What tire pressure to run???

OK I got a strap for the front and I'm going to try the bike with the front strapped down and the rear preload backed off all the way to get a little more sag. I usually have a little problem with traction but I never really fooled with tire pressures. Whats the best pressure to run in the back? I usually have around 36psi cold before I go down so I'm guessing its gotta be close to 40 when hot, tHanks for any help.

Come on guys! Someone answer the guy! I'm curious as well since I'll be hitting the drag strip for the 1st time tonight.

I would back it down but you are going to have to test differnt tire PSI get it just right. Remember lower tire PSI more contact patch thus more traction. I would start about 5lbs lower then factory specs. This is just me and I know you can drop it lower. But I would bet some guys do not drop tire PSI at all. So go out there and test then give us your results. Last year I went 10 PSI lower on a 600 and it made a big differnce as far as wheel spin off the line. Remember you are walking a fine line between rear tire spinning and you wheeling from too much traction and clutch . Good Luck Jeff

FOr road racing now it depends on weight of rider and tires but around 29-30 psi I would think you might even run less for drag racing.
