I recently purchased an 04 crf50 for a few hundy. Bike is absolutely wore out and engine is blow. I'm new to this and need some direction. The bike has been a little modified but still stock ride height but, in very rough shape. Basically everything cosmetic needs be replaced. Question is, do I try to keep it stock as possible or turn it into a pit bike with piranha suspension and engine in mind. I cant seem to capture what these machines are worth so any help would be greatly appreciated.
