I have my stock amals on my 72. I have yet to discover what the problem is with amals. They are simple to set-up, give good service and replacement parts are affordable and available and they, well, look "right" on a Bonneville.

I've used the VMs for many years. Very realiable and just don't wear out like the Amals.
However, lately I've started using the JRC flatslide PWKs. They look at lot more like an Amal, better throttle reponse then the MIK and easier to tune. Quality is marginal.
Probably the best carb would be a Mikuni TM, but you would have to be innovative with the mounting and be willing to spend a few bucks on jetting parts to get it dialed in.

I have used Mikunis for some 5 years now and no probs - Personally I had bad experiences with Amals over the years hence the change to Mikunis - however if I were replacing carbs again I would very tempted by JRC flatslide PWKs.

The miks were performance based and a pig to set and keep in tune with so many variables. The amals are much simpler and some say inferior, so it really depends on how often you want to tinker with them.

You'll need mikuni manifold stubs that bolt onto your head inlets, rubber sleeves and crimp rings to then fit the carbs. Throttle cabling is a straight fit from the Amal set up. I can post pics if you want to see how it will look.

Cheers.

R these on a 500? What kind of throttle response do you have and what size jets are you running? THANX!

If your bike is running a pair 26mm Amals then the following jetting for Mikuni Vm26 's jetting is:
Pilot jet 20
Slide 3.0
Needle jet type 182
Needle jet size N8 or O0
needle 5F21 on the 3rd clip notch
Main jet 130
Air Jet 0.5

I was wondering if the 930's were to large?

WhAt is standard size for the T100R ?.

The danger of fitting too large of carb is you can actually over- carburate which can have an averse effect.

References seem to be saying that's inch and a sixteenth Monobloc, which is just about exactly 27mm. In general, people replacing that size of Monobloc with a Concentric go for 28mm 928. When Monoblocs went out of date the factory actually went for 26mm 926.
