well, it looks like about the same time I started asking my questions they got answered.......
I know that the engines I'm looking at may not hold up nearly as good as the GP460 or some of the others but I just thought they might do me pretty good for a while, but actually now that I think about it for an extra $125 the GP460 may not be a bad route to go.......!
Thanks for putting this info. up MotorBicycleRacing
