Follow Setup Installation Instructions If you find any errors, or would like to add in any way please let me know, thanks! This is a basic throttle kit for the Predator cc. The governor will not be affected by this. Assemble the kit as shown. When threading the bolts in, move your wrench or ratchet in either direction a few times, this should make the threading easier. Start by removing the air box assembly, remove the tube from the gas tank. Remove with a 10mm socket the two nuts holding the air box assembly on. Slowly pull it away – there may be another hose in the back. This is what it should look like: Now ready to prep the stock linkage for the upgraded kit.

Between the tank and carburetor How to Check Small Engine Fuel Pumps On a normally operating fuel pump, there should be no gasoline present external of the pump or in the pulse line. If there is fuel present in these locations, or if the pump is simply providing fuel to the engine, then follow the steps below to inspect and replace the pump. Turn off the fuel valve if equipped at the base of the tank where the fuel line is attached. If there is no fuel valve, stop the flow of gas using a fuel line clamp.

Predator cc Performance If you came to this page you are probably looking for a go kart engine or a predator cc engine, you are in luck. I have been upgrading and building go karts for years and have some engine buying advice for the racer, or novice yard kart driver. Go kart engines can be used for racing or just putting around the yard depending on what performance parts or mods that you upgrade. There are many small industrial 4 stroke engines you can use, but who cares about them.

Lets skip all those, and just go straight to the cheapest, and very reliable go kart engine: Predator Engines Predator engines have destroyed the competition. Because they are so inexpensive, predator engines have opened a whole new world to go karters.

The Customer Question gas seems to be under The gas seems to be under pressure going to the carburetor. It a continues flow out of the over flow tube. Kinked the tube to stop the gas flow and gas is in the crank now.

 · Place the new carburetor flange gasket, provided with the carburetor, in the proper position on the intake manifold. 3. Place the carburetor on top of the flange gasket on the manifold. Install the hold down nuts and snug down progressively in a “crisscross” pattern ( in./lbs.), as shown in Figure

Our Mikuni fuel pump is simple, easy to install and operates off the the pulse created by the engine. There are many different locations to mount the fuel pump. One thing you want to keep in mind is the fuel pump should be as close as possible to the source of the pulse which runs the pump. The fuel pump pictured has been mounted on the fan shroud.

Once the pump is mounted you have three lines to hook up. The fuel line on the right is coming from the gas tank and going into the inlet on the fuel pump. The fuel line on the left is coming out of the outlet and going into the carburetor. The fuel line in the center is the pulse line that runs the fuel pump. We drilled and tapped a hole in the engine side cover and installed a pulse fitting. A pulse fitting is nothing more than a brass fitting you can find in your home improvement store’s plumbing department.

Pretty new to Polaris for that matter. But now I have an ’05 Predator and it’s driving me insane. It’s super clean and not really modded up. Actually it looks all bone-stock save for the Yoshi exhaust can. So here’s what it’s doing It’ll start up very nicely.

 · The Predator is capable of flowing up to c.f.m.; but works strictly off of the air demand of the engine and met ers the fuel in carburetor to be turned 90 ˜ and still maintain the standard linkage hook -up. This will allow the bowl to be mounted to the front (Part #) or the rear On multiple carb set -ups: All carbs are

Remove front fenders, then gas tank, and airbox assembly. This gives you access to the top of the motor and the throttle cable. At this time remove the stock thumb throttle and disconnect the wiring from the throttle. With that disconnected you can now remove it since you will not need it. With the thumb throttle assembly off and throttle cable removed from the thumb throttle assembly you can move on to the gas line. Using a pair of pliers, slide back the retain and pull off carb.

What is on second. Yes, What is playing second base. So try this one. A dude hits a single, a double, a triple and a home run. But he hits a single, double, triple and a jack?

Predator’s front suspension allows the rider to stay on the gas in corners instead of backing off to let the quad resettle and hook up again. To deliver this performance, the Anti-Dive Front Suspension minimizes dive and inside rear wheel lift when the rider is braking in ://

The following hardware was used for the complete throttle assembly from the pedal to the engine: Gas Pedal The go kart throttle pedal also known as a gas pedal is the one on the right of the picture with its associated return spring and hardware used to mount it to the go kart frame. Looking at the gas pedal, you will notice there are four small holes on the lower portion of the pedal.

that hose goes to the those little barbs on each side of your carb just above the throat. there is supposed to be one for each side. they are vent

These Polaris Predator 50 racing series spark plugs are designed to help you improve power output, low-end torque, take-off time and acceleration to further increase fuel efficacy. Our UTV Polaris Predator 50 high-performance plugs’ design ensures optimum mix ignition in the cylinders and warrants extra performance potential compared to traditional projective tip spark plugs and other brand fourwheeler performance plugs.

The degree electrode Polaris Predator 50 plugs outperform even the iridium sparkplugs in regards to firing energy, extra output as well as reliability. Because the sparkplug gap is not shielded by the conventional side electrode, exposing the mixture to physically unlimited ignition, combustion speed will increase and flame front spread can take place more easily, and especially more quickly.

Easy engine start is attributed to this effect. The subsequent increase in medium effective pressure within the engine cylinder also contributes to added engine performance capability and optimum four-wheeler fuel efficiency. These Polaris Predator 50 multi-spark sparkplugs are made for extreme operating conditions and high output; there is simply no competition for the Brisk degree sparkplugs.

Unlike regular spark plugs, where discharge is constrained by the ground electrode, Brisk Polaris Predator 50 high-performance sparkplugs feature an electrode layout where the ground electrode is retracted, so the spark discharge occurs at the very tip of the spark plug. Traditional spark plugs’ ground electrodes restricts the natural spherical expansion pattern of the flame front whereas our High Performance Polaris Predator 50 plugs take the advantage of surface spark discharge, along with retracted ground electrode designed, to ensure maximum spark exposure and unrestricted flame front expansion.

Due to stronger spark discharge, a spark can more easily trail along the surface of the insulator than having to break through the air gap.

Basic Carburetor Tuning Guide First off, there’s 2 basic fuel related problems. You either have a rich mixture, or a lean mixture. A rich mixture is caused by too much fuel compared to the amount of air being used during combustion. Rich conditions can be detected by the engine spitting and sputtering, blurbling, or acting like a rev limiter, rapidly losing and regaining power. In severely rich conditions, you may be seeing black smoke coming from the exhaust.

The black smoke you see is actually raw fuel that is not being burnt and is being wasted. By looking at the spark plug, a rich condition can be detected by a black, sooty plug. A lean mixture is caused by too little fuel compared to the amount of air being used during combustion. Lean conditions can be detected by the engine losing power, yet retaining it’s engine speed. For instance, the engine sounds to be accelerating to higher RPMs, yet feels as if it has no power.

By looking at the spark plug, a lean condition can be detected by a white, blistered plug.

What kind of carburetor for a polaris snowmobile

I love the carb but there always seemed to have a idle problem. I tried many different pilot jet sizes and seemed to have a way smaller one then most of you. When I got my back from rebuild last month It just didn’t seem as fast as it once did and after taking my modded motor out of the frame set up,the got way faster. I put the motor in a stock frame with stock carb,stck fuel pump ,stock cdi,and the pp polaris pipe. The thing got speedy and I have no idea why but It did idle way better,then it did with all my parts Dyna cdi,rath full pipe,fcr 41 carb So yesterday I tried the stock fuel pump on the with the fcr 41mm.

 · Mikuni carb throttle cable hookup I just got my carb for my predator and I hook the throttle cable up and and it only has a very short travel on the throttle now I’m using the stock doodlebug throttle assembly and cable, I think that the end of the cable that goes into the carb might be too long because I’m about 99% sure I hooked it up

The innerwire length is shown above. Eyelet on one end, straight wire on the other. Make sure the throttle pedal is against the rear pedal stop 3. Pull the throttle cable housing toward the rear of the kart until you feel resistance. DO NOT pull the throttle cable housing any further. Hold the cable housing in this position and screw the front jam nut 2 against the frame. Pulling the housing past the first point of resistance will engage the engine throttle while the throttle pedal is in the idle position.

Upon starting the engine, the vehicle may accelerate. Screw the rear jam nut 1 against the frame. Tighten the front jam nut 2 securely. Make sure the engine throttle linkage is in the idle position and the throttle pedal is against the rear stop.
