hi having problem with this bike,starts and revs ok but it doesn't pull.replaced electronic ignition and coil cleaned and rejetted carb.the cluch is ok but as soon as I release cluch and give it sum gas it bogs down.had a replate and piston kit not long since.anyone got any ideas on how to fix please.
have you checked the fuel tap? does it function as it should. this sounds like a fuel problem. starvation or flooding, check the condition of spark plugs sootied up or
pale.
