CB360 Carb Sync Tool Kit

[Matnetik]

Thought I'd share this on this forum as well -

Thought I’d share some links for my setup to create a carb sync kit. Have had a hard time finding all the pieces - everything I purchased to sync the carbs is below!

Carb brass fittings 6mm x .75 (if the link ever expires, search eBay for “6mm x .75 muzzleloader nipple”)

Two way valve splitter (to use 1 vacuum gauge)

Valve regulator (to provide steady vacuum so the gauge needle doesn’t jump all over, you really only need 1)

5mm vacuum line (enough to split between each carb)

5’ 5.5mm fuel line (to connect gas tank off the bike)

Fuel line connectors (to extend the lines to the carb)

Carb sync wrench (not totally necessary but it’ll be a nightmare without it, trust me)

Vacuum gauge (if you wanted to, you could get two separate gauges and eliminate the two way valve splitter but up to you, I prefer one gauge for accuracy)

Pictures below, hope this helps those looking for a setup. All in all it’s about $100 for the whole setup. Common Motor also sells a kit for around $75 which is definitely a GREAT deal but have been out of stock and I’ve been needing to sync my carbs for awhile now.

These are the brass fittings for the carbs


I used a drill bit and drilled the hole out just a bit for better vacuum flow


Here they are attached to the carbs, I do wish they were a bit longer but the clamp helped


Here is the setup, the regulator and splitter worked PERFECT for syncing them


And here is the gas tank on a table connected to the carb gas lines with the fittings

I just stick a bit of metal rod underneath each slide then open the throttle and adjust the cables till both rods drop at the same time

But I do this on my old British bikes , it maybe not so good on a more modern Jap bike

Oh yeah I always bench sync but the 360 is so finicky with the carb sync, the vac test is a must. Fixed my high rpm that didn't want to drop for 4-5 seconds issue!

Made it on DTT for first time in months.
Still 'displaced' and living in a hotel since Hurricane Ian at end of September (at least the new hotel is far better than the' shack full of drug dealers' insurance company originally put us in)
Kinda surprised CMC is out of stock, I made several hundred sets of vacuum adapters for him a while ago plus it took more than two years to sell the last few sets I had 'in stock'.
You can get the individual parts quite a lot cheaper than CMC kit if your prepared to do just a little hunting around.
The 'special' screwdriver with 8mm socket is about $25,00 on e-Bay or Amazon, (I have seen them as low as $17.95), I think it's from K&L Supply? vacuum gauge at Harbor Freight, about $12.00 to $15.00 (depending on what coupons you use) and vacuum adapters (when I have them) about $15,00 including postage.
