how can that be if Andrew Lee went in tons faster? extra speed might have been the immediate cause, but reducing it is not the solution since we are talking about racing. unless u are at lap-record pace, theres always room to go faster with the proper skills and equipment.

1yr on a set of forks won't make them perform noticeably different, esp if you have a set of aftermarket carts. they keep the oil really clean. and 1yr isnt enough time to make the oil break down or anything in a set of forks.

going up in front tire pressure can be a good way to reduce chatter. it also can help the bike turn better, esp when hard on the brakes. the drawback to this is that slow experts and novices might have a hard time getting the front tire hot enough w/ a higher pressure. but u didnt say u went up in pressure.

its possible that your front tire was too worn to hold that higher pace, but I doubt it. it goes without saying that someone could have gone faster on your front tire. how many sessions/days did it have on it?

The change was down in pressure. I had been trying to stay close to settings that I got from the bridgestone guy and adjusting by about half a psi or so, but I kept losing pressure (meaning that it would be about 1/2 pound lower when i got off the track). So I dropped it like 3 psi, and that made a big difference.

My forks are just stock with race tech valving. This is still my first track bike, I've never actually ridden a bike with "good" suspension, so I have no idea how good they ought to be.

No one passed me at Riverside in that session, I think it was the previous session and they went by on the front straight (i was just guessing that it was Andrew Lee, but now that I have thought about it, it was probably Chris Siglin). My weakest point has always been accelerating out of corners.

I'm not saying that I went into riverside faster than anyone could, I'm saying that I went in faster than I could.

I think if i find myself in that situation again, I will try to run wide first and decelerate second.

thats bad, thats real bad. it both suggests u arent getting any heat into the front tire and/or u are losing a TON of air. rem, the pressure should be higher when u get off track - at least 3psi higher for almost everyone. u probably shouldnt have ridden the bike like that.

Ignorance is bliss.:laughing

I must mention that I used the woodcraft warmers on the hot setting, I don't recall the numbers now, but the temp was not all that much less than the temp they recommended for just off the track. I don't think it was leaking, because it would go back to the same pressure after being on the warmers.

oh I read your prev post wrong, thinking u had a leak. sry.

ya, u prob aren't getting enough heat into the tire. u just gotta brake harder and later for all the braking corners.

def keep an eye on your front tire pressure off the track. u can probably stick with your -3psi setting for now so that u actually get a rise. but as u get faster, ull likely want to bump that back up. although, that assumes the pressure the rep gave u is what all the fast people use.
