Might be a dumb novice question, but I'm a dumb novice! What's involved in running an open chain primary like that? Any weird maintenance issues? Thanks, Chip
Not a dumb question. For a dragbike there is not really any maintenance involved beyond lubing the chain the same way you would the rear. For a street bike you need a more constant oil supply. On my chopper it gets it from oil coming past the main bearing. You can also direct the crankcase breather tube to the primary chain. Your clutch rollers need to be regreased occasionally too. I don't really recommend it for the street though. It's just one more source of a oil mess on the bike and on yourself. Kind of nasty unless you don't mind being a dirty buzzard.
The Show & Go Cycle Shop is my private two car garage located in the foothills of Central CA. I am building everything from early Desert Racers - Street or Strip Dragbikes - 1960's Style Show Bikes - to 70's style Radical Choppers. Specializing in Pre-Unit construction 650 & 500 twins and vintage aftermarket parts identification. Buy, Sell, Trade, parts made by Webco, MCM, MCA, Bates, Flanders, Wassell, Superior, Routt's Cycle, etc. Period photos wanted. If you have stuff for sale related to what you see here email me. I will post pics of my projects from time to time and keep an ongoing thread of pictures and old magazine articles featuring modified British Motorcycles from 1946 onwards.

ReplyDeleteThank you sir! I was mostly concerned about the clutch rollers and they're lifespan. Your right though, sounds pretty damn messy!
