stock 06 350 tm dies at full throttle, cranks up after it sits for a minute. not sure if it is a heat issue. acts like it is starving for fuel. Mabey vapor lock. This is a buddies ride, he is replacing the fuel filter and checking the vent lines for kinks today. any help would be much appreciated.
Sounds like carburetor issues,Start with a new sparkplug,clean the air filter,and remove the carb. for cleaning.It's not that hard,remove the float bowl and blow it out really good with compressed air.
if all that doesn't work it is possible that if the original owner fouled the plugs and never changed them, carbon could have built up on the piston. If so take a VERY light sandpaper and lightly rub the surface. When you put the piston back in make sure the rings are still good and put a little oil on it.
