Restomodding a 74 CL360

Worst cb650 ever said:
I can't help with the dead battery, but here's a link to where you can download the factory service manual:

It is very helpful!

You can check to see if your carbs are getting gas by loosening / removing the drain screw in the bottom of the float bowl. Gas should come out when you open the screw - if not, you're not getting gas to the bowl and you need to start looking at why. PJ knows these bikes in and out and does a mod to the carbs that lets you run pods without sacrificing performance, and his price is very reasonable.

Thanks for the link! Downloading now. And speak of the devil...

The drain holes in the drain screws are frequently blocked so you must remove them rather than just loosen.
It's another one of the things I check/clean/modify

I'm hoping to get some work done on the bike this weekend, since I'm going to be busy getting the Magna finished up. New tires for the Magna installed tonight! I need to derust her and get the radiator overflow hooked up again.
 
Yea, listen to PJ! I was assuming ideal shape carbs, which as we all know don't exist on project bikes ;D

So, time to drain and remove the tank, pull and clean the carbs, install the new cabling, and figure out what to do next.

Stick carbs in a box and send them to me ;D
 
I went to the motorcycle show yesterday. Got to sit on the new CB1100. Nice bike, probably the only non-cruiser 1100 where I can put both feet on the ground. The antique Japanese bike guys were there, and there was a fully restored CB360, so I talked to the owner for about 45 minutes. That bike was in showroom condition. It should be nice the next few days, so I'll be doing some wrenching if I can get home in time. The battery is fine, according to the dealer, so it looks like there's a problem with my charger/tender. I'm ordering some parts this week, hopefully I can get the carbs off and shipped next weekend.
 
I have a new lithium battery on the way from Michigan. 2"x2"x4". While the carbs are out of the bike, I'm going to pull the battery box and build a smaller one for the new battery. Or I'll find someone local who can fab it up, since I lack welding equipment. That takes care of the heavy lead acid battery and leaves room for the pods. Since I'll have the battery but no carbs, I'm going to chase down the short in the right turn signal. I'm also going to strip the tank and side panels of their cheesy rattle can paint jobs. I still need to source the badge holder thingies. I've been told they're still available through Honda dealers.
 
The lithium battery came yesterday. I re-installed the lead acid battery to start the bike and see if there was any love from the right cylinder. The bike started on the second kick with the choke fully on, which it didn't do before. As in, it wouldn't run with the choke on. Anyway, I let her run for a bit, then turned off the choke. Still running. I covered the left cylinder's opening with my hand, the bike continued to run for a few seconds, then it slowly died. I kick started her again, let her run, covered the left carb, same thing. This weekend, I'm going to start her up, get the oil warm, and try to drain the oil before I pull the carbs since I also got the new drain plug yesterday. I have not taken a bike down this far before, this should be interesting.
 
2x2x4 battery sounds pretty tiny, you should be able to mount that off the toolbox mounting real easy (or even cut up toolbox?)

That's not a bad idea. Since I'm tearing her down anyway, I'll see if I can route the lines that way.
 
I need to take the exhaust off to get the carbs out. Brilliant! And there are a couple of things attached to the battery box preventing me from pulling said battery box. I'm still trying to figure out how to take those off before I can pull the box. Any ideas on what they are and how to remove them? It would probably help if I had better lighting but the weather did not cooperate Saturday or Sunday.

ETA I did manage to get the gas tank off after emptying it. Some blue paint was in the petcock screen, I wonder if there's paint chips blocking some of the gas on the right cylinder?
 
Why would you need to remove exhaust to get carbs off? those high pipes would get in the way of pulling the bowls off. but not the complete carbs set.
It will get easier after youve had em off and on...1000 times.

The exhaust pipes line right up next to the section of the fram that the carbs are supposed to go through. At least according to the manuals I've read.
 
Take carbs out to right side, it's MUCH easier than going left Sometimes the manual is designed to screw you over ;)
I would disconnect fuel lines and breather tubes then put choke ON so it clears frame. I do this a lot, clutch cable is also in the way if you 'go left' ;D
 
HUH, Ive never even considered trying to take the carbs out the left side. Im glad I didnt see that in the manual. the right side is very easy w bike on the side stand.
 
I'm also having issues pulling the battery box out. It appears that some electrical parts are directly attached to the battery box. However, the parts won't come off the box. I put a question on Honda V-Twins and got a link to the fiche, but it doesn't show how those parts are attached. Either that or I'm not seeing it.
 
It was still pretty weak. Tonight, I'm dropping the 85 Nighthawk off to get the clutch plates and springs done. 36,000 miles, I guess it's due. I'm so glad it doesn't need valve adjustments.
 
Sounds like an easy job you should attempt it yourself....Lots of people on here more than happy to walk you through it or post links to the same job being done

No more room, the other project Hondas are taking up space for something like that, plus I don't have the castle nut wrench to take out the plates. The Nighthawk is the only Honda I have that actually has a full tag, not an Antique tag, so it's my commuter bike.
