After decades of riding bicycles I got the throttle fever last winter. Started with a KTM two-stroke that I’ve been having fun riding off-road. A friend of mine put a bug in my ear with his old CB restoration projects. And before I knew it, I ended up with this 1975 CL360. Engine seems to be in good shape. Tank and seat are in great shape. Missing some parts, but my buddy assured me it’s doable to get it running again. So we shall see!
First trip to the salvage yard. Kickstarter. Cool scrambler bars off an SL from the early ‘70s. A shift lever that needed to get bent right. Easy enough.
Left controls and new clutch lever blade installed! Had to make the wiring hole a little bigger since I was fitting four cables through while the old SL setup only had two. This bit did the charm we did a bit of string and rubbing alcohol for lube. Had to break off the set pin on the control as well because the bars didn’t have a hole for it. Routing the wiring under the control was a bit of a mystery at first but I figured out how it was supposed to naturally fit.
Electrical adventures this weekend. Bike didn’t come with a regulator, so I just got the combo reg/rec to upgrade the charging. Easy enough to set it up once I figured out the wiring diagram. I did waste a fair bit of time puzzling over the harness, trying to figure out the wiring mod recommended by Common Motor to connect the two wires coming off the stator. I’ll save that one for later I guess.
New flasher relay was a quick fix as well.
Up front, I replaced the rubber bumpers for the bar clamp, although I was disappointed that they still felt a bit wiggly. Oh well, they were inexpensive.
There is normally a bit of movement in the rubber insulators. They're there to help reduce vibration so if they were harder/stiffer, they wouldn't do as good a job. And as far as any parts you need like the rec/reg combo, there are many sources for good quality parts - just ask an opinion here before buying the first listing you see, often there's a significant difference in price. Take a look at this to get an idea of what else is out there.
No bad reviews, but if you're like most of us here you want to shop around for the best component for the price. Did you look at the link I gave you above?
Common is a good place to shop for ideas, then google around for deals. Heck even Dime City is cheaper some times. One of my favorite places is 4into1.com They sell all kinds of goodies for all types of bikes not just 4 cylinders.
Either way, the mod for the 2 wires coming off the stator is a moot point really, they are connected once the lights are on with 360s, not just when the high beams are on like older bikes.
Took some time off over the holidays to spend time with the in-laws. Back at it over the weekend with a new toy, a multimeter. Went through all of the wires in the harness to better understand the electronics. Not very photogenic but quite satisfying.
Very successful trip to the salvage yard yesterday. Got a seat latch, which I gutted to just open with a screwdriver. Picked up a complete rear brake pedal to fit with the low pipes. Also found a housing for the ignition key. Wiring the bars with a new start button is still a work in progress...
Front brake is coming along. Rebuilt the master cylinder last night. Scrubbed out the inside with scotch brite, which helped with the corrosion but it’s still a bit stained in there. Also, managed to pop out the caliper piston with compressed air after loosening up the old seal with a heat gun. Thing popped out like a rocket! Hopefully will get it reassembled with a fresh seal and bled in the next few days.
In other news, my carburetor needs a deep, deep cleaning.
Make sure you give the grove for the seal in that caliper a good scrape. The brake fluid gets in behind the seal makes a nasty crusty deposit that makes the piston stick in the first place.
And dear god why did someone use silcon sealer on that poor carb? That's gonna take a while to clean up and out of the passages if it got loose.
Basic fuel tank rehab. Replaced the cap seal, which was unexpectedly annoying. Rebuilt the petcock. I was perplexed by this little o ring though. Seems like it should fit on the nut that joins the petcock to the tank but there wasn’t an old one there and this new one didn’t seem to easily fit on either side. Thoughts?
There should be 2 o-rings on either side of the cupler that is on the petcock, that cupler is there to allow you to adjust how the lever on the petcock faces. It will leak if they are not in place.
Exciting to have the controls and grips installed. Also connected the coils and alternator which strangely had too-short wires to reach each other as is. One of many mysteries I’ve encountered along the way...
Probably because they don't connect together......The alternator connects to the rectifier, regulator, and through them to the battery.....
Your bike has a battery powered ignition...The coils connect to the "kill" switch (Battery positive), points/condensers (Primary winding negatives/grounds) , and sparkplugs (Secondary winding negatives/grounds)......
And, looking at it again, that rubber part that is covering the wire is supposed to be shoved into the fins next to where the wire comes out of the cover, that's the insulator for it.
Yes, it wraps up between the head bolt and the valve adjustment cover next to the breather cover then to the coils. I believe there is supposed to be a cable clamp on that head bolt as well to hold it but looks like it is long gone.
My very generous friend let me soak my carbs in a bucket of cleaner and then run them through his ultrasonic cleaner. These babies haven’t been this clean since they left Japan!
Here’s a surprise. The PO removed the alternator rotor. Can’t imagine why, but it means I’ll be heading back to the scrap yard to try to find one. Seems like there are also options on eBay, but it was an unexpected setback.
It looks good and frankly, that's also a good price AFAIK. It also doesn't look like it's ever been apart, the screws are still staked (original stake marks on the heads and the JIS heads are not damaged as so often happens)
