Probably a dumb question but...

What the hell is PAIR and how does removal effect performance and ability to pass road inspection?

They're the little tubes that connect to the front of the cylinders under the exhaust ports. They're supposed to introduce some fresh air into the exhaust port to promote the burning of any excess fuel in the exhaust gases. It's an 'anti-pollution' thing.....

Not sure which states actually check for removal of OEM pollution devices. Holeshot does sell a 'pair block off kit'.

That's what made me ask...saw the removal things at HoleShot. THanks, Pete.

I don't think it has any effect on perfomance or emissions (maybe a little). It does reduce weight, clear up some clutter under the tank and make maintenanve easier.

Check the FAQ on this board for a PAIR Removal DIY sections I posted. No need for the Holeshot kit.

Bill, like the pipe- she would sure look good with a set of clip-ons.

The Holeshot kit is worth the money, the block off plates are nicely machined and come with gaskets. I did mine just to get rid of the extra plumbing and hassle of it being in the way for maintence. Removal weight is not really a factor on a 500lb bike. You could diet for a week and lose more than PAIR weighs.

The PAIR valve is about the size of a small fist, is mounted to the frame underneath the tank, and does get in the way when changing plugs and checking valve clearance. PAIR removal is simple, once the tank is off, about a 30 minute job.

Thanks guys. Understand better now.....something else added to the list. Incredible how they clutter up simplicity, these engineers, huh?

Ed. YES....methinks the clipons are soon to be.

To make it easier to do a valve adjustment I removed the PAIR control valve and plugged the four lines going to the exhaust ports and the vacuum line doming from the 4th carburetor.

It saves a little time and fiddling when doing the valve adjustment, and the lines are still there in case the next owner wants to hook the system back up.
