Honda ’72 CB350 K4 – One year later

It was just about a year ago that I took a leap and plunked down a few hundred dollars buying my (at the time) third motorcycle, a 1972 Honda CB350 K4. I had hoped that the acquisition of a “Project Bike” would deflect my interest in replacing my CBR250R with a larger bike.

That winter was ALOT more forgiving and I couldn’t help but to creep out to the garage fairly regularly even just to liberally spray everything with oil, or to turn the key and admire the glow from the instruments and headlight. As the weather improved I took more and more of her to pieces, surprising myself when those pieces went back together properly.

We now know the bike runs (a little rough granted), I’ve rebuilt the carbs, cleaned out the gas tank, replaced the front and rear brakes, tires and tubes, throttle, brake and clutch lines, gas lines and assorted relays, regulators, bulbs, dod-dads and thing-a-mahoosits. I’ve even changed the oil twice.

The remaining to-do items on the whiteboard are largely asthetic – replacement mirrors, carb covers have been obtained where the pitting and rust was too much to overcome. The only vageuly mechanical items are the timing and reinstallation of the chain.

The garage now, at least, smells like a garage should. As soon as the weather improves I hope to get back on the CB350 (although our renos still compete for my time). I’ll be sure to scribble a bit about the headaches involved in getting her safetied and plated.

    Yessir! … this has certainly not been a winter for working in an unheated garage :-(

    That machine is looking pretty slick, and it sounds like you’ve derived considerable satisfaction from working on it. That’s the main thing, eh?

    Good luck dealing with the bureaucrats on the insurance and registration stuff ;-)

    Nah, a little too brisk out, especially considering I’m a lightweight.

    It’s been a good project, and I feel a lot more like a motorcycle owner actually knowing how the bits work AND being able to take care of basic maintenance myself. Rather than having to drag it to the mechnaic every time something goes click when it should go whir, or vice versa.

    Yeah, the administrivia is gonna be a nuisance.

    Well done … it looks like the day I wheeled it new, out of the dealership for the first time, oh those many years back.

    It’s clearly in capable hands.

    Rick, a lot of the credit goes to you. She was in really good shape when I got her from you, and while I’ve sunk a fair amount of elbow grease in at this point this was about as far from a farmers field derelict as you can get.

    If she’d have been in any better shape she wouldn’t have been a project at all.


    Thanks again!

    Smells like a garage should – OH YEAH!!!!!

    Wow has it really been that long since I checked in? Granted I was mostly a lurker.. You probably started riding about when I did. I started on an ex500 that I went on a 4500mile solo trip on in Sept 2012. Tried a 650r last year and now own a Vstrom 1000 that I plan to plunge even further west later this year.

    Those Bonnies are nice! Good choice. I too picked up a project bike a couple years ago (76 Suzuki Re5) but I doubt I’ll get to it. I’ll enjoy looking back at the work you did on the 350!
