So I'm helping a friend work on his x22, which I know is the least desirable x bike. I am wondering what all can be done to wake that 4 stroke up. I'll be pulling it apart before long to ensure no piston scoring or anything. The wiring was a mess that I already fixed up, carb has been cleaned well and the bike runs. It does need a new battery and I'll be rerunning the wiring to make it more manageable. There were 2 body welds that are being rewelded and the frame will be braced a little better. Thanks for any advice in advance.
