Your cart is empty.Installing a jet kit in your carb is the best way to get the maximum performance and longest life out of your bike. The stock carburetor from the factory is designed to meet Import Regulations ... not peak performance. Once you install or modify an exhaust or intake, you have put your bike into a leaner condition that will eventually destroy your engine due to heat from running lean. If you notice any popping, you are extremely lean. Our jet kit provides the parts and installation instructions to enrich all the circuits in the carb, to fix this problem, and add performance you can feel in the seat. This is a comprehensive jet kit, addressing all throttle positions, throttle response, and each kit is custom made to your bike and its modifications. Replacing just the jets does not address 1/4-3/4 throttle position, or throttle response, only full throttle. 1 KIT IS FOR THE ENTIRE BIKE, ALL CARBS ON THE BIKE. Benefits: More Peak Horse Power - (Designed to gain 6%-8% in HP with intake/exhaust, 2-3% on bone stock.) Longer Engine Life- (The jet kit is a performance upgrade that allows the engine to run cooler which increases engine component life.) Increased Performance- (Designed to improve all RPM ranges of performance and throttle response.) Lower EGT's (exhaust gas temperatures) If you have installed an aftermarket, or modified the stock exhaust or intake, this is needed or you will damage your engine. Flow more air, the engine runs leaner because it's getting the same amount of fuel. Running lean causes detonation and hotter EGT's which ruin exhaust valves and destroy engines. Kit Includes: Main Jets, Needle Adjusters, Nylon Spacers, Drill Bits for: Slide Hole Mod, Slide Spring Mod, Idle Mixture Mod, Bike Specs, Carb Schematic, Carb Synchronizer Tool (how to build for $5), Step by step instructions customized to your bike.

Very good kit....the bike makes a lot more power at all rpm. I went from a 16 to a15 tooth front sprocket before the carb rework and if you were in 5 gear under 60 Km the little thumper struggled....now after the carb rework it pulls 5 gear better now than before the gear change and will now hit 115 Kmh on flat ground where as before the gearing and carb work it it had trouble hitting 100 Kmh....I'm having trouble not ordering the nitrous kit lol.

I couldn't be bothered to install it myself so I can't comment on how easy it was to do it but it definitely changed my GZ to the best. This and changing the front sprocket for a 16 t one were among the best things I did on my motorcycle. You could probably buy all the pieces separately to do this cheaper but it is so much more convenient to just get this great kit. Would buy again.
