jjdillon426 Posted September 26, 2007 Author Report Share Posted September 26, 2007 i was just thinking, i had my timing plate at 4 degrees before the crank install. should i advance it or just leave it? Quote Link to comment Share on other sites More sharing options...
bansheefreak Posted September 26, 2007 Report Share Posted September 26, 2007 it didnt do this before you sent motor out??/ what all did you change??? is this taking off in 2nd gear with 22in tires? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted September 26, 2007 Report Share Posted September 26, 2007 Are you using a spacer plate or cut domes? Did you get the engine port timings redone to match the 4 mil crank? What is your gearing? what gear are you leaving in? Have you tried slipping the clutch instead of dumping it.... There could be a number of things...mechanical OR Rider....

jjdillon426 Posted September 27, 2007 Author Report Share Posted September 27, 2007 it has a spacer, 4mil & 5 longrod, stroker pistons, deck height .042, ports are perfect, 22 tires, 15/41 gears, taking off in second, and no it didn't do it before, but it didn't pull near as hard as it does now if i can get off the line Quote Link to comment Share on other sites More sharing options...
wesw Posted September 27, 2007 Report Share Posted September 27, 2007 if your bike can pull that gearing with wedges in sec it has some power, youmight try like 14-42 43. i used to run that in sec starts with wedges. Quote Link to comment Share on other sites More sharing options...
