Stage 1 is for motorcycles with stock engine and with stock air intake and stock exhaust system.
Modifications to the air intake and/or Exhaust system to your motorcycle will change the air/fuel mixture to your carburetors causing a lean running condition.
Jet Kits will compensate for the lean running condition.
Lean running conditions can destroy your engine and decreases overall performance.
Jet kits are easy to install but does require some basic carburetor tuning knowledge.
Refer to your shop manual for carburetor removal and jet installation.
This is only jetting suggestions for your application.
These are recommendations only, based upon testing at sea-level atmospheric pressure,
a 65-80F degree ambient air temperature,
on super unleaded pump fuel with a stock motor.
There are too many variables outside of our control to give you an exact configuration that works perfectly under all conditions.
Our recommendations are just that, a starting point to reference from.
Higher elevations, high humidity, hotter temperatures are examples that will require leaner jetting.
Colder temperatures are an example that will require richer jetting.
If you are not knowledgeable or don’t feel comfortable tuning your machine yourself, find a mechanic in your area who is.
We are not responsible for problems derived from improper jetting and/or usage.
Always check that your jetting is correct when changing parts that could affect the intake system, exhaust system and any product or change
that could alter fuel combustion in the cylinder.
