When roll starting my 1997 Suzuki 80 dirt bike bogs down and the engine won't turn is this a carburetor problem ie compression or a piston problem?
Get the compreesion spec, then aquire a compression leak down
kit. Test compression, make sure it is in or close to spec. If
compression is fine, try an NGK BR series plug, and clean then
adjust the carb to spec. If the engine does not fire, check for
spark and fuel flow. If the engine still does not fire, take it to
a service pro. If all above systems are fine, then you should have
it running in no time.
