I've finally found the time to begin my complete restoration of my 1972 CB750 K2.
It was purchased new by my father, driven until 1989 and then let sit outside for close to 25 years. My intentions are to restore it to factory condition to use as my daily driver/road tripper.
I also own a 2000 GS500E and 1981 Yamaha Virago 750 however I will be selling both of these to make space (spare change) for this restoration project.
This weekend allowed me to pull the bike out of the garage and begin the strip down. After removing a part I replaced the bolts in their positions to make it easier to bag and tag later. Currently, then engine has a frozen piston, in the upcoming weekend I will be using a mixture of ATF/Acetone as recommended by a few users on the board here to hopefully help free up the cylinders before I remove the engine from the frame.
First steps are going to be pulling the frame apart, blasting it and sending it off for powder coating. I've also been in touch with a vapor blaster here in the states that said he was more than willing to take on my 750 engine and crank case to get that factory fresh look out of the aluminum. I'm really looking forward to that step.
Here are a few pictures of the initial tear down. My goal is to have this bike mostly restored by Late July/Early August, I know that may be ambitious but if I don't set a goal for it, I will never get it completed.
I've pulled out the entire wiring harness except for the wires running through the handle bars to the tree. That will be completed this weekend as well. Any opinions on the quality of the wiring harnesses sold by PartsNMore?
I also want to replace all engine screws with hardened hex heads, any ideas or resources from someone that has done something similar? Any disadvantages to doing something like this?
Also just received my "My CB750 Book" which has already proven to be an invaluable resource combined with the Shop Manual.
Wish me luck folks, I look forward to working with all of you.
