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.

[Dnyce]

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

Pair Valve Sucker Mod Instructions??? | General Bike Related Topics

Hey fellas, I've looked all over this board and found all kinds of opinions on the pair/sucker mod, but I can't find any instructions on how to do it. I know it can't be that hard cuz there's only 2 hoses that can be screwed with from what I can tell...I currently have blockoff plates...

I had posted before about moving mine so oil wouldn't find it's way out somewhere it shouldn't, and was going to buy block-off plates.
That would require me to vent to the airbox as he said.
Good info Red.

hey guys, i was planning to do the marble mod tonight ive been reading alot about the PAIR block off and marble mod lately. I read somewhere earlier that you can re-direct the hose coming from the airbox to the crank case and this in effect would allow your engine to rotate much easier therefore...

I've done the same, only I put them on the end of a long hose up near the valve cover or airbox, to keep them from flooding with oil from wheelies or crashes, lol
