air pressure tool???

[ny300exrider]

hey ive been having some trouble getting my tires at the same pressure and before the track opens i want them to be even so i dont jump sideways. i heard that there is a tool made specifically fo this, its like a tube with two ends that go onto the valve stems. The tube lets the air out of both tires until they are at the same air pressure making it almost like an equilibriam. Does anyone know where the heck i can find one of these because it sounds like a real good idea and would make my life alot easier.

thanks

Go to www.summitracing.com and type in "tire pressure", they have them listed starting at 30 bucks. Seems kind of a waste to me, when all you have to do is air them up one at a time and check the pressure. Once they are filled to the proper pressure they should hold it so I don't see the point of this tool unless your constantly changing the tire pressure.
