originally i had a 26mm mikuni copy i have now put on a 29mm mikuni and when i put the choke into the fully closed position the bike idles ok then decreases and dies
when i open it it starts to rev to death does anyone have any idea why because automatically i assumed too big a main jet but put in a smaller and all stayed the same and when i try to get the bike to idle normally it revs very little and dies any ideas or is the carb just too big for the bike ?
