a couple of months ago i accidently stripped the threads on my crank, and i got that replaced by my mates dad, got it back and the bike did not tick over, you had to constantly rev the tits off it and if you stopped the engine would die, the dynamo was not charging the battery anymore and the bearings had gone, the piston blew on my way home from having it back the 2nd day! so i sent it back to him and i got a new piston and new bearings, it stil wouldnt tick over, and the bikes acceleration was terrible and we saw why my clutch was nackerd! so i changed that with a malossi one and put a standard variator back in because i didnt have the right rollers for my hebo one, one day i was riding home and the bike made a rattle and stopped and wouldnt start unless you put fuel directly into the carb, my air filter was soad in petrol, and my piston had blown again, also there is a vacuum pipe located going into the petrol tank and it is like the valve is stook, you can suck air out if it but not blow air into it, i can not think of why my bike keep blowing pistons and will not tick over, and do i need a new vacuum pipe? i know there is an essay! please give me a hand on this one, i need my bike back! cheers, steve
i think that vacume pump is your fuel pump? and your not meant to be able to blow up it. when you suck on it it should let petrol out. thats what its like on mine anyway if youers is the same. are you running your new pistons in properly?
well on mine there is the fuel pump and underneath is supposably a vacuum pipe that should suck air into it causing the fuel to be kind of blown out of that pipie if you get me? i dont know how to post picutres on here but ill post one as soon as i find out, and the first one that blew was old and the other one was also used, my dad reckons that the rings have been snapped when being put in due to not liing them up properly, cheers mate .steve.
