Ok for starters I'll take any heat that comes with being a newbie. Maybe I should have searched for a few hours. There's ALOT to search here. I never realized how popular this is. I've searched for a few minutes and I can't find a centrifugal clutch for this little motor(Homelite XL). I want to put it on a mountain bike (eventually without pedals), when I get it reliable. I was going to build a sleeve so I could put a mini bike clutch on it. I've built racecars but I've never done anything like this before. And I should ask is the stock bicycle chain and rear sprocket gonna hold up and will it give me the correct ratio? Thanks in advance for all of your knowledgable input.
