I bought this bike as a joke many years ago thinking it would be fun to see how long it would hold up to my very abusive riding habits. I replaced exh. and rejetted it, stiffened up forks with 20w oil, put on some serious off road rubber and stuck to a regular maint. schedule; other than that this bike has been abused from day one with absolutely no mercy. 13800 mi. later it still runs good. I am amazed at what this thing will do if you push it hard. It will overheat quickly when bogged down in mud though (exh. glowing cherry red many times)so put water wetter in it. This heavy ugly looking bike is as tough as an army tank- don´t be afraid to run the hell out of it because it WILL take it!!
