UPDATE-Purchased and installed brand new shinny VM34-168's and a new Kawasaki throttle cable.

The good-
- runs amazingly better- no changes. Need to do full ride/test still and adjust, but impressed thus far.
- Look nice


The Bad-
- had to take off the neutral indicator switch off- was hitting the bottom of center carb float bowl drain bolt...was causing it to angle up. I also cut the boot/adapters about an inch or so- moving the carb right at/touching the manifold, but it wasn't enough to keep the neutral switch.
- Getting the fuel line on was a PITA! Larger size inlet.


Scott- saw your comment about the cable /chokes in my other post, and yes, I will need to do....or at least the individual black/pull type. The lever types that came with it are right against the fins and had to remove the center one all together, wouldn't fit- was hitting?

From what I saw posted at Sudco I figured the -168s would be close on the jetting.. Your mounting setup and carbs looks almost identical to mine. My carb's end is now .75+ away from the cylinder manifold surface (center carb's top against fins), which is slightly closer than the usual adapter block and rubber manifold (the closer to the bore the better). I got so pissed off with leaking gaskets I JB welded the darn adapter manifolds to the cylinders!!

I too cannot run the neutral switch and had to cut a notch in the sprocket cover to clear the brass nut on the bottom of the bowl.

You may want to remove most of the plastic tubing. If the vent (top tube) gets pinched disaster looms. The plastic also tends to melt

Keep an eye on Cody's jetting thread regarding ping coming down from WOT. I'm running a 6DP1 needle/p6 needle at the moment but will be going to a P5 next (presently rich down low likely due to UFOs)...

Hi,i have sold quite a few Mikuni vm 34s ( round slide) with new intakes ,and filters,on Ebay.Each set is cleaned and checked for worn-out components.i could sell without filters,if desired.Thes carbs are the largest size available for the H2 without intake mods.

When I got VM34s for my H2, and used the Mikuni rubber adapters made for them, I needed to do some port matching because there was an obvious step where the port runner was smaller than the adapter.

If it surges, that's normal, upshift.

Small body carbs are made of zinc and are as heavy as all get out compared to aftermarket aluminum carbs and of course they come with 1.5mm float valves for sleds with fuel pumps. Either fit a pump or replace the valves with something larger.

Slides are OEM and I guess it might be possible to buy a different set through a Polaris dealer, but that may be spendy. Increasing the cutaway can always be done with a file or Bridgeport mill or an angle grinder . The rest of the brass is all stock type stuff.

My set including replacement brass and gaskets was just over $100, so they are a cheap alternative.

Thread back from the dead.....

I came across this set of carbs, was told they came off a H1 - They appear to have 250 mains, possibly a alcohol engine? VM30-83's I believe.

6F5 needle, 40 pilot, 2.5 slide, seems all the "stock" stuff

I dunno, thought they were cool.

Solvents and Steve do not mix, having sprayed them off quickly was enough for me to feel like crap. I used to do gym floors and now solvents make my life a hell.....

Anyway, here are some pictures, the Tommasseli throttle sure looks cool.







All the pictures here, hope to have these on eBay ($99.99 seems like a fair opening price) as you read this.

Wish me luck, and any input welcomed - I've been told these will not fit a 500 and only fit the 750 - anyone know for sure?

Maybe it's just the neutral switch issue, as mentioned....

Here is the listing if anyone is interested in them - http://www.ebay.com/itm/130806409377?ss ... 1558.l2649
