Chris Jones dropped off his very tired 91 883 Sportster and said, something is wrong with my bike, it's losing power. Well, that's because he melted down his front piston. Perfect he said, I always wanted to do the 1200 conversion anyway. Well, the black cylinder heads without machined fins, the Mikuni HRS 42mm carb, the single fire coil and Dyna 2000i ignition in front of a set of Andrews N4 cams can only mean one thing, Chis' 883 got the Buell Thunderstorm high performance 1200 conversion. This is a combination we've done many times and the results are definitely worth the price of admission for sure, it makes power!
