79 CB750K
I though I would share my current 79 CB750K build project. I picked up this bike several months ago from a friend that purchased it from the original owner. She was going to use it as a side car project but found a Yamaha SX that already had a hack. I had my eye on the CB for several months and admired them back in the day but never had the pleasure of owning one. I made an offer, she accepted, and now I have a low mileage CB750. The bike just turned over 9,000 miles and appeared to be in good mechanical order.
I completely disassembled the bike, removing the head set greasing the bearing, swing arm, caliper rebuild, carb cleaning, fork service, etc. Everything was removed, inspected and serviced. I adjusted the valves and cam chain tension, checked the compression and everything is well within factory specs. I fabricated aluminum side panels that will replace the OE panels, had a guy build a nice seat and scored a sweet deal on a new 4-1 Vance and Hines header. Cleaning the carburetors was time consuming as I removed the pressed in idle jets to completely clean the idle circuit. Cleaning the idle circuit is key on the CV style carbs. This allowed me to tune the carbs in nicely for the SX air pods.
I was little disappointed that the clutch slipped on my initial test run. The clutch springs weakened over the years. I ordered a new set of EBC springs and will be installing them soon. I use Rotella non synthetic oil and have had good experiences with Rotella in a verity of motorcycles. I need to install the brake light, side panels and clear coat the gas tank and I should be finished with this project.
