So my Gs450 I got started the other day and it was smoking alot out of the crank case breather. I thought that mabe the rings were gone as it only had 65pis in one cylinder before I started it, also after running it for 20 odd minutes, the oil light came on. So I stopped it and left it over night. This morning I took the rocket cover off and checked the oil flow to the valves and did another compression test. Now the cyclinder has 140psi.
So my question is what would be causingthis smoking out of the crank case. Is it normal for old engine to smoke alot or is there somthing else I should check?

Cheers

Stuck rings from siting would be my guess - GSX suzukis do seem to breath abit from the breather at the best of times.
