I plan on keeping the foam, air filter element, and oiling it with BelRay oil.

After making these minor modifications, I would then submit the bike to Dobeck Performance for development of the EJK controller.

Incidentally, the RX3 has a nice, large airbox. Notice the spacious, unrestricted tube leading from the air box to the throttle body. Also, the foam air filter appears to be 6.25-inches square.

Without seeing the inside of the muffler it is hard to determine the restriction that it has. The outside shape looks like it would have a single bypass design.
Airbox is a nice large. The opening may be adequate. Will have to put it on the flow bench and test it. Design also looks good to remove water from intake. I am not a fan of the foam type filters. Too easy to choke the air flow with excess oil. How thick is the filter? Can find a standard K&N to drop in there if there is enough space.

I apply the minimum amount of filter oil, and I get good results from foam air filters. I don't trust K&N air filters for off road riding. Since it is easier to apply sparingly, I use No-Toil oil on the conical air filters in my Honda CRF250X and Honda XR650L. It does a very good job filtering dust and allows excellent air flow, which is superior to that allowed by conventional filter oils. However, I still prefer using BelRay filter oil for flat foam filters, since it is much easier to squeeze the flat foam and remove the excess oil. Therefore, I prefer BelRay oil for the flat foam filters employed by my Zongshen ZS200GY-2, and the Zongshen RX3. Judging from the photograph, it appears the RX3 air filter is about 1/2-inch thick.

It does look like a clean flow from the header through the midpipe. I'm betting the cat is in the muffler right where the midpipe inlet is. Both the CRF250l and TR650 had cats in the muffler just as I described. The Husky was easy to knock out the cats with an air hammer. The Honda is more complicated involving opening the can up and re-welding. That muffler looks like it weighs a ton!!

I hope you do Spud. Dobeck's little black box has been the best and most versatile performance mod I've ever put on a bike.

If the cat isn't in the header, I'd be swapping that muffler out. It's probably really heavy anyway. BTW, the large outlet might be for appearances only. I've certainly seen that before.

You have my full attention. Did you fabricate a flow bench?
Since you declined to answer my question about your RX-3 motor, perhaps you'll tell me about your flow bench.

Spud, you may remember this old thread about Pastor Jim's scooter, where I found a cat in the muffler: http://www.chinariders.net/showthread.php?t=9421

Not from Tabao. I have a Superflow SF-60 that will work great.

May I ask where you bought the motor from? Top secret?
Your personal flow bench?
