Here are some pics of my 1982 Honda Nighthawk CB650 and my buddy Jesse's 1982 CM450.
The specs on the cm450: exhaust are fence post, seat is a street sign - hand shaped. Handlebars are scrap electrical conduit, rear fender - trailer fender of course, shaved blinkers. No front fender, wrenches used as fender and exhaust brackets. Rattle can flame job, cut rear springs to lower and cut front fork springs.
On the ''blackhawk'' - cut rear and front springs, rattle can flame and paint, cb900 handle bars cut to fit, electrical conduit custom exhaust, some suzuki parts rear fender and front brakes, pod filters, 1890's glass doorknob for a choke lever, other odds and ends on both bikes......
