Pulling barrel and pistons , a Utube recommendation?

Don't open it up until you perform the proper tests.

Park it for a week. If there is a puddle under it, its a drip.

Have someone follow you and either decelerate from high speed in gear or role down a hill at speed with the throttle closed. If it smokes its rings.

If it smokes only on start up, its valve guides. Or possibly an electrical fire if Ken has rebuilt your starter.

I did that, a mate behind me mentioned it , back off down a long hill then a big puff at the bottom as I take off.

The smoke shows up as you again open the throttle? It doesn't smoke as the speed slows down with the throttle off?

If those two conditions are met, then I would take a good look at the valves and guides. Have you performed a leak down test?

The shop I'll take the barrels to will seat the valves for me if they need it. He's a keen motor cyclist, ex racer and Ducati enthusiast and very decent bloke .
