    Default Negative's of dropping you tire pressure?

    Sorry guys if this is a really newbie question, but up here in Northern michigan its starting to cool off a lot and most of the events at the local track by me are in the afternoon/night, where it has been getting to the high 60's low 70's. I have been running around 15-18psi in the rear and it hasnt been hooking very well. if i go lower than that maybe around 10psi while im at the track does running that low hurt my mph or time at the track?

    yes to both et and mph, but so does spinning tire. lower till you get traction. try different tire or how much you heat it up.

    Its an 07 GSXR 600, wb is right at 62", lowered 2 1/2" front and back, not sure the hp but its -2+2, bmc filter and jardine pipe. It didnt break lose completely last time i was there (keep in mind it was only about 58 degreese) but it just didnt grab until about 200 feet to go (1/8th mile track) i think next time if its that cold ill try to heat it up a lot more and see where that takes me. bc there isnt anyway my bike shold have the power to do that and if it was breaking lose completly i could blame it on myself.. im gonna go back sunday and see how it is, hopefully its warmer

    There's no way I would lower the tire pressure that much on a 600. If it doesnt hook at 14-15psi, then adjust your launch technique.

    If you are convience you have a good hooking tire, suspension is the next place to look. You can have the best tire out and still not hook if your suspension itn't right.

    I cut consistent 1.4 60s at 60'' on my 600RR with a shinko hook-up @ 25 psi. Adjust suspension and get that tire hot.

    adjust your suspension.tighten up your rebound,loosen up your spring,soften up compression(some of these or all of these can be applied) & adjust your launch &do a longer burn out.do not get water on your front tire because your rear tire will spin right through it when launch.drive around the water box & then back your rear tire into it.spin it just to get a little wet ,pull up some then do your burn out,stage in the groove (good laid down rubber or traction compound,& try to stay in it during your run).leave with a little less RPM's while slipping your clutch out a little more.trial & error.you will get it.pratice.get somebody at your home track that understands suspension dynamics to help you out.

    Like the rest of the guys have stated start with the suspension and work on your launch I run a the same tire at 20psi on my busa and its 68'' and my bike hooks but as mentioned those two pieces of the puzzle when perfected will get you right ******* can second that statement about my bike he knows me however I have tried the hookup but I have a street bike so that didn't. Pan out to good eat the tire up fast so never tried that again
