Ok so I sunk my brothers crf230 in a mudhole a couple months ago and now it has started to put out a blue smoke at all times. The higher the rev, the bluer and more smoke it throws from the pipe. I'm assuming its the piston rings but i'm sure the piston and cylinder are screwed as well so I was wondering what the cheapest fix would be? Any ideas would greatly help. I looked at the bbr big bore kit but have to see locally what a bore honing will cost me. Thanks for any help.
