I finally found a fairly clean 74 Honda 360 which I have been scouring the earth to find (my father had one when I was a youngin). I want to strip it down to the frame and give it a good scrub, paint, etc. What parts/fluids should I replace/revive while I have it broken down to ensure I don't have to take it apart again in the short term. Thanks.

Go to HondaTwins.net. There are a lot of people on there that will guide you.

All the fluids plus remove the clutch cover and clean out the centrifugal oil filter on the end of the crank---supposed to be done every 6,000 or yearly but because you have to take the cover off rarely gets done so the cam seizes

Here's what I did to a '74 CB360 a few years back.
Not exactly a restoration, though.

click on it !

As its a 74 check into if it has the updated camchain tensioner. Threads on it here.

Thanks for all the information, I have it stripped down to the frame, motor, and wheels now. I'm going to take the remaining parts off the frame this week and paint, clean, etc. to build it back up. The WD-40 and aluminum foil method to remove rust off of chrome has turned out to be quite good advice. I also tore apart and rebuilt the carbs and found a leaking diaphragm. That will cost me $90 unless anyone knows a place to get them cheaper than the Honda dealership or bikebandit.com.

-I plan to take pics of the rebuild for future reference and to post.

Gerhed, that is crazy. I have to respect your ingenuity to come up with that design.

I just posed in another thread about scotchkote electrical coating.

gerhed, that is the best use of a 360 i have ever put my eyes on. Please o please post some more pics.

Just a heads up on the 360 motor. I had a few of them in my late teens, most of them donor bikes for the CL i loved at the time.
There was an issue i found with the cam and the chain. I cant remember what it was, but at around 15,000 mi the cam would start to cut into the motor. Someone at my dads shop told me how to fix it but i never thought much about it. I was using it mostly for a trail bike to go fishing.
You might want to look around for information and see if i'm right.
Good luck

I have heard that as long as you adjust the cam chain tension frequently, you can divert this issue for some time. Does anyone know if there is truth to this claim?

bryanj · « **Reply #11 on:** November 25, 2009, 06:59:17 AM »

Only reason for failure, apart from lack of servicing at correct intervals, was not cleaning the centrifugal oil filter.

There was a baby Honda car that had a very similar engine in it, at least here in UK there was

The machine went through a few redos.
The black was the last.
In '92 I left it in a barn up near Rochester, N.Y.
I fear the engine may be stuck now!
Please note 19" Carlisle flat track front tires.

Sweet job man. How hard do you have to work to turn it. What did you use for linkage.
You will have to get that running once more. I would love to see in action.
Take care and happy Turkey day.

Try www.hondapartsnation.com They are usually about 20% cheaper than everyone else. It'll still probably be around $70 but that is definitely better than $90.

Here she is to date. I'm waiting on brake pads, carb diaphragm and rebuild kit, fork seals, gas tank lock, and some exhaust gaskets.

cbrace0012 · « **Reply #16 on:** November 29, 2009, 02:54:40 PM »

I stripped it down to the frame; painted the engine with duplicolor engine enamel, painted the frame with rustoleum gloss black, scrubbed the heck out of all the chrome with various chemicals, tin foil, and chrome polish, the wiring harness has some "upgrades" and suprisingly all the lights are working properly. I coated the underside of the tank and fenders with line-x. The wheels and forks were painted with duplicolor wheel paint. All bolts/nuts were sanded and painted clear to protect the chrome from flash rust and installed with tape. All the miscellaneous parts (i.e. battery box, tool box, taillight bracket, etc.) were also painted with rustoleum gloss black. My bathtub and kitchen sinks look like a psychedelic mess of overspray, grease, gasoline, and paint thinner. The joy of restoration in a downtown apartmet.

The motor after it was painted.

I really like the duplicolor wheel paint on the forks, this paint is very smooth. Probably the cleanest paint I've ever sprayed not through a gun.

cbrace0012 · « **Reply #20 on:** December 08, 2009, 11:07:10 AM »

Well I got it all put back together but I am having issues with the tank and getting fuel to the carbs. I made this auxillary fuel tank to try and fire it up while I'm cleaning and POR-15'ing my tank.

Sorry about the dark picture, I'll take better ones this weekend.

Haha, yeah, I will get better pics up once I get it all put back together again. I'm waiting on a POR-15 kit now.

She is up and running. I have a few odds and ends to take care of (clutch adjustment, dolling up exhaust, fixing a rear taillight bracket) but I put 28 miles on it in the city this weekend which is about 4 hours of riding. I had 4 different groups of people stop and check it out, ask questions, or take pictures.

Looks great!

cb650 · « **Reply #26 on:** December 21, 2009, 03:34:48 PM »

Yes Very nice. I like that you used diff exhaust too. The originals where just to big. Upset the balance of the bike. Rode mine 100 miles today with the new G/F.

cbrace0012 · « **Reply #27 on:** December 22, 2009, 06:10:15 AM »

Thanks all. I thought the stock mufflers were a little long as well and they had 3" of rot out at the end, so I just cut them off. I was going to make a baffle for them but the part of the baffle that wasn't cut off resembled what I was planning to make anyways. It sounds pretty good so I'm going to leave it as is after grinding down the edge a little. 100 miles is a nice ride, I wish I could hit the open road feasibly.

cb650 · « **Reply #28 on:** December 22, 2009, 04:23:57 PM »

Thankfully mine are in great shape. Just not on the bike.
