air box modification for 99 summit x

just wondering if anyone could me advise on how to modify the air box on my 99 summit x. I read in one of my snowmobile magazines that it was possible to squeeze a few more ponies out by doing this. any advice would be appreciated.

Xray--I didn't do mine myself--I had Weller Recreation in Utah do mine but it is well worth the effort or $ which ever you choose. It mainly consists of drilling 4 1" holes on the sided of the main vent and going up a size or 2 on your jets. Sorry I don't have the exact size but in last fall's Snowwest I believe it had the setup when they ran the RMK's and X's together set up from the different dealers--Weller's was the one that ran the best in the tests. For what it's worth.

The to Summit X's in the Snowest dealer shootout posted very close results, but I believe they actually gave the "King of the Hill" title to Tom's Snowmobile Service. Not that that classification from Snowest means anything. If you reviewed the specification tables it is pretty apparent that Snowest mixed up the modifications that Weller and Tom had performed.

Since you also from Alaska, you might get a more useful calibration from Tom who is located in CA and may deal with riders from lower altitudes more often than Weller who is in Utah.

Tom sells widening kits and Fox shocks too. He can be reached at 530-862-1128.
