RG500 Air Filter Comparison Overview

I did a dyno shoot out of sorts with my gamma and a long hill.  Wound three filters and open carbs up that hill WFO in 3^rd, comparing acceleration and how far it would rev.  I experimented with various sizes of mains and three different pilot jet sizes.

It was two long afternoons.  I am really good at changing Gamma jets now.

Big jets that made the rg500.com filters unrideable, and made the original Lance Gamma filters stumble a bit, made the bike very perky and strong with the TriPods. 

There was no difference between the jets I could get the TriPods to take and what I could get open carbs to take.

If the filters allow richer jetting without four-stroking then they have demonstrated they are flowing more air. 

My results are that the TriPods allow as rich jetting as open carbs.  Including going up two sizes on the pilot, which is really good for getting a corner exit drive started.

As Kenny Roberts said “Burn more gasoline, make more power.”

Epilog:  While doing this filter test I spent two afternoons running up the same hill three or four times every forty-five minutes or so.  Skaggs Springs Road just West of "The Bridge".  The mufflers on my expansion chambers hadn't been repacked in several years, so they were very loud.  When I was done the second day I headed back to town.  I was feeling rowdy and riding at Full Speed.

Came around a corner with a good 3rd gear drive going only to see two CHP bikes headed the opposite direction.  The second was about forty yards behind the other one.  It was way to late for me to slow down for them, so I decided this was a Good Time to split the scene.

I kept it WFO, shifted to 4th and zipped past them.  The first made no visible reaction.  The second weaved visibly in shock at my approach.  Stopping would force them to give me a very expensive ticket.  Continuing on about my business would allow them to show the citizens they flushed the noise maker away, while saving me a ton of money.

So that's what I did.
