Need help '03 Mountain Cat 900 setup

[delbertdiggity]

Going out west in a week need to know a good setup for 8,000 to 10,000 feet.

'03 Mountain Cat 900 162" Holtz rear Suspension
The "thing" can
boysen reeds
k&n air filters on carbs

Need to know:
clutch weights
jetting
rpm?

Was told at my local dealer the 900s should run at about 7,300 to 7,400 rpm
with 64 gram weights, green yellow spring in primary, and a different helix.

Figured there would be some guys on here that have had alot of time get get this "old school powerhouse" dialed in good. One more thing should i leave the track (attack 20) on with paddles pointed forward (looks like it should be flipped around) heard guys sayin leave it in cold weather powder flip it for spring heavy snow.

Some info would be much appreciated Thanks!!

Yellow green primary with 64's should get you in the 7800 range.

This is good.

put in a 49 degree helix, yellow secondary spring or a red in the loosest hole.

Run 350 mains, needle one step leaner than center. Don't run down the road at 6500-7500 rpm throttle for a long time it will get hot. But it will run well.

As for the track. The snow is pretty deep right now so if the track was in the Powder position it should work pretty well.

Pin it!

try changing gears to 20-43 new chain stock primary spring red secoundary spring change springs if more than one season old they are not expensive and tension wares out from heat you can run 330 jets have to change needles though run on mid setting but don't hold sled at constant rpm on trail or mid range use choke to cool cylinders on trail but when you get to the hill hold her wide open on the climbe and enjoy when you turn out flash choke acouple of times going down and by the time you get to the bottom you will beready for another pull had 03 900 m/c 151 1750miles same set up no problems
p.s burn premium also it is a proven dyno set up to run no more than 7300-7400 rpm with stock pipe after that you just loose hp.
