?s about different valves

I have never had problems with GC450. I did have some issues with the GC250, but I called up GC, they sent me new diaphrams, and never had a problem since. Great company as far as that goes. You can get them from gravity werx also.

I have had herions for 5 years now...same set rolled em in winter, rain...every day...never had a problem....I have run parkers as well and GC250's the parkers are killer too, but were slower than my herions, and the 250's make great paperweights, at least in my opinion.

hmm...i see. i just wanna get up fast and down as well. my gc 450s never had problems and i think im gonna go with that.

there you go!!!! ok its with cylinders, but you can do a rollin 3-wheel and thats about it, unless you chain up one side of your rearend around the frame you can dog leg the back thats really fun!!!!!!!!!

oh yea stick w/ what works on the valve subject
