Well, for a start you should get used to specifying, if it is an '05 IQ chaincase, or an '06 two stroke IQ chaincase, or an '06 four stroke IQ chaincase.
The '06 service manual has not yet been distributed.
The '05 Fusion and RMK (not the IQ Racer) have a 11.35" center distance chaincase. This is what the chart tells me for that chaincase.
24:41 = 1.71 ratio has 0.136 CD slack with a 94 chain
23:40 = 1.74 ratio It is too tight with a 92 chain, too loose with a 94.
24:42 = 1.75 ratio has 0.037 CD slack with a 94 chain
22:39 = 1.77 ratio has 0.136 CD slack with a 92 chain.
CD slack refers to the difference between the maximum chaincase Center Distance this sprocket/chain combination could fit, and the actual chaincase Center Distance of this snowmobile's chaincase. It assumes 0 deflection, which is not always possible.
The '04/'05 IQ racer had a 7.92" center distance chaincase. IF the '06 600 HO has the same chaincase...
24:41 = 1.71 ratio has slack with a 76 chain
23:40 = 1.74 ratio It is too tight with a 74 chain, too loose with a 76
24:42 = 1.75 ratio has slack with a 76 chain
22:39 = 1.77 ratio has slack with a 74 chain

Hmmm I wonder what chaincase are in the 600's then? If it was the same cc as the edge with 23/39 you would use a 74p chain. If it was the 900 chaincase that would call for a 92p chain. What's the cc distance on the 600 ho's? :dunno:

I didn't open it up yet. Thats from the spec page I reread today. I work Saturday, see The Stones sat night, and IRL Sunday, so I won't open it up till sometime next week.
Isn't the Pro-x case different? It does have the Phantom brake. No liquid cooled brake anymore.

They lowered the jackshaft 3" in the 06's, so it's pretty much a certainty that the 06 will have a different chaincase with a shorter centre-to-centre than the 05...unless they lowered the driveshaft 3" too! (the last part is a joke, before eveyone starts posting the reasons why they couldn't lower the driveshaft 3 inches!).
So, no point in looking at 05 numbers to plan 06 mods...personally I wouldn't be thinking about mods until I have tried out the 06 and determined what (if anything) might need to be done...the 06's better be pretty damn good right out of the box, and if it's not, better look into Arctic Cat or Ski-Doo or Yamaha gears, 'cause that's what we'll all be riding next year!!!
