SUZUKI RM80/85 JETTING RECOMMENDATIONS
Here are our jetting suggestions for your RM80/85. We’ve spent countless hours of testing to determine which settings work best
when bolting on one of our pipes and silencers to a stock machine. These are recommendations only, based upon our testing at
sea-level atmospheric pressure, a 65-80F degree ambient air temperature, a 32:1 fuel to oil mixing ratio on super unleaded
pump fuel with a stock motor.
For some models we offer a Power Up jet kit for optimum tuning. Kits may include jets, needles and any necessary hardware
and have been developed with the assistance of Dynojet.
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 unknowledgeable or don’t feel comfortable tuning your machine yourself, find a mechanic in your area who is. FMF Racing is 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 (ie. aftermarket ignition module).
Use the following suggestions when using a FMF Fatty, Factory Fatty, Gnarly, Rev or SST exhaust pipe.
