Drive spring (part# 0646-229yellow/white), Helix (part# 0648-126 53/51deg.), and Secondary spring (part# 0648-114red/white) all stay the same for 5000-9000 ft. & 9000+ ft.
The only thing that changes is the weights from stock part# 0746-653 (63.5 grams) to part# 0746-617 (60.0 grams) for 5000ft. - 9000ft. or part# 0746-655 (56.5 grams) for 9000+ ft.
The gearing recomendations are printed under the hood on the fuel tank or you can click link below. Hope this info helps.
ps When are you leaving, where are you going (Bighorns I assume given the mention of Sheridan, Wy) and for how long? Planning something for 3 weeks from now so if you could if you could let me know how the conditions were I would really appreciate it.... Click Here for Firecat altitude gearing
I was there 26-31 of dec. Snow was thin. Had to look hard for good riding, but was worth the drive. Trails were excellent, but who wants to ride the trails there?
Unless it snows more, it really isnt worth the trip, but you cant ride here.
You will be really pleased with the F7 on the hills. Sidehills very well (make sure you pull the swaybar), very manuervable (sp) on the hill, rides light, good in the powder. I was very happy.
I learned how to replace both a-arms and front shock on my F7.
I will be heading back out Feb 6.
We were all riding very cautiously.
5 in out group:
F7-right side a-arms & shock
ZR6-right side a-arms & shock
XC6 trailing arm
