I agree i had a race in Illinois and coming out of the corner i had alot of bounce (i inflated the tires from 13 to 22 psi in the right frontand from 9 to 15 psi in the left front and in the back i inflated both tires from 17 to 26 psi.

After I did this i had minimal wheel hop and i could "power" through the corners alot better.

Keep in mind i used to use an opposed the "torque monster" in my local organization.
sit down, hold on, shut up

Go up to 10 lbs of air in the fronts it will help a lot.

I also had the sme issue my first race this year. Would exit a corner and got a SEE-SAW effect happening. With a "SOFT" front tire it just wanted to be like a rubber band....I incresed the PSI and reduced the bounce quite a bit.

Another thing you should look at as well is your seat location. Get it FORWARD!!! Not sure how much power you have in your engine but my V-TWIN was carrying the front wheels off the ground exiting turn 2 and 4 halfway down stretch! It gets kinda scary when your steering does nothing!!

After looking at a few photo's of me racing I relized that my seat was pretty far back as compared to a few other racers. I moved that seat forward, dropped it down, and now it handles like a slot car!!!

BTW George....you ever get to finish up any spindles yet??? You can ship me a pair keyed for brakes when they are ready!!!

I will definitely try the increase in pressure, that seems like it would cause more bounce! I was thinking I was running to much air! Imagine that, sometimes less is more. George I agree with the front end setup, after seeing yours the one I got is definitely entry level, but for the money it got me racing!!!! I am already trying to put some $$$$ aside to get one of yours!! I was thinking it was bouncing maybe because it was too stiff!

Generally the softer the track (mudy or thick powder) the less air you run in the fronts. Here is what I ran at the race.... L/F 5psi  R/F 7PSI  L/R 3psi  Right rear heat 15psi feature 23psi. IIn the OUTLAW Race and 1 on 1 I had 28 in the right rear. But that didn't help with the wheel offset in an inch...

Thats kinda close to what I was running, I was running 7psi RF and 5psi LF and the same in the rear, the mower was handling fairly well to me but had a terrible bounce on exit ! Now I not talking about the hole coming out of turn 2 good grief that hole would just about make a bull dozer bounce :woo:

Right I agree but with your front end more air should stop or alow the bounce down. The geometery is off and you cannot adjust it so you have to compensate with air.

Do you think I would lie about my pressure's!!!! You apparently do not know me very well... I never ever touch the left rear. Never Ever except to make sure it is at 3 psi.

Trust me I have seen the back of George's mower :mad2: And from the looks of his left rear tire, it might as well be flat!

Think Stagger and how to get it legally when you must run the same size tire and rim on both sides!!!!!
