pair valve

Ok, what is the advantage of removing the pair valve??

You loose a small amount of weight, and if your bike is backfiring on decelleration it usually fixes that problem.

Other than that, nothing. There is no performance gain by removing it.

What wingspan said, plus.. just less un-needed crap on your bike.

It's amazing how much crap I strip off a bike when I first get it. (Safety and smog and etc...) I really want a motor a frame and the basics to make it all work SIMPLE like...

So for me the nice thing was just getting rid of more crap, the front cylinder looks better, plus next time you take the tank off or TPS or whatever you got one less thing to worry about.

Being that I am no mechanic, should I attempt this? If I have a detailed set of instructions with pic I know I could do it. My TL1000R backfires horribly. When my buddy rides behind me he says it sounds like a gun going off in his ear.

Anybody can do it.. It's a little harder on the "R" i've heard though.. Remove the steel, the valve and block off everything..

One thing that made it real easy for me was I bought a set of those Gearwrenches.. Small enough to get back in the little spot and get those nuts off.

Make sure you order (or make) block off plates before you start pulling anything apart though!

If you go block off plate route it is a pain on the rear cyclinder. Removing the rear header is a minimum. I removed both rear sets, damper, header, clutch slave and sprocket cover. The front one is a breeze. All together it took me about four hours of work for the block plates. This was just taking the hard lines off and installing blockoff plates.

You may want to invest in a gear wrench for the rear one , its hard to get to check them out here http://www.toolsource.com/ost1/resul...OVMTC=standard

I bought the block off plates from Krisnett. (He's the guy to get it from if you are going that route, great product fast shipping).

Then while looking at the service manual to see how to go about removing the pair valve (Krisnett's instruction sheet is good enough if you don't have a service manual), I decided I could make use of the PV rather than removing it.

We have a piss poor crankcase ventilation system. So what I did was:

- Buy a Y-joint for garden hoses from the local hardware store

- Locate the hose coming from the breather catch tank to the airbox, disconnect it at the airbox, connect to the Y-joint. (cap the hole at the airbox using those round rubbers covers for chair legs)

- Locate the hose coming from the PV going to the airbox, disconnect it at the airbox, connect to the Y-joint. (cap the hole at the airbox using those round rubbers covers for chair legs)

- The final joint at the Y-joint, run a hose to the rear fender, plug it with a mini K&N filter.

The PV now acts as a positive crankcase ventilator. Sucking the oil vapors from the crankcase and injecting it to be burnt off in the exhaust. The crankcase is happier, the air in the airbox is cleaner.

The hose to the rear fender simply acts as a inlet ventilation for the crankcase when everything cools down.
