Product description

We have been asked many, many times to produce a kit for the Virago 750/920.  The wait is over!

Brand new carburetor kit consisting of genuine Mikuni 34mm carburetors, pre-jetted with proven specs utilizing genuine Mikuni components.

  • Pre-jetted carbs for stock to mildly modified engines
  • CNC machined bolt on flange adapters with perfectly mated rubber connectors and clamps
  • M6 x 1.0 threaded hole in each manifold for carburetor syncing - with stainless plugs
  • Correct assembly length for use with the stock air tubes
  • Stainless steel flange adapter allen bolts
  • 1-2 cable for use with the factory throttle assembly and some aftermarket units - 42" case length
  • Additional jetting included.  2 Sizes of mains, and 2 sizes of pilots
  • Viton, ultra high quality, high temperature manifold o-rings

We don't just swap out the mains and pilots.  Slide, needle jet, needle, main, and pilots have all been chosen for the best possible combination.  Due to the engine design of the 750/920 we opted to swap in the knob style choke assemblies for easy access.  Because each bike is different, and because these are shipped all over the world, we cannot guarantee out of the box compatibility.  Climate, altitude, and engine setup all play into the fuel requirements that must be met.  We include the additional mains and pilots for such occasions.  Most customers will find they can install and run the carbs just as supplied without any tinkering.

We CNC machined our flange adapters in house and paired them with perfectly sized, high quality English made rubber connectors.  When we designed our flange adapters, we mimicked the Mikuni spigot indent for a perfect fit, and perfect seal on both sides. These rubber connectors are not your typical straight, green stripe, radiator hose. When used with our flange adapters, they allow for a nearly step-less transition from manifold, to rubber, to carburetor.  The reduced turbulence through the intake means more efficient operation for more power, throttle response, and efficiency.

Custom made, high quality 1 into 2 pre-assembled cable for easy installation.  Cable is good for close to stock style bars and shorter, and is designed to work with the factory throttle housing and some aftermarket units.

Good carbs, needs a few things but runs good once you get it right
Red ,
Good carbs, do require some tuning, not an out of the box install and run deal, kit doesn’t come with provisions to use the factory vacuum petcocks on the virago’s and that should be included. But now that I’ve got them tuned right the bike runs good

Marko Sharko,
I have not had running yet, however the fastest delivery I have had from the US to New Zealand ever, 3 days flat, impressed. Reasonable shipping cost not like some other companies.
The only thing I have noticed is the OME air filter boots that come from the frame to the carbs do not fit, they are not long enough, not sure how to deal with that yet but have no doubt I can fabricate something to look OK.

Solid carbs, look great, feel great, don't let them get away withholding parts they should have sent.
Chris,
The carbs are great! Haven't gotten her up and running because I didn't have the right fuel lines (these mikunis need bigger than stock) I can feel the difference in the snap back though - I can tell it's gonna be nice. My only complaint - I was not sent the extra jets mentioned in the listing and now I'm going to have to take extra time to go get those sent to me. It's been a while since a business has failed to sent me what they put in the product listing.

Looking for new carbs for your XV ? Look no further, this is the real deal
Mark,
I purchased this carb set for my 1982 Yamaha XV 920. The kit comes complete with everything needed to install new carbs; including the proper jets required ( this is a science of its own, finding the correct jets ) high quality flange adapters, a 2 in 1 throttle cable, and all mounting bolts needed. The carbs fit perfectly on the motorcycle allowing use of the stock airbox hoses. The complete installation required two hours, and I took my time as a backyard mechanic. Because the carbs are pre-jetted they were almost perfectly dialed in, my bike started without a hitch and I was ready to ride the very same day. The results are nothing short of astounding, the low and midrange are much stronger, the bike runs better then ever. I highly recommend this product, as well as the support of the staff.
