wonder if anybody would know why my bike (after running perfect yesterday) would all of a sudden have problems restarting whenever I shut down after riding? the motor turns over but all i get is raw fuel coming out the pipes. If I let the bike sit for about 20 min. it will start back up again, I'v cleaned the plugs, and bypassed the sensor for the kickstand. but am still having problems. Any help or guesses as to what I can look at next would be appreciated thanks
