Well, I rode the CB750K1 today, and shook out some little flaws, the throttle cables both vibrated loose from the linkage mounts, so fixed that... and the start wire kept pulling loose from the connector in the headlight shell... re-routed that... then, I picked up a clutch cable from Pat at the shop, and installed THAT! Now, it's running quite well after setting the dwell at 24.7degrees! All in all, a satisfyingly, cold pre-spring sunny day!
