hmm thanks for the info! what are the plus's of getting a shee petcock?

The blaster petcock has a 3/16 end for the fuel line, and the shee petcock has a 5/16 fuel line end.

My 36mm pwk has a 1/4 inlet, so i stretch the 1/4 fuel line to fit the shee petcock.

If i used the blaster petcock i would use 3/16 fuel line and stretch the 3/16 fuel line to fit 36mm pwk.
 
yea i see that but will it actually add power or what??

Absolutly no power will be gained, and I see no reason at all to be using one to get more fuel flow to the carby.

Yes more fuel will flow if you are feeding 2 carbs, but the needle and seat assembly on a single carb will never use the extra flow available.

If you want evidence of this just look at the size of the orifice that the needle blocks off, it is pretty darn small it will never be able to accomodate even the full flow of a Blaster petcock.

The benefits lay in the size matching of the feeder tubes of different carbys.
 
If you have a modded motor that is built to run a bigger carb and that bigger carb is designed with a 1/4 inlet then you want a 1/4 fuel line, and that 1/4 fuel line is going to want a 1/4 petcock... And the cheapest petcock i could find that will fit is a banshee petcock, and its a 5/16 petcock. It may be overkill but its better to be overkill then underkill...8-|
