I was looking at those twister motors, but I didnt know much about them or found any reviews on them besides BigRed350x. So after speaking with Andy at M&M Atv on the phone I knew the Serval was what I was looking for. Which is a 80hp bike on Pump Fuel, I have Shearer Pipes and 33mm PWK carbs, and all the other supporting mods already. I am very happy with the purchase and excited to recieve the kit when it comes. So I wouldn't say FAIL (BigRed350x), I would say WIN,WIN,WIN :headbang:
