Been working on this one for awhile. Thanks to the resources provided by users on this site, It's been mostly hella fun. Until today, I've hit my first wall. The jackshaft. I'm having chain vs sprocket issues. Basically, I'm getting a crash course in gearing. I think the engine sprocket is a 410 chain? rear sprocket is 415 sounds simple, so far not so much. Anywho here's my offering any advise is appreciated. having trouble uploading pictures bear with me, please.
