'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 not just some jets in a bag, it 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, or throttle response, only full throttle. This Kit is for all throttle positions, and throttle response.

Please let us know year, exact model, level of modification, and altitude, so we can tailor our kit to the needs of your bike. All of these factors affect kit design.

Please add your information when you check out.

1 KIT IS FOR THE ENTIRE BIKE, ALL CARBS ON THE BIKE.



Benefits

More Peak Horse Power
Designed to gain about 8%-10% in HP with intake/exhaust, 3-4% on bone stock.

Longer Engine Life
The jet kit is a performance upgrade that not only increases power, but 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.
