Smoke issue. Need help

Recommended Posts

 

New cam chain installed

 

Shims are in spec

 

Did a compression test, spec says it should be around 60 within 5 kicks on a cold start, it's doing around 50 on 6 kicks..bike starts up easy with 2 kicks no problem.

 

Trying to figure out the smoke issue, do I need new rings and a piston? I've done a little research but I want some more advice too, I have a top and bottom end gasket kit on the way.. any suggestions? Thanks guys when I swipe my finger in the exhaust and it's milky black residue is that a dead give away it is piston and rings? I wanna know before me and a buddy tear into this thing haha IMG_0862.JPG

I'm thinking it's time for new piston, rings, and gaskets to be on the safe side. Oil is burning somewhere that's my first assumption.

A a my mistake, I thought you wrote that you've done the piston change. (had just woke up) 

But I would first be sure what's wrong before put in new parts, I don't think the piston itself is the problem but maybe the rings or the valve gasket.

You can measure the rings so you can determine if they are the problem 


Thanks! Im going to buy a new piston anyways just in case, save it for later if not.
