Question Pod air filter vs drilled airbox ???

Looking for the best performance out of my 250 FI, Leo Vince recommends drilling 2 50mm holes on the airbox, but what works best pods or drilled airbox?

Also, can I even install a pod filter on a 250 FI

I would imagine pods but I have no experience with drilling the airbox. It seems like a drilled airbox would yield less airflow than pods so idk. Is it a full leo vince system? And yes you should be able to put pods on the FI

Cool, I found your thread that asked the same:
http://www.ninjette.org/forums/showthread.php?t=101440

What did you do with the sensors?
Do you have any pictures to help me mod mine?
Did you installed the pod straight to the throttle body? It looks like the runners are attached or part of the airbox

Thanks

Honestly, I got mine done at the service center. I'll take a few pics for you tho. I believe they tied the sensor to the frame and left it at that. Also, the filter is attached to the runners, not directly to the throttle bodies. I believe they got it out the back, by removing the wheel and pretty much stripping everything after the gas tank... lol I was considering doing it myself, but the last time I removed my under tail, I landed up breaking my rear cowl fairings.

I don't know about the FI bikes. But I would say for street riding,drilling the air box is a good thing. I would also remove the fire screen from inside the air box. That makes it easyer to remove. The snorkel can also be removed.

The only vent from the crank case is the hose nipple that comes up from the block under the air box. Most people just put a small filter on it. If you run a full system you need to block off the top of the valve cover.

On my pregen, I ran a full exhaust and an airbox that was cut open. It ran really well with one size larger main jets. It was still reliable, but had a little throatier sound, and was a little more responsive. I imagine that a full exhaust, opened airbox, and a high-flowing drop-in filter would pull and respond quite nicely.

I found on the dyno that the 0990 or pod filters kept some torque. I run wide open velocity stacks with no air filter. I is worth almost 1 hp but gives up some torque. A well desined air box should have better midrange.

Yes, the bike still for street use... If I decide to keep the airbox I'll remove the fire screen and the snorkel is being remove since day one
