Alright that's why I couldn't find it at A Viscious - it's at Arrowhead.

Unfortunately Arrowheads site doesn't make it easy to post direct links and they don't have much of a description.

Anyway it's a Mikuni Performance Carb Replacement Kit priced at $266.

The description: Easy bolt on plug n play installation, greatly improves throttle response, very tuneable.

Interesting for sure. Would be interested in hearing some feedback on it too.

Faster throttle response seems obvious; plus--marginally less restriction from the absence of the butterfly in the slide carb.

The Arrowhead kit is NOT a pumper, IIRC; i.e.--no accelerator pump. Research on the Mikuni website disclosed no pump; again, IIRC.

Some comparative dynamometer data between carbs, all other things equal, would be interesting.

Other than quicker throttle response with a slide carburetor versus a CV carburetor, I do not discern any mechanism producing increased power by significant magnitude between the two, but would appreciate an explanation from someone who does.

A pumper dumps raw fuel into the venturi, but only on the opening stroke of the throttle. Thus, the accelerator pump is inactive during steady-state operation, and cannot contribute towards enhancing power output under that condition, seems like to me.

Then, there's the 'Lectron carb . . .

------------------

All that said, nothing against those who weigh the cost/benefit ratio of a slide carburetor; more power to you, if you find it favorable!

From Arrowhead marketing info, the product now provided has vacuum port for fuel petcock.

The VM38 that Fred at Arrowhead is selling is the same as the one I installed as a complete kit - carb, jetting, throttle/cable. I worked some with Fred to bring back this carb. This carb had been a kit years ago from White Brothers that included a pipe. I put over 5,000 miles on this carb this last summer and nothing but good to say about the carb. No power gains to speak of, but better response and maybe a little better lower end. The biggest feature is the simplicity, accessibility and ease of tuning. Easy of maintenance is tops, especially compared to the CVK.

Wansfel thank you that is exactly the answer I was looking for ,and now more questions .
Is your bike stock or what changes have you made ?
Mine is an 05 685 kit ,dynojet stage 2 1-1/2 in opening on the air box uni filter the exhaust is reworked and the exhaust cam one tooth as per Mike . The Mike exh cam really smoothed the bike out ,I,m looking for a little more in the 4- 5 ooo rpm after 5 the bike comes on beautifully and the low end is great ,that's where I'm hope ing the slider will help ! Thanks again Doug
