So if i am right the avenger 85 is just phantom 85 without the problematic jug ?

Golly G Damien, that's a lot of work reading all that. Can you just tell me please?
For the matter of record. Yes the yd85 bottom end is both av85 and p85. The reason the av85 was known for crank seal issue is because of a production specific to early avengers being assembled at yd (yuandong). Or so I am to understand.
Short version- both sit atop the same yd100 case with yd85 crank
 
It did actually. The case height from the crank is within the same tolerances, meaning it won't effect port timing much, if at all.
If the the phantom piston is on it yes. However the p85 and av85 have very different crown heights. The p85 being closer to the domed 110cc. Thank you uncle Damien. That may have been unclear.

It was the second question I marked in red that needed that clarification and Mike caught it knowing what I was asking...lol...I knew he would know...lol.

I've become acustom to uncle Damiens meticulous nature. Somewhat from understanding his reasoning. Although it may take alittle searching. This forum is 1 of if not THE MOST referenced place online for new comers looking for answers and to solve issues. That being the case. The more specific the better and always best to try and put things in the clearest and most detailed way possible. A person of less than average intelligence such as myself maybe be the reader OR a person in search of a difficult question to answer. Best to be clear,detailed and try to use terms the layman can easily digest.
