I made you one out of WAGO style quick connect terminals. A multi pack is $10 at Harbor freight and I'll never use them all. If the ring terminal wire is too long you can cut to suite (leave the ring in place and cut the upper wire at the connector) twist it and the jumper together insert into the terminal and snap the orange lever down.

I can epoxy then back to back or leave independent.

PM me an address where you'd like them sent and I'll get them in the mail tomorrow or Saturday or if you are going to be up Chambersburg way stop in. Or if you wan tto roll your own let me know and I'll disassemble and put the connectors back for another time.

 

I like to keep my battery post clean, without any other accessories, so I wired a positive wire (from the alternator) and a negative (from the ground post on the motor) to a fuze block. When I remove the battery, no need to juggle with multiple connectors.

 

There are a couple of easy commercial options for this.

Bluesea makes buss bars that all use screws/studs so they are reliable. Bunch of places sell them.

A high density but more DIY solution is go do to Home Depot or any commercial electrical house and buy a
busbar made for breaker boxes. You can cut them to whatever length you need if they are too long. Downside
is no built in insulation and mounting. They are just made to be screwed into a heavy gauge steel box.

May not be relevant, but to gain space in the battery box area (top of battery), I rewired fuse holder out of the battery box and to an area under seat where there is literally nothing. It made unobstructed room to terminate to battery posts.

 

The latter watercooled bikes do not have a lot of free space under the seat

 

That's my problem - tight on space to add anything that is remotely bulky. @PerazziMx14 I've sent you a message and feel free to contact me back on my mobile number.

I also added some double sided tape to the back of the terminal connectors in case you wanted to stick them to the ECU. If you don’t need the tape it will pull off.
