So Im new here, and new to 2 strokes. I am a heavy equipment mechanic by trade so I know a decent amount about diesel and gas engines, but almost nothing about 2 strokes. So I just bought a pretty clean 2004 blaster from a buddy for 400 bucks. It only has 30 psi of compression. It has the oil injection bypassed and his kids ran strait gas in it. I know the top end is toast, but what do you think about the bottom end? Im not sure what would be damaged first, the crank or the top end. I bought a chinese cylinder, a wiseco piston kit, carb rebuild kit, and a new air filter. I know the chinese cylinders are crap and need some work, but I just want to get it up and running. I have bigger plans down the road and didnt want to put the money into boring the stock cylinder right now. Thoughts and opinions?
