Can I use the jetting that comes with the dual exhaust 142,145 at 500' above sea level if I drill holes in the air box lid and remove the snorkle thanks.

 

i think if you do the air box mod's also it will be a little lean at your elevation, i would put a 145 in the front carb and a 148 in the rear if you are going to mod the airbox........

 

I think Stakk is right .... I am at 1000' here in Akron .....

I am using the HMF recommendations..... plus a dial-a-jet system
( worth about two more jet sizes )
And two holes in the air box...... and I removed the snorkle

 

Hey Vforcer...... I am going to add the HMF duals as well, along with a dial-a-jet syatem, and thinking about the Airbox Windows from dial-a-jet also. Did you use the dually dial a jets, or the standards?

Is the quad much faster in its modified form?

 

Based on the information I have found the dual dial-a-jet sounds like the ticket to get it dialed in.

 

There is one dial-a-jet induction jet in the rubber boot on top of each carb......

It that the "dual dial-a-jet" system ????


I used the sliding air valves from the dial-a-jet people also ....

Summary ... my bike has two air holes, 142/145 jets, and the dial-a-jet system , with the dual HMF exhaust

 

There are 2 nozzles for each carb, so 2 rubber boots.
