Like I said scope it and you will know. I wouldn't waste my time on any other test. No matter how many times you blow the oil out the results won't change. Sadly don't ask me how I know

What brand are they Scott?

feel for you... let us say so far it is not a ring nor a piston just some blow-by till the borescope is inserted between the ... and a look see tell the story

Hoping the best man, be a shame to have to tear that bike down.

Just spoke to @Neville Lush - issue identified as wrong oil viscosity (too thin) and wrong breather filter Nev spotted this from the pics i posted - the Bloke in the tin shed knows his stuff - so simple.
Upon further investigation it appears who ever did the modification in Melbourne had taken the cam chain tensioner out to paint and the chain slipped a couple of teeth and bent the valves etc. This was fixed although the cylinders had become glazed as a result (spent 3 days trying to start it- constantly flooding with fuel) then the bike sat for three or so years before i got it and flooded the engine every time i tried to start it - this has over time damaged the oil rings (A little) adding a bit extra crank case pressure and hence the oil. This company also appears to have installed a dodgy breather filter that looks like an oil filter from a 125cc for stroke motor.
Any way hears some pics of the cylinders.
Thanks for you feedback

I've been following this thread with interest and have been hoping it was something left of centre.
Nice pics of the inside, what did you use?

have a good weekend mate!

I bought the shorter one in the smaller box as the cable has some rigidness to it.

CP pistons glad you got it sorted out and glad I was wrong. Next time i'll keep my mouth shut and wait for Nev to respond first.
