well i finally got my bike back from getting the kawi intake cam, thin headgasket, and port and polished head. i also degrred the cam 104/105 and put new plugs in. i had a 16 front and 42 rear setup..... my first couple passes were terrible. i couldnt get better than a 9.90.... my last ten i was runnin 9.40s-9.50s. then i changed to the 15 front. the track was cold and wasnt prepped. i kept spinning. i made 3 complete passes. i ran a 9.7, 9.5, and then a 9.3. plus i couldnt get better than a 1.59 60 ft on my bike, i rode my old bike and cut a 1.43.... after the 9.30 pass, i had to give my friend his front sprocket back.... the bike isnt tuned and it was the first time ever at the track on that bike, plus i havent rode a bike since last sept.. sooo,,, i am going to order a 15 front this week,, tune the bike on u4 and try it again... im looking for an 8.90 pass..
