Connecting Vacume Spiggots.. will it work?

[0l0dom0l0]

So I have heard if you are after a bit more grunt at the bottom end, you can connect the vacuum spigots of cylinders 1+4, and 2+3 together, and i assume it means the engine draws more fuel and air through at low rpms to provide a little more torque and power i guess?

Now my question...

If i connect all 4 vacuum spigots together is this going to improve the performance considerably?

i would like to point out my bike has a 33bhp kit fitted, which is the washers between the cabs and the engine, and will doing this mod help reduce the affects of the kit? at the moment the bike revs out at about 8k, unless you are very careful with the throttle.

help much appreciated.

thanks
