I put a dual Dial a Jet On My DS it now goes from 4000 -12,000 ft without as much as a hickup. wow. a buddy put a set on his raptor he can adjust his jetting in 2 mins. Alot of my riding buddies are installing them.

 

yeah i like mine...i installed one on my warrior as a test before i tried to tackle the dual carbs of the Raptor. Quad throttle also becomes very responsive. nice product. Buddy of mine races sport bikes and they've been using them for awhile with nothing but good results. i've had mine for a year with no problems.

 

would it allow enough flow for something like a 686 rappy on race gas?[img]i/expressions/face-icon-small-happy.gif[/img]

 

air you said from 4000-12000. what about 0-4000.
