I have got a 83 Xt 200. I got the bike in pieces and put it together from the engine up. I put a carb kit in it I replaced a broken pick up coil and it still back fires. I have gone through two clutch baskets and do not want to wreck a third. I kick the motor over it runs for a second maybe and than dies, I try to kick it over again and it back fires and breakes the starter gear off of the clutch basket. Yes the timing is right on. Does any one have parts for one of these ? any help would be great.
