I ran 1:20s at putnam on my 07 gsxr 1k with just a slip on and 2cts! I only run 1:18s on my 06 track bike with full suspension and michelin dots! The 2cts are def great tires!
I did the output shaft in my 06 1k....pretty simple doing stuff in the bottom end! Only issue i had was when it broke it shot metal all over my engine and it was a bitch to get it out! Good luck!
Hmm have a pair of black gloves, but the sides of 1 or 2 of the fingers need sewn up! Lmk if your interested and ill snap a pic when i run to my parents house
