Here is my favorite one to ride, It is stock 650 jugs, ported head, 34mm vm's, stock cams, stock airbox, on a 75 chasis, with 78 xs850 leading axle forks, and red wing hammerhead 14.25 lenggth shocks. the gauges are stock 78 on xs850 mounts, head light and mounts are stock 850. fenders are 71 sl350 polished alluminum, front has 69 sl350 top brace. the exhaust is aftermarket down pipes with supertrapp cans. This bike rolls on avon distenza tires. This is not intended for serious off road riding it was designed for maintained dirt roads as well as street riding and does this very impressivly. I am currently rebuilding a 100% stock 75 b bike, a vintage road racer type 75b bike as a 750 with dunstal fairing, 36mm vm's, own tail section, scott gordon exhaust system. I also am working on a 78 special, hardtail bobber on fzr 1000 forks and wheels, on 180 rear tire, and 130 front, with harley 3,5 bob tanks and dash, tank shift foot clutch (hydrolic). And last xs project is a 81 stock class racebike.
