Screaming Yellow Zonker Posted April 19, 2007 Report Share Posted April 19, 2007 well it sounds like you have a blown crank seal. The one behind the clutch cover. they are not that hard to change. Quote Link to comment Share on other sites More sharing options...
questionzzz Posted April 19, 2007 Author Report Share Posted April 19, 2007 i see i see.. im also wondering if because of the uneven smoking, could it mean its running stronger off one side.. do u think im losing power?? Quote Link to comment Share on other sites More sharing options...
Screaming Yellow Zonker Posted April 19, 2007 Report Share Posted April 19, 2007 you will have to do a compression test to figure that one out. But what normally happens is the right cylinder will start sucking the trans oil through the seal and cause it to burn more oil on the right side. It is like $8.00 for the seal.

mpbanshee Posted April 19, 2007 Report Share Posted April 19, 2007 Before you go splitting the cases, check out the carbs. You could just be a little rich on one side. Remove the carbs, clean out all the jets and passages, and check the jet sizes (main jet, pilot jet, and neelde clip position). Put it back together, make sure the carbs are synced, and the air screws are set correctly. Check the reed condition while you are at it. Do a few runs, and see if it clears up, and check your plug colors. It could very well be a crank seal, but check out the carbs first. Crank seals are cheap, but you have to split the cases to replace them. Quote Link to comment Share on other sites More sharing options...
fastrthnu Posted April 19, 2007 Report Share Posted April 19, 2007 Mine did that once until I synced the carbs. Quote Link to comment Share on other sites More sharing options...

kojack Posted April 19, 2007 Report Share Posted April 19, 2007 when I replaced my seal I didnt split the case. yes you have to split the case. My buddy had his carbs running to rich on one side and we used the carb sync I got from FAST and dialed them in better. When we finished the heavier smoking on one side had gone away. Is your pipe spitting out oil? I had a crank seal go bad and it would spit oil and ran super thick blue smoke out of the right pipe. Quote Link to comment Share on other sites More sharing options...
jet mech Posted April 19, 2007 Report Share Posted April 19, 2007 I just had this issue with mine and I had a dirty set of pipes and exhaust port, cleared it self out. deffinately check your carbs I say and look into you engine from the exhaust side you may have some build up from tunning it after your build Quote Link to comment Share on other sites More sharing options...

I know that for a fact. some might have to but didn't. I replaced it when a piece of the clutch basket took part of the seal out. this was also 3 years ago.

Screaming Yellow Zonker Posted April 19, 2007 Report Share Posted April 19, 2007 this was just over 3 years ago. I do remember a lip but never loosened any bolts to remove it or install it. I got the seal from either the dealer or Vito's (Vito's is right down the street from me). Part of the clutch basket took part of the case out. the small over hang over the crank. Please excuse me I'm not trying to tell you that you don't have to split the case. I just might have been lucky. Quote Link to comment Share on other sites More sharing options...

Are you sure you arent talking about the seal on the impeller? The two case halves are what hold the crank seals in place. Quote Link to comment Share on other sites More sharing options...

The two case halves are what hold the crank seals in place. I had this same problem not too long ago. Definately check the carbs before splitting the case. On mine it ended up being the throttle slides not matching. One side was sitting up higher than the other. You can adjust it with the adjustment on the throttle cable where they go into the top of the carbs. Quote Link to comment Share on other sites More sharing options...

Please excuse me I'm not trying to tell you that you don't have to split the case. I just might have been lucky. I think you are talking about the clutch side case cover seal. It's not a matter of getting lucky, you MUST split the case in order to replace the crank seal. It's like having hand cuffs on, you can't get your hands free unless you unlock them with a key!
