'74 CB360 cafe project - (New clutch springs and back to analog gauges.)

'74 CB360 cafe project - (The Green Meanie isn't quite finished yet!)

OH and BTW whats all those parts and such (tank) back there?

Good eye. The tank is a fiberglass one and there's a glass seat pan too. Those belong to a buddy that is doing a triumph flat track bike. I am going to paint them for him in a couple of weeks. I traded him a paint job and some cash for an xs650 project that I'm going to start on after the 360 is squared up. The wheels you see there belong to the 650. I'm going to do a hard tail on that.

Yeah Clinton Lake could work.

Careful, you might turn pro builder, then I wont speak to you anymore...wait maybe that would be doing you a favor.

Check the drive chain isn't too tight or too loose, either causes vibration in footrests (too tight is worse)
You should have starter plug in a few days

The vibration isn't really that bad, just made your feet tickle... I did just tension my chain again as I had to use my rear axle to pull the alternator rotor. I think I have it at a reasonable tension. I am pondering my drive sprocket. Currently I have a 17 tooth sprocket on there... really makes it easy to cruise at 60+ mph (I'm sure I've done 80 and had plenty more to go...) I am probably sacrificing some grins by not using the stock 16 tooth, But I am worried that I'll be unable to hold interstate speeds without keeping it wound up... I'd like to be able to take it on tuesday ride night with a group of friends but they ride a mixed batch of bikes and can be pretty speedy.

Should I give the stock sprocket a try or stick with the 17 tooth? I still accelerate pretty quick but front end definitely stays on the ground. (should be better with the new clutch springs too.)

I've never used a 16 t sprocket, even on 250
17t gives around 125mph, depending on tyre fitted (if you had the power to pull it)

CB360 was never a wheelie machine....In good tune and ready to go, the wheel might lift an inch in 1st or second.

Problem with running lower RPM is that you don't charge the battery as easily....

I try to stay above 5k RPM, no lower than 4k when running....

Vibration can be reduced by sync'ing carbs and after running, loosen and retighten all motor mount bolts to relax the motor in the frame. They will never be vibration free, but they usually can be improved a little.

Speedometer is hooked up now, I ordered the short Motion Pro speedometer cable. Man there wasn't much slack... good thing I mounted the gauges as low as I did.

I also went ahead added the constant current charging unit that I picked up a while back. I had room to add it after removing the starter solenoid. We'll see how that works out...

 

[3DogNate]

Here's a pic of the constant current module installed. The tail section there isn't water or air tight but it stays pretty dry in there... I got caught in the rain one day and had no issues with it getting wet in there. Still need to add the battery tender pig tail.

 

[crazypj]

Did you get starter plug yet?

Not yet, was hoping for Sat... But I'm sure it'll turn up Mon or Tuesday.

I also just turned a new brass bushing for my right hand brake lever... Took the wobble out of that, much better. It would jingle when I rode if I didn't keep my finger on it.

 

[crazypj]

I'll dig out receipt and find tracking number, pretty sure it should have got there Friday/Saturday
USPS site is down so can't track at present
here's number anyway

Constant current unit...looked at earlier post, didn't find anything?

Any info on it? Brand, website? what does it do? Call me intrigued...

Ensures constant current. ;D Sort of like a mini regulator just for the battery. Acts like a trickle charger. Available from eBay for around $10.

 

[3DogNate]

It's an AudioWind A-260 / I think Electronics Salon is the seller on eBay... Look for Fatherjon's CB360 build here... it's covered there. Need to add a Schottky Diode as well to allow the unit to supply power from the battery to the bike but only charge the battery from the A-260 and not the stator. (No idea the model diode that I bought... It's all in shrink wrap now, can't look at it.)

There's a couple more 360 guys that did this and love it... Trek97... Eric, did you add one of these also?

Update... here's a good link for you Honda007 posted the schematic for how to hook it into the wiring.

[trek97]

nope, I havent done any of that. I still got the original stock regulator on mine. One of the only "original" pieces left to my whole bike. LOL.

anyway I will try to find the post. But that kid that bought Fatherjons bike. Made just a post or two about it. A couple days after he got it home...the thing pert near burnt to the ground. I will look for it.

Yikes...

 

[trek97]

OK maybe not to the ground. I was thinking of something else. But it did FRY the battery.

From research, battery doesn't work if bike doesn't charge at idle, eventually, voltage drops below 'safe' limit then it acts as though it's being overcharged and fails
Doesn't matter how well regulator 'clamps' voltage to prevent overcharging, if voltage gets too low and battery isn't put on special charger it's going to go pop

Well, this is one reason I didn't go with a Lithium Ion battery, they are so freaking picky with charging... and don't handle vibrations well..

I'm using an AGM battery, I also ditched my battery tray and went to just a strap to hold it with a bit of foam underneath to give it some room to wiggle around and not get shaken to death, the tray fit pretty tight and made for a pretty rigid mount, I may make a slightly over sized tray so that I can fit a rubber boot in it and rivet that in. AGM batteries are more like a Lead Acid battery... but still can be fussy on a charger evidently

 

[crazypj]

Yep, AGM can cope with a lot more than lion battery (decided I'll call all of them 'LION' batteries from now on ;D )
Really the only 'disadvantage is you can't top them up when they dry out (even recombinant gas technology do eventually)
I wouldn't even consider LION unless I was racing and needed the weight 'advantage'
