Sent from my iPhone using TapatalkCould be sucking in oil through the crank seal on the clutch side. Assuming that is what you mean by right side.

Oil is what makes it smoke. Since your fuel charge first goes into the crankcase before traveling through the transfers into the combustion chamber a worn out set of rings allowing blowby isn't going to make it smoke anymore than usual since your fuel charge in the crankcase has the same oil in it as the fuel charge sent through the transfers into the combustion chamber. THIS IS NOT A 4 STROKE. Oil leaking through a worn or damaged seal on the right side of the clutch cover will add oil to the right side of the crankcase and send it with the fuel charge to the combustion chamber, burning this excess oil with the fuel charge producing smoke. That's a logical cause as opposed to repeating something you've heard somebody else claim but have no way of explaining it.

tmace Posted July 3, 2017 Report Share Posted July 3, 2017 Is it smoke or steam? It could also be as simple as a bad o ring on one side. Quote Link to comment Share on other sites More sharing options...

tmace Posted July 3, 2017 Report Share Posted July 3, 2017 If you're still full of coolant that would also rule out a bad o ring. Quote Link to comment Share on other sites More sharing options...

spurdy Posted July 3, 2017 Report Share Posted July 3, 2017 If it is steam, this could be the case. But smoke is oil. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

If it is coolant your level will obviously drop. You can also smell the difference between coolant and oil.
