i dont think it gives you any power it does remove about a 5lb weight though.
its worth it if you have aftermarket exhaust because it stops the popping through the exhaust.
 
The "suck' mod relieves crank case pressure by putting a "vacume" on the cases to cut down on co-efficient drag on internal parts-crank,trans,etc. This helps in high RPM situations.Some dragbikes even go to the extreme of running a vacume pump on their cases.
Removing the pair valve is not really a "big" performance mod.saves a little weight,eliminates deceleration popping on a properly tuned bike.
 
I have seen it add up to 3hp, usually only 1 or 2 tho.
However, it may, and HAS caused people's oil light to flicker, because it's sucking oil away from the pickup.
Mine did it.

I personally wouldn't use the mod.
Take it off and chunk it.
 
After i did mine, it did seem more responsive. If you do not have a full system exhaust, wait and do it all at once!
