Well I am a newbie to this board and atv's. I am a sandrail guy but bought a banshee this summer and love it!!I mostly dune it at the silver lake sand dunes but I have had it to Bobs raceway in clarksville MI and also to West Michigan Sand Dragway. It has run a best of 5.04 flat at WMSD but here is a timeslip from a trip to Bobs. The banshee has a lightened frame by tyson, 2-5 tyson override, t5's .020 overbore, stock stroke, +5mm long rod running on race gas with 16 cc domes. Stock carbs bored to 27.5 by me and the engine was also built by me. My buddy ported the exhaust and intake ports and after running a couple months I have now done some transfer porting although it has not yet been back to the track since. So these numbers are with stock transfer timing. I have also added a dynatech and a lockup since the last time I was at the track. Can't wait till next year. By the way it has a plus 6 swinger and 12 paddle haulers with 15/46 gearing. I bought the quad with a broken motor but most of the goodies were already on it.
