For single Mikuni...Thunder Products makes several products for Mikuni VM carbs...the one that's easiest to install and requires no adjusting with jets. It is called the Torque Wing and fits into the motor side of the carb with a tiny bit of modification. It's presence is felt just off idle when the throttle is quickly opened. I have so far installed it on two Nortons with good results. If you can get an improvement you can feel for only $100, grab it.
His praise for his products is a bit over the top but he really knows what he's talking about. I would like to hear from anyone who's used one.

UFO stuff?
 
My concern would be about the engine swallowing the screw or getting stuck with an open throttle.
 
Same company but something else. The UFO works very well but requires fiddling and jetting. The Torque Wing is just one step..install.

This seems awesome, but my thoughts exactly. Too bad there's not a better design on attaching it
 
Actually not so much. They are mainly for wide open throttle but we do use a Innovate meter
Well you really do. Hope you aren't using this as a set it and forget it. If so, it's a waste when you could just dial in the proper jets. The functionality comes into play when you need to change your A/F on the fly, say changes in elevation or a dual street/track bike. And if you adjust your A/F on the fly, you really want to know what your A/F is. I would think.
 
As I said, it works. $100 is cheap for that. And I will mention it again, A pair of Denso IW22 - 5307 iridium plugs will make a noticeable improvement.
Better than NGK BPR7EIX?

Also - according to that site one of these for a single VM36 is $35 - no?
 
A mate of mine is obsessed/besotted with his big bore trident
He has 30 mm amals on his bike and the bottom of his slides are faired with araldite
I'm guessing it does the same as UFO claim ?
 
I'd like to hear if they work with twin carburetion on a Norton. In particular 35mm FCR carburetion. I want to know how hard I'd have to Hang On. :)

That's great you have experience with them! How many have you installed? Did you use the deep bowls? What meter do you use? Do you have a collection of headers with bungs for testing like we do? Did you use high-flow petcocks or did stock work? It would be awesome if you could share your experiences so I can compare them to what we have experienced at the shop as with our latest Bonneville Speedway bike we have installed a dozen of them in the last couple of years but maybe you have some better insight that could help us. I would think if you have installed many of these, you would know they can be set and forget and many are but we purpose adjust for what we build for here at the shop. As I'm sure you know for bikes that typically run at sea level-3000 it makes it a breeze to rejet for high altitudes on the fly. No meter needed when you can jet up to the proper main by a dial.

Here is an excerpt from an article written about them. and just a reminder about what I said "but we do use a Innovate meter" but really spark color has gotten close enough for most.

You could actually install it, set it and forget it, just like your plain old main jets, and still benefit from the improved performance of having more accurate fuel delivery across the board. But those who do pay attention to their exhaust gas temps, spark plug color and piston wash are going to benefit the most as they will be able to keep this edge all of the time, quicker and easier than ever before.

Look forward to your responses!!
