Hi retro7, the parts aren't really that rare. Can get them at FJT or BS. Of course some of the rarer stuff gotta order (just like any other bikes). It's the bike tat's rare. Good luck with your search!
Yeah. William is right. Domestic models from Japan are usually restricted to 180km/h. At least mine is. The important part for me is not going above that speed. Just that i would be interested to release more power than available currently if there's any to start with...
