2009 BRP altitude specifications

 

[Throttle Junkie]

Only one major issue.....

Cam angle (degrees) 43°-47°....for all

 

[caper11]

Only one major issue.....

Cam angle (degrees) 43°-47°....for all

And how is this a major issue? I like the fact that my rpms dont change much from powder to tracked and it revs the same at 5000 to 8000ft, very responsive back shift and the sled pulls hard with 45 MPH track speed in powder, well mine does anyway. all mine needs is to remove the stock setscrewsto get into a lower clicker.

Reverse cut helix is a bad decision in my mind. Any track speed under 50 is pretty weak for a 425lb 150HP 800. Some may like the reverse cut helix, but in my mind it's one of the dumbest things ski-doo has done. Only sled that make sense to me to maybe have a reverse cut helix is a turbo....slow shift on bottom till it build power....I just can't see it. I am going the other way with mine will probally run somwhere around a 46/40ish.....48/42
