Let's talk about functionality now for a moment. Well, this high-performance VM22 carb is more capable of delivering high-end tuneability. Therefore, making adjustments and customization will be more liberal. Dynojet stage 1 kit, original airbox&filter, Mivv slipon muffler, new sparkplugs, pilot screw: 2,5 rounds Who should grab this one? Well, the Nibbi 26mm carburetor does not remain with those units that require only a simple bolt-on installation without any sort of modifications. If you are someone who would love to get the best experience by modifying or customizing the tuneability in a different setting, this one is a must-have item. Another reason you might think about going with this item is its easier installation. The availability of every necessary item and hardware simply will allow you to install the kit within a few minutes. the exhaust had very small baffles in which I have replaced with 8inch baffles and baffle wrap ( makes chuffing sound now instead of loud bang) apparently the previous owner had a Dyna jet carb kit fitted at same time, carb sync looks near enough, neither mixture screw has much effect, front is 3 turns out and rear is 2 2/3 out popping seems to ease a little if front mixture screw screwed in until it is 1 1/5 turns out but neither effect engine revs, when the front mixture screw is fully seated with engine running then loosen it engine revs rise slightly but only momentarily then even out again. spark plugs good colour not sooted up or white. thought I had a vacuume leak sprayed carb cleaner on rubber carb mount to engine on front cylinder, engine revs rise dramatically,, stripped it down twice now and reseated/sealed all I could,, I`m now at a bit of a loss as to what to try next.any suggestions.

Carb 1 (top) main 128, pilot 42. Carb 2 – main 112, pilot 45. Carb 3 – main 128, pilot 42. Carb 4 – main 112, pilot 45. By controlling the width of the venturi, the volume of air and fuel mixture transferred to the intake manifold is controlled. This amount of air and fuel mixture sent to the intake manifold also controls the rpm of your pit bike.

CARB ONLY

Around 60% of the users have loved this item by giving it a whole five-star. Around 20% gave it a four start. Most of them were not happy about the shipment. Some of the users indeed gave it three and two. Who does not love to rely on the carburetor unit to boost the performance of the engine? This 26mm carb unit should bring satisfaction in every scenario to keep the users happy. What about the performance and speed gain? Well, the proportionate construction should deliver better RPM and speed to maximize the performance capacity of your pit bike.

Once you install this carburetor to your pit bike, you will notice a dramatic improvement to the choke and throttle control capacity. Besides, getting the optimum amount of throttle response will be easier than ever before. These are not the least things you can expect to get from this item.Grab this one from Nibbi and let the world know that you are someone special when you are on your pit bike or motorcycle.

How about getting a more racing vibe from your pit bike engine ? If that is your concern, this one from Nibbi has been satisfying the users for a long time.With all the changes, the bike transformed in attitude…great throttle response, and it just sounds mean!… Only thing is, I’d like to get it dialed in nice. It’s a little over poppy on the decel…( I expect some ) and the fuel mixture screw can be all the way seated and it doesn’t slow down idle. It's not the price that defines the quality. When it comes to functionality and reliability, this 26mm carburetor will always be on the good side. Therefore, grab this one to make you more comfortable with your riding. Re-jetting might be an ideal solution to get the performance and reliability you expect from the item. In the inception, this carb runs on a 95 main jet. Upgrading the main jet from 95 to around 120 should allow you to ride on your toy with more freedom. Do you think this fuel consumption increase is normal? Can I normalize it through only set the pilot screw?

I have a Virago 535 2002 with popping from front cylinder, Bike has Highway Hawk Fat Pipes ( think they are highway hawk, no marking on them) The thing we love most about this carb is its high-end tuneability. Having five different needle options always allows the rider to tune the setting in different moods to have the most convenient performance. Last but not the least, this one is compatible with a large number of Powersports. Therefore, you will always have the authenticity to use it in multiple applications. I had a 180 MJ, 52 PJ, and N3EW needle in centre notch. Running 40:1, and the Air screw was about just over 2 3/4 out, so it’s a jetted a little bit rich. (I think) Bike pulled well, no real issues on performance just a fair amount of spooge and plugs always coming out wet (if not fouled) and fouled. By default, this Mikuni Carburetor will have a 15 pilot jet with a 95 main jet. This measurement should bring the optimum experience. But you can also think about installing a 20 pilot jet with a 112 main jet. Doing so will enhance the performance of your pit bike to a great degree.How about performance gain? VM22 is here to boost up the performance and power delivery to a great degree. After six months of usage, you will agree to the fact that this VM22 carb unit is one of the more reliable carburetor kits available on the market. Would you love to get the pleasure of a simple bolt-on installation? This Mikuni VM22 is another great item from Carbhub to give you the simplest installation experience. The bolt-on installation feature should allow you to complete the installation within a very short time. Find which bit of the throttle the bike is not running properly at, this could be anything from dying when you first open the throttle to slightly bogging at 3/4 revs. The best way I have seen to do this is to make a mark on your throttle housing and a small mark on your grip level with it, open the throttle fully and make another mark on the housing, now split the space in between the marks into four equal sections with two more marks. Now you can see which part of the throttle you are at (by looking at the mark on the grip against the throttle) when the problems occur. Here are the corresponding throttle marks to the relevant parts of the carb. If you are happy with the way your bike is running, but want to increase performance by buying a bigger carb then simply go to the next size up on the list (E.g. 125cc engine would be upgraded to a 24mm carb) generally speaking if you are using a bigger carb for the engine it will be harder to dial in. If you are not familiar with which jets are which and where the needle jet is etc then see Johnr6's how-to guide “How to service the carb and change the jets”. Before attempting to tune your carb you should always clean your carb, air filter, add fresh fuel and buy a jet kit (It is recommended by some companys to use genuine brand jets even if you are using copy carbs as the quality of the jets is very important and universal sizes are needed) The primary purpose of a carburetor is to mix fuel with the intake airflow with a perfect volume. But how does this machine complete this job? Here go some of the step-by-step processes that a carb follows to complete the job- According to Bernoulli's law, ''when air flows, the air pressure tends to be lower than the atmospheric air pressure.'' We see a great representation of this law in most motorcycle carburetors.
