CB360 wiring plan

Hi guys,

I'm in the planning phase of the electrics for my bike (74 CB360 soon to be a CB390). About the only thing that I am certain of is that I will be using a smaller than standard battery since I am dropping the side covers and filters. Most likely the EarthX ETX-12A.

I will certainly go with a modern regulator rectifier (either from Sparck or Rick's). Can anyone speak to the differences?

I may also upgrade the stator. I see that Sparck Moto had the tri-spark at one time. Anyone know what happened to that offering? I don't see that on the website at this point, so that kind of leaves me with Rick's for a choice - in which case I'd go for the package deal and use their reg/rectifier too.

I will be running LED everything: head, tail/brake, signals, dash… and I am really thinking about the m-unit and Purpose Built Moto's pushbuttons, but I might go the other end of the spectrum and build a harness around a fuse box - kind of depends on how long I want to wait for finances to match my desire to move forward.

To me the choice between an m-unit and a "just-a-harness" is a decision of desire. I think I can reach the real end goal of the bike either way (although with clunkier controls in one case). On the other hand, having the proper charging system to support the battery is a requirement. So I will spend what I need to there.

Here is what I am looking at, not including any harness work:

Minimum solution - EarthX battery and Sparck's regulator: @ $210
plus 1 solution - above, but with Ricks Stator (and reg): @$400
M.unit Blue + M.button + 5 button controls: if I am going here, it will be full Monty or nothing: add @ $600

So the from "minimum" to "all out" is about $800 or so extra into this project. What do y'all think? Is it worth the $$ and would you recommend anything different?



BTW, my really bad build log is here: https://www.hondatwins.net/threads/74-cb360-brat-ish.130246/#post-1093264
 
I'm not sure of the exact specs of the Rick's unit, but ours was specifically designed for use with the Honda twins. It's LI-ION safe and definitely up to the task. Charging comes on sooner with our unit and have thousands of them out in the wild.

We still have Tri-Sparck units available, but I haven't put them on the website just yet because I haven't had enough customer feedback about them. We have about 20 sold and I know at least two have been installed with positive results, but I didn't want to open the flood gates until I received more information from our customers. If you wanted to pick one up, I'd be happy to provide it at our pre-order price of $200 (final retail will be $250 on these once we do start selling them to the general public). It includes the necessary R/R for the three phase operation and also includes detailed installation instructions. Modification of the side case is necessary for fitment and a mill is recommended (though I have made the modifications a few times without a mill).

M-Unit is a bit overkill for a vintage bike, but there's no denying the bling factor. If money's not an object, go for it. Don't expect it to make your life easier, though. M-Unit actually adds complexity to a bike of this age.
 
Awesome!

I was hoping you’d chime in, but I didn’t want to call you out directly. Good to know the Tri-Sparck is available.

That’s what I suspected about m-unit. I’m actually not too keen about having the constant draw of Bluetooth on the battery, nor do I want the associated headaches, but I do like the simplicity of a single-central unit that handles circuit protection, ignition, led indicators, brake light pulsation and allows for push button controls. Just not sure that it will really add that much to the ride experience at the end of the day.

Maybe I should just grab one of your harnesses and regulator and battery (and maybe some new switch gear since mine is in pretty bad shape) and call it a day? That would certainly let me wrap this thing up several months sooner.

I could always add the stator afterwards if I see any charging issues (albeit for $50 more at that point...)

Now if PJ can just find some time to get to my carbs!

That would probably be the cheapest and fastest option.

Hey behind me pls, I've been waiting for 2 years

Just kidding..

I'll check your build on HTwins.. I may have some questions on your 390 conversion.

Currently I've the cheap R/R mod. I've not tested on how well it works.

Agree with you on M unit, it's cool, but I'm not convinced to go with it for perfectly working wiring on my 360.
 
I've never found the need to wire a Honda twin, especially a 360, with an M Unit. The wiring is so simple as it is. I've never found the need to wire an SOHC4 with one either. My BMW R100/7, that's another story.
