Jetting from sea leavel to Sd at 6300 ft?

[kinger]

Hey guys,

I always ride below 3000' but we booked a trip to South Dakota (lead area) this winter and I guess they are at 6300 ft, what jetting should I run? ANy clutching changes? Keep in mind I have nitrous clutched at 9500 off the bottle and 10500 on the bottle with polaris weights.

Thanks

You could rejet, but we normally don't. It won't be at optimum performance, but for trail riding will run fine and get good gas mileage yet as well. For the clutching you will either have to drop back on helix or remove weight from the weights.

How far to drop back on the helix 10 degrees do it? If nothing is done it will under rev correct? Thanks!

Kinger, I run filters with 170 main jet and a 20 pilot jet. For clutching I have a G/W/G primary spring with 53.2 HH weights, white secondary spring at 60 with a 52/38 helix. You will enjoy riding in the Black Hills.
