This is the kind of thing I live for! Hot Rod Motorcycles of all sorts just make my bits tingle. Some of the gang from ProhibitedGarageCo have decided to tear down an XS650, look into its soul, and squeeze some power out of her. I stole this picture from their blog, hop you guys don’t mind (My PC is dead, all updates are coming from my Wife’s Laptop)
Ok, so maybe sound isn’t everything, but there is something to be said about a great sounding engine, especially in a motorcycle. “What about power??” everyone asks. Well, the stock XS650 engine was good for 105MPH on a perfect day, with just the right straightaway under test conditions. I’d argue that most don’t see that kind of speed nowadays. I have ridden with stock engined XS650’s around me, and they all can testify that their is no comparison to stock once you have a rephased engine in your ride. I have not had the balls to run this thing all out for a top speed test, but I can say that it has seen over 120 MPH and I expect if I could get some time on a legal raceway, 130MPH wouldn’t be hard to reach.
You of course have to modify the camshaft for this to all work as well, I’ve got you covered there too. I can modify any stock cams, Shell Regrinds, Megacycle Regrinds, and XS1 Cams.
