Pete I owned a 1976 KH 500 with denko expansion chambers.34mm mikunis.barnett racing clutch and springs.ported and polished. I was just in high school when I had this how did I live?
Like any 2 stroke they are happy up high but I find the larger bikes like the H1 and especially H2 750 have enough torque to still put around town with relative ease. But like anything you need to pick the right to for the job. If you're looking for something to go to the local shops a triple probably isn't your best bet..unless you plan to get there really quickly :)
