2011 Apex is here!

What RPM did you clutch it to. Spec in the manual is 10.000-10.750. Engagement 3.200-3.600. Mine is 3.200.

10,400-10,500 seems to be the sweet spot with a stock intake and exhaust.

Compared to the old engine, how much more helix / weight does it pull...?
Not trying to figure out the spec of your clutch kit, just asking to get a reference compared to the old engine.

It has more low/mid grunt to harness than the old engine. Comparing the clutching to an old Apex isn't a 100% equal comparison because you are comparing a 121 (old short track) to a 128 (new short track) and a 136 (old long track) to a 144 (new long track).
 
Come check out the 2011 Apex XTX that we'll have on display at Hay Days!

Are you able to share the stock pre 11' apex track hp curve to the 11' stock apex power curv and post it up?
 
This is of a 2007 Attak vs a 2011 Apex XTX (136 vs 144). The 2011 has quite a bit more all the way through.

Red = 2011 Apex XTX

Blue = 2007 Attak
