well 2 days ago i was riding and i got to the top of a steep hill an noticed the bowl was over flowing so i tore it apart and fixed the float. i managed to foul the plug so i put a new one in and the motor now has 10 hours on it. after all my heat cycles after break-in it ran great now it bogs when you stab it to full throttle and the plugs come out looking black. should i step down a few sizes in mains? also i noticed my base gaskests are leaky would that be another reason?

Your base gasket leaking is not good to say the least. Fix all intake leaks and base gasket leaks before jetting changes.

ok now i need some serious help here tuning wise :eek: according to the esr site i should be running 360- 400 main, a 25 pilot and the needle on the 3rd clip. first off how do i get the needle off the slide to set the clip. second i had a top end port job on my old cylinder now im on stock cylinder stock bore. it ran good with the old cylinder just didn't fit my needs. anyways my pilot is a 55 and my main is a 320. it starts up runs and just wants to die.. plugs come out looking black after opening it up letting it idle the plug looks wet not oily.. should i buy 150-160 main jet and a 25-30 pilot? the esr site jetting guide is for pipe and air box eliminator. please help me!!!
