2006 CRF250R Jetting Help with aftermarket parts

Recommended Posts

Hi three quick qestions..

1. How does a Loudmouth intake system effect the jetting on my bike?

2. How does a Power Now System effect the jetting on my bike?

3. How would the jetting be effected if both were on my bike at the same time?

Thanks for any advise!! :smirk:

1) maybe slightly leaner if the bore is larger than your current intake. The loudmouth primarily gives you a better seal for your filter.

2) It doesn't.

3) You might need to richen the jetting slightly. Then again, you may not.

Please, do not buy into the marketing hype about the loudmouth. It does offer a batter seal like David said and people say it is easier to remove the air filter. The Hp claims are total BS. The chance of it making any difference on your jetting is slim unless you have done a lot of other modifications to your bike and are now finally doing the air filter/airbox.

The powernow masks/hides jetting issues. It actually reduces your top end as you are inserting a restriction in to the airstream. Please, do not buy it and if you did, return it.
