unpleasntdeath Posted March 26, 2009 Report Share Posted March 26, 2009 Today when I started my shee, I noticed exhaust only came out from one side! The other side sometimes moves or moves really slow, what could be the problem? How can I fix. It just got rebuilt over winter from top to bottom new everything! Also its the left thats fine and the right thats having problems, the plugs are new, new oil, and right mix of gas. Quote Link to comment Share on other sites More sharing options...
F.T.W. Banshee Posted March 26, 2009 Report Share Posted March 26, 2009 I would check the compression and synch the carbs. Quote Link to comment Share on other sites More sharing options...

As well as "The other side sometimes moves or moves really slow, "??? If one piston doesn't move you have serious problems. If your just not getting exhaust out of both silencers equally then it is probably a sync issue. But I think you need to explain yourself a little better to get an accurate diagnoses.

SP Well when I start only exhaust comes from one side, but at times the right side will move for a second, hard to explain. Quote Link to comment Share on other sites More sharing options...

TJScott Posted March 26, 2009 Report Share Posted March 26, 2009 i loled at magz. this could be a number of things. are you sure your fuel lines arent kinked? check them both for good flow. sync your carbs, clean them (jets especially) make sure you are getting spark on that side, and make sure one doesnt just idle higher than the other by checking your idle screws.

locogato11283 Posted March 26, 2009 Report Share Posted March 26, 2009 both pistons will always be moving. sounds like youre not getting fire from one cylinder.. Quote Link to comment Share on other sites More sharing options...
sheerider1026 Posted March 26, 2009 Report Share Posted March 26, 2009 check the compression, then check for fuel and spark.. those 3 things are all the motor needs to run.. peace! Quote Link to comment Share on other sites More sharing options...
Dinner Posted March 26, 2009 Report Share Posted March 26, 2009 As Loco said, it is pretty hard for one piston to be moving up and down and the other staying stationary (unless for some reason there is no connecting rod??). Just like others have said, check your compression and make sure your carb slides are opening together. Next thing would be to make sure that you have good spark. After that, make sure you have a good supply of fuel getting through the carbs, reeds and into the cylinder. Check your fuel lines, jets for clogs and make sure your reeds are functioning properly. If those all check out, check your exhaust for clogs!!! I know from experience on this... My experience: Put my new motor together that I recently had ported, rebuild, head shaved, etc. Had new 33mm PWK's, new intake, new filters, new throttle cable, new plug wires and caps, the list goes on. Got everything back together and went to start it. After multiple kicks, the motor finally fired but only the left cylinder was running. No matter what I did, the right cylinder would only ping and tick every so often. I switched carbs, intake boots, reeds, filters, spark plug wires, everything. After the weekend was over from tearing it all back down and putting it back together. I said to a friend of mine "I wonder if there is something wrong with my pipes?" The next day I took my right side pipe off and look into it.....a fricken mouse nest!!!!! My pipes were laying around all winter while I was doing my rebuild. The little buggers made a nest in my Pro Circuits, once I put it all back together in the spring and went to run it. The exhaust pushed the nest into the very tip of the pipe(where the pipe meets the silencer tube). Talk about back pressure for that cylinder, wouldn't even fire! Cleaned my pipe out, low and behold the engine ran great! Quote Link to comment Share on other sites More sharing options...

Wonder how long I'da been fucking with carbs? SP Quote Link to comment Share on other sites More sharing options...
03bansheeLE Posted March 27, 2009 Report Share Posted March 27, 2009 Ive had this happen on three separate occasions. The first was because the right piston rings were melted into the piston and compression was way down (found all this out later that night). The second time was simply a fouled plug on the right side. The third was the carbs were not in sync, the idle screw lock nut had vibrated loose and the screw loosened off. Check for any obstructions in the exhaust, fuel delivery to the carbs, vacuum leaks, compression check, carb sync, etc. If you take the carbs off to clean them I would go a little further and take off the reeds and boots to peek in the cylinder to see piston/ring condition, same can be done on the exhaust side if you remove the pipes.

dajogejr Posted March 27, 2009 Report Share Posted March 27, 2009 And that's why I hang pipes in the rafters over the winter....LOL. Check the sync on the carbs.... Quote Link to comment Share on other sites More sharing options...
Overboost Posted March 27, 2009 Report Share Posted March 27, 2009 my pipes bounce back and forth in sync then they puff together for a second then back and forth again. repeats this continually. guess its right, runs great. Quote Link to comment Share on other sites More sharing options...
