Uni Filter Observation. Started Greasing the edge.

Recommended Posts

I've been running a Uni Filter for about 30K miles. I've ALWAYS had dust passing the filter. NoToil oil.

So for an experiment (for the last 1200 miles) I put alot of NoToil rim grease on the edge of the filter and the edge of air box.

What I noticed now is that my bike is running very rich(the plug looks ok but the end of my HRC exhaust tip used to be toasty brown and is now black) and my mileage went from 32 mpg to 25 mpg.

Am I finally getting a good seal and that's why the mileage has gone down or is something else happening?

Maybe continue with the grease and drop the main jet a size?

You weren't greasing the sealing edge until now? :moon: It must have been sealing pretty badly if it affected the jetting. Speaking of which, what jetting do you have? And what bike?

You are getting a better seal now if there's no dust passing by the filter.

So you may need to go a little leaner somewhere as well.

Ride and test and see.

Leaning out your jetting to an appropriate level will get you some of your MPG back. When I used to run old Mopars down the 1/4 mile, I always had to tweak my jetting when I dropped the mufflers and pulled off the air filter. Makes sense that the same reasoning would apply to a bike.
