I have used K&N filters on all my EFI vehicles. It's pretty simple. Hook up the battery after installation and start her up. EFI re-maps itself. No brainer.

I've never installed a K&N on a carburated anything. Is there goin to be any re-jet issues?

Edit: Did use them on my '77 RM250. Unmodified. no porting and polishing. No issues then. no issues now?

 

Yes, or maybe no.
Carb bikes have no idea about remapping, they think it's a GPS function. Depending on how far away you are from the standard fitment you may, or may not give yourself issues.

Are you talking about a direct K&N replacement for the factory filter or are you looking at a pod filter set-up?

 

All K&N's on mine - stock replacement types not pods - no adjustments or jetting done

 

@ Kiwi. Just a stock replacement for the current factory one. No pods

@ Sprock. Thanks

 

I have a K&N on mine, no jetting done neither, runs perfect.

 

Yep a year with K&N on mine too, no problems.

Have one in my 89. Pulls like a freight train and I've never touched it.

 

The votes are in. Looks like I'm buying one

 

I just bought one and this was the best price I could find anywhere
