The motor is new never, never run It was built for Me as a race motor
By Mike Hallam in Canada. Mike is one of the most respected and Competitive racers in dist.2 The liner has been flowed ,the head has been shied ,That's all I can tell you. Sorry for my poor choice of words. It Has been modified I have bought my share of back markers over the years, take your chances TGFALCON
