Some of you say you've ridden dirt bikes before and some still do. I was just wondering if ya know dirt bikes mechanically. I have a old school 1980 Suzuki DS 100cc dirt bike, have had it since I was a kid, the damn thing doesn't start up. It's my fault though, because I never take care of it in the winter time. I usually just take it to the All Bike Centre in Richmond, for them to fix it up. All they do really is clean the carbo., the air filter, and put a new spark plug on it, and charge me like $175ish. If any of ya know how to fix dirt bikes, can ya give me a hand and let me know how I can maybe fix it up myself, and help me save some dough.
