2 1/2 pounds to much.

Well, I did my first track day. It was awesome. I did go off the track once. No biggie. I rode it out. Dam lucky. my fault. On the second secession. After the fifth lap. the rear tire just kept sliding out. I exit the track. it was getting to hairy to ride on and didn't want to make it unsafe for the other riders. Got back to the pit. The heat raised the tire pressure. Drop the to 30 pounds and the front to 30 1/2. on the third secession. The PP's were fantastic hit hit the golden spot. Through out the day. The bike felt good. Now. dropping 2 1/2 pounds in the rear and 2 in the front made a big difference. I know this sound a little crazy, but it happen to me today. Can a few pounds reaaly make a big differenc?.

Rain. Whats is this Rain i keep hearing?.

Fsho, i had a good bit of trouble with the PP's till I went 29/r and 31/f....made a big difference, but I still wasnt quite comfortable, but thats due to the poor suspension settings i have now i think. Congrats on your first track day

even 1 will have an effect on traction or wear.

the yardstick is a 20% rise in PSI from cold to hot, i.e. start @ 30 cold and end @ 36 hot.

Glad you had fun out there Mike! I wish I would have made it also...but busy trying to recover from all the spending on the new bike :) Yeah, on the track, any minor change can make a huge difference...from tire pressure to body position to suspension changes....

Also...yup I remember my first trackday and going through the weird feeling of not having my mirrors....very strange...I even hit my signal light a few times :)

Hope to see you out there at the next one...

Its important alright...and even more so on race tires.

On the 190/60 I had a horrible time getting lean angle with 30psi in it. Turn in fast as hell but it would not stay down. Hill suggested 27 psi, tried it and totally different, could not believe that it made that much difference. On the 180 it is not that big of deal, but in the 190 it is.

yes, i couldn't believe a few pounds made a big deal. i know better now. A good tire gauge is a must have tool. I had a 79 cent special. Guamanic, It was a good day to be out there. hope to see you on the next track day.
