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.

High cost performance, and fun setting... maybe!
I used it to wake up a friend of mine's DF200 DJEBEL, 4 years old!
Fortunately, the fuel in the carburetor and tank had been completely drained when the car was put into hibernation, so there was no internal corrosion.
I've gone to a lot of trouble to make sure that the key Star Quantity:Since we had purchased a set, we replaced the parts that could be changed, and the carburetor body was thoroughly inspected and cleaned.
As a result, the Engine started up perfectly.
Needle valve set (Float valveassy) +&alpha. when bought together with OEM Parts;
You can only buy about PJ, MJ, and JN, which can be swung even thicker or thinner, are the various Quantities:It is also nice to be Set.
In this case, we assembled the OEM's number for a full normal body.
The machining accuracy is as good as its reputation.
The Brand logo is cute. (I think Sticker used to be bundled …)
The Jet engraving is Smaller than OEM, but easy to read. I can't read it with my naked eye anymore, so I'm sweating with my phone zoomed in Large.
⇒ Spec. changes due to year, etc.? You should check the number of Jet you removed.
The material or finish of the Main nozzle and Needle is different from OEMMikuni. If you don't mind, it's OK.
The filter design on the Needle Valve is a bit different.

I used to be a mechanic for a motorcycle dealer and have done carburetor OH countless times.
Let me speak a bit from that experience. ↓
One example of many DIYcarburetor cleaning failures is Case, which completes the Overhaul with only Jet-related cleaning.
In fact, there are not only the Jet, but also the Idol port, the main nozzle, the Starter system fuel passage, the small passages around the air screw or Pilot screw, the O-ring, the diaphragm of the air cut valve, and many other small and important passages. By understanding the structure of the carburetor and cleaning each passage completely, a perfect carburetor can be made.
It is also important to check the oil level. If the oil level is low, it will be thin like when you are about to run out of gas, and if the oil level is high, it will be thick, increasing the risk of overflow.
I think it's fun and good to repeat the experience over and over again to improve your skills, but it's not a good idea.
The fuel system is deep and difficult, so if you are not confident about the carburetor's Overflow, it may be better to consult a trusted Shop.

Recommendation for those who use OEMcarburetor.

All this for such a great price!
Purchased a used car with KSR80Chamber on Yahoo!
Since the carburetor has been overflowing, we wanted to do maintenance, including setting, with other manufacturers, so we purchased this product, which contains multiple Jets.
After adjusting the carburetor, the overflow was fixed and I am enjoying my commute to work and touring in the neighborhood.

I was asked by a friend to set up an RZ with an external chamber.
Was the one you received as per Image?
Yes
Was the installation difficult?
No problems
