Well, I started the beast to move it yesterday & noticed smoke out of the exhaust (kind of a greyish colour) and it sticks around for a while (doesn’t quickly dissipate). Checked the plugs & they are black (plug fouling hasn’t ever been a problem with is bike). Did a campression test and getting around 120 psi. I tried pulling the dipstick with engine running…….. mistake. Crankcase seems to be under pressure?

Was probably like it the last time it was used (about 2 weeks ago) just didn’t notice it. Didn’t notice any problems with lost power & starts easily. Checked the oil and it seems normal.

Really hope I am not looking at a top end rebuild. Anybody got any ideas?
