Pair Valve ?????? | Engine and Performance mods

Do you guys have a link on how to remove the pair valve? do i need to remove the exhaust? and i see that you can buy the block off plates or the whole kit with gaskets? do i need just the plates or whole kit? it is a 04 bike. Thanks Joey

Here...to answer this 16 year old question.
Pressurizing the crankcase on big cc bikes, 900ish and up, is supposedly usually good for 2 to 3 hp.
I have my '03 Gsxr1k this way, as did a few of my friends over the years.
We never saw any negative side effects, but with almost 40k on my engine, I'm curious to see if any gaskets will give up, lol

You aren't supplying that much positive pressure to blow gaskets.

That’s weird bcuz most of the dragbikes have vacuum pumps to depressurize the crankcase for more hp.

No, but with age things tire out.

An add-on to eliminate resistance, vs old school, which uses what's there for a little extra push, but is only a couple hp.

Yea it’s an add on but I was more referring to you saying you’re pressurizing the crankcase and getting a few hp, and a vacuum pump DEpressurizes for more hp. It’s Interesting
