Cylinder stopping at top end

[rrr]

Ok so here is the problem: when I reach top end my clutch side cylinder just stop working and heavy blue smoke comes out of the pipe. I changed my spark plugs and switched my wires and it was still the same cylinder that shut off so I guess my problem is in the carb. I am currently running 360's on the main, 27.5 pilots 1.5 turn out, needle on the second clip strating from the top and my setup is : pro circuit pipes, top end port job and I am running on the stock air box and filter with the snorkel off and stock carbs.

 

This thing rips my arms on one cylinder I wonder how it will do on two

Heavy blue smoke + clutch side cylinder.. sounds like a bad crank seal to me

 

cant make much else of it.. blue smoke == oil

[rrr]

I don't think it's the crank seal because they both work fine until I reach top end, then the clutch side cylinder stops and heavy blue smoke starts to come out off the pipe as if it was not able to burn the gas, the other cylinder works perfectly all through the powerband.

at low end the heavy oil will not be sucked into your cilinder.

i really think the heavy blue smoke is oil.

 

rich or low on fuel will not cause blue smoke especially not heavy blue smoke.

 

Maybe someone else can comeup with a different cause.

 

 

In the mean time.. you could check your oil level in your clutch just to be sure.

Thanks man, I'll check my oil level. If anyone else can think of something say it, I wanna try everything before changing the crank seal.
