So I picked up two used raptor 80s for my kids. One rides perfect. The other just started blowing grey smoke. We went on a trail ride today for a few hours and it smokes like a champ. Then i see oil coming out of the muffler. Im guessing its the rings allowing the oil to pass causing the oil in the exhaust. Any opinions? Would it be better to replace the piston and rings or the whole motor itself?

oil burns mostly white ish looking, but its really "blue"

grey or black is from a rich feul mixture. i would try and get a cheap stock cylinder and keep it an 80 i hate big bores. they are nothing but problems.

and just so everyone here doesnt flip on me cuz i know how most forums are


THIS IS JUST MY OPINION!!! as is everything that comes out of my mouth/keyboard....idk why it has to be said
