owner can correct these numbers if they...

The Horsepower Number in your Spreadsheet for a 600cc Motorcycle Engine with the current 28mm restrictors seems to be incorrect. I don't own a 600cc MC Engine so I'm not going to post any Hp numbers....

I really have no interest in discussing or arguing costs with anyone inside the F500 class or outside with any of the other open wheel classes in SCCA. The F500 class is a good class! Anything...

If this is the case, then it sounds like this Cost Spreadsheet is a really a set of Survey Results that was based on the subjective opinion of the people who responded to the Survey! What hard data...

Please see your Spreadsheet!!!!

Please explain the Gearbox Rebuild Cost for a F500 2-Stroke Powered car in in cells AK18, AL18, AM18 on your Spreadsheet.
Cell AL18 of your Spreadsheet states...

Too Few!!!

F500 Novakar/Nova Blade Runoffs Winners

2007 – Brian Novak
2014 – Brian Novak
2015 – Calvin Stewart

Who’s the 4th F500 Novakar/Nova Blade Runoffs Winner?

I think he switched to a 593 several years ago, but I may be wrong!!!

I have no more input into the 2-Stroke carburation discussion that was the topic of the previous thread.
So, let me answer these engine questions on a thread with the correct topic, plus people may...
