Compared to the EB the production CF has the following changes:
1. Geared down (60/60 instead of 65/55)
2. Larger rear tunnel cooler
3. Straight rate 120lb front springs (instead of dual rate 60/120)
4. No flaps for the snow holes at the front of the running boards
5. Smoked higher windshield (instead of low black one)
6. Stator is a different part number...my guess is that it pumps out more juice than the 05 Firecat stator that is in the CF EB.
7. Rear seat has a hunk of foam to separate the storage compartment from the rest of the seat underside. One of the seat release tabs has a plastic stopper that you have to rotate out of the way to be able to move the release tab....kind of a locking mechanism to keep the seat on.
8. Gas tank has a spare spark plug holder molded into it above the secondary. It holds 4 plugs and has a rubber strap to hold the plugs secure.
9. Rear to front coupler blocks.
The West Yellowstone is the same as the EB except that the WY has the coupler blocks and is supposed to be geared down....However the clutching/gearing sticker on my WY CF7 says It's geared up (65/55). My dealer was supposed to confirm my gearing based on the serial number but I haven't heard yet....my guess is that the gearing change was a running changing during assembly and some WY CFs will have the 65/55 and some will have the 60/60....either that or my sticker is wrong! All I know is that Brown's Leisure World parts fiche says the WY CF has the lower 60/60 gearing.
There might be some other details but this is all the ones I know about.
Hope this helps.
Don't forget different ECU, a larger gas tank, different side panels, drive clutch (weights), driven clutch (helix), and who knows what else that we haven't discovered yet...
