DOES NOT INCLUDE INTAKE MANIFOLD!
Yes, we know there is a cross-member in the way on your buggy. No, the carb isn't too big to fit, and the boot isn't too small. Use these instructions and you'll be up and riding without busting too many knuckles.
Also note, your original cable will need to be modified to work with this carburetor. The end-ball will need to be rounded down to fit into the slot of the carburetor.
This is an Authentic Mikuni VM26-606
There are a number of knock-offs out there. We source ours through official Mikuni distribution. Others pass of the less expensive 8074 version (for two strokes) as the 606. You will receive an actual Mikuni produced "606" carburetor from us.Please note, your original cable will need to be modified to work with this carburetor. The end-ball will need to be rounded down to fit into the slot of the carburetor.
Mikuni VM26 Round Slide Carburetor (with manual choke)
This 26mm carburetor (stock is 24mm) opens up the top-end power of even a stock 150cc GY6, and really makes a difference when combined with other engine modifications. In addition to more power on top, throttle response and low-end grunt are improved from the round-slide design.Not all VM26 carbs are created equal! This is the proper version of the VM26 for our buggies/scooters. Other VM26 models are for 2-stroke engines and have poor performance on the GY6.
Jetting requires trial an error, and you need to have a decently researched understanding of how the tuning process works. We can't help with that. But to get started, we recommend this starting points depending on your engine size:
150cc - 17.5 pilot and 150 main
175cc - 22.5 pilot and 175 main
186cc - 22.5 pilot and 185 main
In our experience, the jet size needed correlates pretty well to the CC size of the GY6 platform, taking into account basic mods like the UNI Filter.
Also, you don't need to change swap the needle for any reason for a different taper. The one that comes with the 606 is correct. You can adjust the needle height through, as a normal part of tuning. Google it
and be prepared to do your homework
to get everything dialed in!
Recommended: Solid Aluminum Intake Manifold
Commonly called the "30mm intake", this little beauty is much more durable than the original rubber manifolds. Since it is made of solid aluminum, you will not run into dryrotting or cracks in the manifold body over time like with the original pieces. This larger manifold is higher flowing, and is required for use with the VM26 carburetor.
This carburetor comes from the factory with 190 Main Jet and 22.5 Pilot Jet. This will work for a 185cc - 190cc big bore engine, however is too large for a 150cc engine. Depending on your elevation you will want something more in the range of 140 - 160 main and 15 - 20 pilot.
Your cable end will need to be rounded down
Your original cable will need to be modified to work with this carburetor. The end-ball will need to be rounded down to fit into the slot of the carburetor.
