And i got same engine in my pit bike that ive had 2 week (second hand tho) and second gear just gone yesterday,like my buds pit bike thats same engine and hes second gears gone,my cousins with same engine aswell.But on cousins bike 3rd gear went.But we dont ride these like wimps,we f**king smash them all over the fields for few hours on weekends.
Just take it easy with the gears when you get your cart going.And can you not use like a rear sprocket off a 90cc 4 stroke china kids quad as the use same type engine.
Have you bolted the engine down with the 4 bolts that should bolt the foot pegs on engine when the engines sat in a pitbike.hope you no what i mean
