Pulled the carby off and gave it a clean, checked the air cleaner, which was non existant, so motor would have been dusted I'm thinking, it doesn't have a lot of compression, with a make ship air cleaner I took it for a ride around the MX track here at home and it s a bloody good thing, goes alright even with a tied engine, everything else seems pretty good, forks shock brakes clutch gearbox chain and sprockets bearings, fresh engine and an air cleaner and all should be good, oh and a tail light lense....
