Joe, there are no K&N's for the stock air box, however if you kept your old air cleaner elements you can cut the old paper out and put in K&N material or Foam material to make them reuseable. I've got a set I'm working on putting K&N material in, but since we moved I haven't gotten back to that project yet. There was also a post in the past (Bob Taylor I think) about using foam material. I'll see if I can find it and send to you direct. my .02...Bob B. -----Original Message----- From: Loss, Joe [mailto:[EMAIL PROTECTED]] Sent: Monday, October 04, 1999 10:44 AM To: Multiple recipients of list Subject: RE: GTS at altitude (fwd) The air filter issue has me interested, cos I just reluctantly forked out about $80 for a set of OEM filters. I gathered from a previous post the K&N's you guys have fitted allow you to ditch the air box completely. If I remember correctly the air box has a sensor (air pressure/temp/?) for the EFI. If that's the case, it wouldn't surpise me it didn't run right. Do K&N make filters to replace the OEM filter units? ie; retaining the airbox?

While I ran the K&N's during the Utah rally and had no problems at altitude, it really didn't seem much better than stock (I have a '93 with low miles). A fellow GTS'er I met at the Utah event, tried the K&N's on his '94 when he got back and said it ran like crap - had a flat spot, lost 10 mph off top speed. He has ~ 50k+ miles on his engine. '94's are supposed to run richer than '93's and with a tired engine, we theorize that the K&N's made the bike run richer so much so that the EFI couldn't adjust for it - it only has certain ranges within it's preprogrammed map. That's why K&N and others are coming out with these EFI reprogrammers. At higher altitude, thinner air, if you're already on the rich side, then would only get worse. Do you also have a '94 and lot of miles on the engine? -- Dave Biasotti // Fremont, CA George Paramithas wrote: > > Yea me says altitude and GTSs don't play well together.
