Hello everyone! Welcome to my CB360 Build

Some background info:
I recently purchased a CB360 in relatively decent condition. I was told it was running before I went to pick it up. When the previous owner went to start it, it ran for a few seconds then died. He couldn't get it started again before the crossover fuel line ruptured... More on that later... Also one of the floats were stuck... A huge mess. We waited for the bike to drain then loaded it.

The drive home loosened up the floats and the fuel line was a quick fix. The bike fired up after a few kicks. It ran rough for about 5 minutes then calmed down. After that it would start up on the electric starter first try. The carbs need to be gone through and synced but it is very ridable in the state its in.

Vision:
When I first saw pictures of the bike I thought it was going to be a restoration project but after giving the bike a once over I really don't think its worth it. The previous owner looks to have tinkered with it quite a bit, so I don't plan on keeping it stock. I won't café it though.

June 2nd:
Back to the tank... Yes I now know this is not the original tank thanks to some members on here. Its off of a CL350. I have a CB360 tank in the mail and should be here by the end of the week. Today I started tearing the bike apart, starting with the tank. I took a hair dryer to the fuel lines and they came off fairly easy.

Trying to dry out the tank

Fuel I drained from the tank. A lovely orange color

The frame needs to be repainted so I started tearing off some of the accessories as well.

Current Goals:
-Clean, rebuild and sync carbs
-Clean and seal new tank
-Install new Cam Chain Tensioner and Guide
-Adjust valves to spec
-Set timing
-Powder coat frame

Questions:
-Since the bike was running decently before, should I do one thing at a time for the sake of easier trouble shooting? Or do all of the maintenance at once?

Nice looking little toy, should be lots of fun.

I am a fan of doing things one at a time or at least things that can be troubleshooted together because they cause very different issues.

In your case, clean and rebuild carbs and clean and seal the tank can be done at the same time as it is fairly easy to troubleshoot a non functioning tank or petcock. I can not stress enough how clean these carbs need to be. All the passages need to be checked for actual airflow, the slides need to move freely, jets clean. I would recommend using OEM jet parts though, most rebuild kits have incorrect ones.

With all that said, if you think its running well on both sides, then get the tank cleaned, pull the carb bowls off the carbs with them still on the bike and just clean the crap out of the bottoms of them and put them back on. I find that small dabs of grease will hold the o-ring in place while you put them back on. Then FIND some real gas and use some Seafoam as recommended for at least 2-3 tanks. I still try to put some in mine just to help keep them clean. Removing working cabs from a bike can be one of the hardest things to get back right on a 360. I have no idea why but they can cause all kinds of heart ache and pain.

Did the bike get the cam tensioner recall in the first place? How many miles is on it? I agree its an item that needs to be looked at but if yours is a 74 and got the recall and its miles are low then you can get away with that part for while. I still have a factory one in mine and I helped test the available replacements. If it didn't get the recall then yes replace it.


Far as the rest of that, timing and valves sound like regular maintenance, the powder coat frame part is winter project, if it looks that bad just mask it off and rattle can it for now. Its summer time, riding time.

Great info thanks! You've made me second guess taking them off now. With the orange gas and the disgusting petcock I pulled off yesterday, I think I want to take the carbs off and clean them thoroughly.

No it didn't. At least the serial plate isn't stamped. According to the odometer it only has 2800 miles. I'm finding 2800 harder and harder to believe... The tank and the headlight aren't original. The tank was terribly painted. A lot of the wiring isn't routed like factory. But maybe it does. I don't know why anyone would go through the trouble of replacing the gauges.

The more I stare at the bike the more I agree with you
