By way of installing that skidoo maintenance pulley kit - as you remove the wear parts you will be doing an assessment of the clutches and as you install the new parts you will be getting the clutch itself to generate excellent performance.

Maintenance.
Since 2008 there have been 3 updates on clutch wear parts for the tra-7 primary.
The maintenance kit below gives the latest/greatest wear parts. Once installed they take about a ½ tank of petrol of driving to “break in” and start to perform with consistency.
Maintenance kit for drive pulley
(buy from local skidoo dealer)
1 spring cover assy, 3 rollers, 1 bushing, 6 slider shoes and o-rings, 1 circlip, 3 cotter pins & lever axles 2008~10, 800PT & Etec
BRP#415129627
@ $139.00(CDN) ($129 USD)
I only recommend the original BRP primary clutch rollers because they are 1) the original diameter and 2) they weigh 9 grams. The fact of the original smallest diameter is a benefit with a great degree towards the promotion of quick backshift and strong bottom end acceleration using the most of the meat of the engine's torque curve.

Any one of the major parts and/ or a combination of them all wearing or worn out will contribute to engine speed lowering.
