My dad, my cousin, and I all recently had our banshees modded and rebulit by D&M racing in Arizona. We haven't had a chance to ride yet, so I'm asking people who have done business with them/raced them whats the quality level of their work. I myself didn't have D&M port my banshee I had it done by Kenz, however my dad and cousin did as well as milled head and pistins. We all got lightened fly wheel, adv timing, carb tune, jetting, dyno, a swingarm, and check up. (Just some background info) Any help is appreciated Thanks
