Yeah they are, they can help you with any of your over the counter parts and oil, however mikes port work does not compare. I had him do the cylinders on my big bore motor. I thought it was the most bad ass thing around. Then I started running in to guys who had work from Kurtz, HJR, Fast, Passion, R*Z, A&S, and WildCard. Yeah....... No comparison. Mike hasn't done R&D on banshee stuff since he was making those viper sleeves. Cool idea, but the idea was 10 years to late and that was ten years ago. Mono jugs moved in and mike made money fixing banshees and other Atv/PWC, not building and R&Ding banshees like the site sponsors here. I like Mike and Kim a lot, and the big mike guy at the counter is awesome. But there is about another 4/5 sets of newer hands around and they are fucking jabronies. I dumped my bike off for dyno tuning. They handed it back to me with one wet plug and one white plug. The intake was hanging off and no body knew why one cylinder only needed a 48 while the other wanted a 55. Really?! Haven't been there unless I'm in a pinch and need something that day.
