That's cool to see, my son rides a TTR110. But that bike is so under powered I don't know how well it would work. He has a little Cobra CX50 race bike that has more power than the TTR. Would be cool to see them design a kit for an 85cc 2-stroke instead.
Just put a big bore kit on my TTR110 and big carb / exhaust system.. its going to be a snowbike I have dyno runs before and waiting on a intake manifold Im having built.. I will post results. The first one we built runs great and works good in the snow just didn't dyno it..
