I'm thinking of picking up a cheap, small dirt bike for the wife and I to screw around on. Might get two. I found a Baja 150 with a broken kick start spring. I know many think Baja is a POS but I can't afford a great bike right now, and I know a guy with one and it's actually not too bad, and he hasn't had issues getting some parts. I'm new to dirt bikes, not sure what's involved in replacing a kick start spring. Any ideas on how involved it is? I googled it and some people say complete tear down of the engine...
