Has anyone tried putting K&N filters on the fuel injected RXL motor?

If so:
What did you do with the diode sensor that screws to the side of the air box?

Did you have to re-calibrate it for the increased air flow? If so, how do you do this?

I know they won't add performance, but they'd free up a lot of space in the engine bay and they'd look pretty cool.

Thanks

At what price? The heck with what they cost. You should hear how loud they are!
20 miles and you'll be wanting the air box back....

the K&N's will reduce hp numbers. rework your stock airbox. but if your set on the filters, build a rear support for the throttle bodies. if you don't the intake boots will rip in a matter of days. the loss of hp comes from ingesting hot air instead of cold outside air. other problems are the filters rubbing on the jackshaft and creating holes for lots of belt dust to sucked into the motor.

Any experience with this happening, just curious.

He is correct about reduced HP with K&N because of higher intake temps. Again, this wasn't about performance, it was a style choice. The deal killer is the fuel injection computer on the RXL isn't programmable, so if I did this swap, the motor would grenade in short order. Unfortunately, that's one of the drawbacks to the RXL and one the reasons I decided to part out this sled rather than pursue doing anything with it.

unfortunately i have plenty of not so fond memories getting several buddies' RXLs off the mountain. they all tried the filters, and they blew them up from ripped boots and/or misreading sensor. i also have experience with the 600/650 Fugi carbed triples that have done the filter attempt. the boots get ripped or the carbs pop out on big bumps. if you carb an RXL and advance the timing a couple degrees it will rip nicely compared to a normal 650, they did a good job on the ports.
