PhillipSpearman Posted February 15, 2005 Report Posted February 15, 2005 OK here is the deal. My buddy has an 87 shee. It use to run perfect but one day out of the blue it would not run good once it warmed up. After it warms up and you kill it you have to pull it crank it. It is not hard to kick but it is like you cant kick it fast enough to start it once it is warm. After it warms up it just doesnt run that good, it kinda misses and acts stupid. So far the top end was completely redone. New pistons/bore, new reeds, and all new boots and gaskets. No change... We have swapped plug wries around and I even ran his coil on my bike because it just didnt seem like it had enough fire but it ran fine. It has an after market stator that ohms out good, the pick up ohms out good. The only 2 things that I think that it could be is either the CDI ( hopefully) or blown case seals (which will suck). Has anyone had this problem? What are some of the different signs of blown case seals? Phillip Quote
Leadfoot350 Posted February 15, 2005 Report Posted February 15, 2005 If the left seal is messed up then it will suck in air and lean out that cylinder so do a plug check and if it is the problem then the left plug will be white. If it is the right side it will suck in all the tranny oil and spit it out the exhaust. You can also check for these problems with a leak down tester. Quote
PhillipSpearman Posted February 15, 2005 Author Report Posted February 15, 2005 I will check for that asap. With blown case seals how would the bike run? Quote
itsaripper Posted February 16, 2005 Report Posted February 16, 2005 The seal is not blown out, it is just leaking. If it is just leaking or blown don't run it because that side piston will seize up soon. With the new top end you should have real good compression. Do the leak down test. It will show you where the compression is going. Quote
