*Components vary by product.Please refer to the product image. *This product is for one carburetor (for one cylinder).
Keyster's Carburetor Tune-Up Kit includes almost all the parts needed to repair or adjust your carburetor.Needle valves, idle screws (air screws), float chamber gaskets, etc., but the most distinctive feature is the wide variety of fuel control parts.There are 3 sizes of pilot jets, 6 sizes of main jets and 4 sizes of jet needles. The rubber needle valve is made of "AA Needle" which is the super needle that won the invention prize.Its amazing performance far surpasses that of stock products. Conventional jet sets for tune-up are distributed equally in size.For example, it skips by 5 or 10.But the jetsets in the fuel tune kit are not evenly spaced.In combination with the jet needle, the size is designed to change the air-fuel ratio effectively and precisely.
The first use of the fuel tune kit is for troubleshooting.For use to repair motorcycles with fuel supply problems. The basic direction is that the pilot jet, the jet needle and the main jet should all be moved in the L direction to increase the A / F ratio, and all of them should be moved in the R direction to decrease the A / F ratio.However, the combination of L, S, and R will be different depending on how you want to change the range of low, medium, and high speed.This is one of the best parts of carburetor tuning.
Another application of the fuel tuning kit is to tune up the motorcycle (performance improvement). However, the carburetor is not a device that generates power by itself, so no matter how much you adjust the carburetor, the effect of tuning up is not expected.Please note that the performance will be improved by adjusting the carburetor to fit the engine and the parts of the engine front and rear when they are replaced and tuned up.For example, if you try to improve the performance of the engine by changing the air filter to increase the amount of air passage or the exhaust to reduce the exhaust resistance, the mixture conditions required by the engine will naturally be different.This is where carburetor adjustment comes in.This can be easily met with a fuel adjustment kit.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
[How is it used? TZr250R (3XV1) I bought it for. There is another one for 3XV1, but that one wasn't in stock and Jet's count was different, so I bought this one. I cleaned the carburetor of a car that hadn't been used for several years, but it was overflowing, so I replaced the jets as well as refreshing the carburetor.
Was the one you received as per Image? There are three more cases inside the case, and the small jets are properly divided into small ones.
Was the installation difficult? Only the Main jet of the Right Sidecarburetor does not have the same hand as the OEM of the 3XV1, but other than that, no problems at all. Also, in the Instruction Manual, the main nozzle is supposed to be entered from the bottom, but it is actually entered from the top.
How was your experience with it? The engine was very difficult to start with just cleaning, but after using this product, it started with a single kick. Overflow is cured and Idling is stable, so there is nothing to say. One disappointing point was that the Top cover gasket on the front side had the one on the back side.
【Review】 I had no problems with the accuracy of the parts, the functionality, etc. As of February 2022, OEM parts for the 3XV Needle Valve will still be available, but they will cost $5,401 per side, so if you think about it, this product seems cheap. The top cover gasket on the front side was wrong, but other than that, I am satisfied.View Detail
Obtained vehicle (3XV4) He was concerned about deterioration of Jet due to Tank being rusted, Quantity : Pair (for Left and Right) I also used it together. I heard rumors that the key Star's Jet kind is slightly erroneous when it is Mikuni type carburetor, but there was not any problem at all.
OEM count + DFRStainless Steel Chamber lightly dandruff like lying from around 3750 rpm.
Even if putting the OEM count of this kit after cleaning, if dandruff is bad, please doubt the power jet. Our car was clogged severely.View Detail
