just wired up bike...everything there is fine....when my bike fired up it spit,sputtered,backfired and would cut off...and had a terrible time restarting it...grinding and churnin.....

im going to reset floats on carbs as i mite not have done it right the first time...when i use the clear tube method...do i turn the petcock off to keep from refilling the bowls while i adjust the floats? mikuni 38....i forgot to mention that the airbox has been replaced with k&n filters...straight pipes and the proper jests were installed ....this was done by pro street cycles in richmond,va.....ran great all last summer and part of this summer...left carb started flooding out on the way back from lil sturgis in md....but that was due to trash in carbs...has been rectified...

thanx in advance
peace

Yes, shut off fuel and drain bowl before removing.

Jim
