GregGorman Posted May 5, 2009 Report Share Posted May 5, 2009 A good weekend I got a 7th, 9th, 5th, and 7th. I was having a lot of problems with tire wear and getting the bike to finish the turn. I finally made some improvements to both of those and that resulted in my 5th place and my best laptime at PBIR by one second of 1:19.5. First up was the GTO Saturday night race 7th: I ran 6th for most of the race but got passed with two laps to go and just couldn't keep up. From watching this video I noticed I was missing my mid-corner points and worked on that in my next races Next was Unlimited Supersport on Sunday 9th: Personally, this is my favorite video EVER! Takes me back to a video Keith made with Chuck Graves where Chuck passes the enitre Endurance racing field on his sprint bike. The story is we swapped tires and my mechanic forgot to adjust the tire pressure. He literally remembered at the last minute and stopped me from going out on track so he could let the air out. This caused me to miss the warm up lap and I had to start from pit road after all the experts and amateurs made their start. LOTS of passing fun. Then came Unlimited Superbike 5th: The batteries died for the video camera so there's no video. Got a decent start and did my first sub-1:20 lap time. I finally got the bike to turn a bit better and completely handled the massive tire wear problem. I caught 4th place in traffic and almost got him at the line. Finally, Unlimited GP 7th: Seven riders nose to tail for two laps until I make too many mistakes and lose touch. My best lap ever of PBIR at 1:19.5 is on lap two.

Cobie Fair Posted May 5, 2009 Report Share Posted May 5, 2009 Greg--are you having an issue with the bike holding a line? Have you picked up the back of the bike at all? CF Quote Link to comment Share on other sites More sharing options...
GregGorman Posted May 6, 2009 Author Report Share Posted May 6, 2009 Yeah, when I get on the gas it runs wide. There's a lot of grip at this track and it massively tears tires on the right side in one session. I think the grip may be part of the problem. Anyway, I didn't raise the rear, I lowered the front by 5mm. To address the tire wear, I increased the tire pressure on my NTECs to 30psi rear. That still might be a bit low. Next time out I'll try 31 and see what it looks like. Quote Link to comment Share on other sites More sharing options...

It might not yet be high enough in the back, and for sure set up can effect tire wear. I'd give Will and ring in a day or so, he'll be driving across country (hammer down right now loading and fabricating), and Mike P loves to talk about suspension, I think more than girls even.

GregGorman Posted May 6, 2009 Author Report Share Posted May 6, 2009 Yeah, I'll do that. I've got 9 days of talking to them real soon. See you in joyzee. Quote Link to comment Share on other sites More sharing options...
oldboyonrgv Posted May 11, 2009 Report Share Posted May 11, 2009 If its tearing up the tyre, you have a set up problem, sounds like its squatting under power. Quote Link to comment Share on other sites More sharing options...
