Last year I had boughten another cyclender and planned on having some work done on it this summer. Looks like my plans have been moved foward. Might get the cylender bored 2 over just to get alittle more compression out of it. Either way this little adventure hurt the wallet. I did how ever get to see the power of a bore and port job. Not real noticeable until riding with other kids it was cool to call him up front of the pack and see that he had the power to pull away from the kids pack.
