After 5 years and thousands of dollars and who knows how many man hours or utterings of the word 'fuck' in any and all of its incarnations I have finished my opus. 73 cb750k Motor bored to 849cc, high compression pistons, hot cam, hd springs, fully rebuilt head with mild port and polish. Lots of other tricks and whistles including koso gauge, Tec shocks, custom seat, modern electronics, drag bars, bobbed fender, black pearl base coat with titanium pearl mid coat, lots of flat black powdercoating and even some plasti dip. Took it for a ride today. Motor is too much, clutch slips above 3/4 throttle. Front brake caliper needs rebuilt.
