Carb ballancer

What's the best/easiest to use I've got a Morgan carbtune 2 but it can be a bit of a pain sometimes

Cheers Martyn

I borrowed a carbtune and thought it was better than the davida gauges i'd borrowed the previous time.
Must get me own lol.

If your rolling in it, the electronic vacuumate is a great investment. I have one. A fairly pricey bit of kit but couldn't be easier matching up the 4 stacks of leds. It has 3 overlapping scale ranges. They're very sensitive, the slightest touch of a balancing screw and the leds change position which can drive me nuts as I find you're chasing your tale to get the levels bang on, But even if you don't the carbs would be well within the required spec. You also have the adding bonus of running a dynamic wave setting and can check for inlet or exhaust valves, leaking manifold etc.

not rolling in it by any means i think i may carry on with the morgan carbtune

I bought a set of theese, I know people give them stick, but I found once I'd checked they all read the same (testing each one in turn on cyl 1), they were fairly accurate (well my GSX now runs smoother after using this set)

Just my opinion after trying a few different sets of gauges over the years but you wont get better than the morgan carbtune for the price, yes that can be a bit of a pain on some bikes but that usually more to to with the user rather than the tool

I swear by the Morgan unit. It takes a bit of practice to get the feel of it - but it is accurate as f*ck.

I borrow a mates, Davida style ones. As most have said, once I got the hang of it, they seemed accurate enough for my Gixxer to run a hell of a lot better! Just stick with what you've got and persevere!

I static balance mine first , here is a copy of a pdf I use

works fine with me and nearly always spot on then I check with balancer

"Old Skool_R’s How To: BENCH SYNCHRONZING YOUR CARBURETORS
Tools needed:
1 long zip tie
Phillips screwdriver
Vernier calipers
So after your carbs are all cleaned up, you should bench sync the carbs
to get them close. It’s recommended the carbs should be synched with
a professional sync tool after you get the carbs on and bike running.
Note: I have bench synced my own carbs using the method below and
then synced them with a mercury manometer and they were VERY
VERY close. All cylinders were on except for one that needed a very
small adjustment. So if you’re cheap like me, and don’t want to buy
the sync tool, this method should work fine.
First thing to do is zip-tie the throttle lever open all the way. You can
look in the picture to see where I ran the tie. I believe this is the best
way. After you have the zip tie on, manually try to open the throttle
more, if its open all the way it won’t move any more, if you can still
move it, you need to tighten the zip tie more.

Starting with the carburetor that has the throttle stop (see pics) you
will need to measure from the bottom of the throttle blade to the
lowest part of the throttle bore. Right before you get the caliper all the
way to the bottom of the bore, rock it back and forth a small amount.
You will feel it drag, then get loose, then drag again. When it loosens
up, you are close to the lowest part of the bore. Roll the micrometer
down until it hits the low spot then record your measurement, then
move to carb #2 and adjust it to your first measurement. Then 3. Then
4. Measure and adjust in order 1-4 (see pics)

Measure this carb first, it is the base setting for the rest of the carbs

Red circles show adjusting screws.

Example: You can see in the last pic the base carb measurement was
0.664. So now when i measure carb #2, if the measurement is 0.667 I
can turn the adjusting screw between carbs #1 and #2 until the
measurement for carb #2 is 0.664, the same as carb #1. Do the same
for carbs 3 and 4, then you’re all done. Easy right? "

Ive used this a few times and  found it spot on about 99% of the time,

hope this helps

That's a neat way of doing them on the bench/cheap.

Remember, ALWAYS adjust the valve clearances first, then the carbs.
