I just replied to another thread about wheels and, as a few of you know, I build wheels. Part of the reason I build wheels is becuse I felt that it was sort of an under addressed componant of m/b's. The very 1st thing I noticed about the kits is the shicruditty sprocket mount. It wasn't very long after that when I broke my hub and was done w/ "rubber donut sprocket mounts". This key componant really made my bike reliable! When I built my bike I'd read up and I have a fair amt of fabricating, mechanical, and motorcycle experience. So I replaced the ign wire, plug and cap, the studs and structural hardware, loctited/nyloc'd everything, and port matched the intake and exhaust. I also bypassed the whole kit chain and tensioner using bicycle chain. I check all the time and all that ever comes loose is the front screw on my rear fender. It starts up every time, it doesn't leave me stranded, it's reliable! What makes your bike reliable?
