1) Check your belt to primary sheave side clearance, should be .010" to .015" w/NEW belt, mine was .070" from the factory.

2) Install a new primary clutch spring @ the start of every season. (approx $31.00)

3) ALMOND/red stripe SPRING (POLARIS part # 7041988)
a) 66 gram stock weights, OR
b) SLP's 68 gram MTX'S with 3 grams in the tip, plus 2 to 3 grams in the middle, slight improvement over 66's

4) Send your primary clutch out to have it balanced. Since these sleds have a bad rep for wasting the crankshafts, put a dial indicator on the crank snout (remove primary) and periodically check the run-out. 002"-.0025" is the MOST I would want to see. Made a NOTICEABLE improvement in smoothness and extends crankshaft and clutch life, they drilled 8-9 lightening holes in mine, that's how far off it was from the factory!! SLP and others charge only $35.00 for this service. Do this after you've set the belt to sheave clearance.[/b]
Great stuff Kraven. One Question tho. I am getting a new Primary this winter from a dealer. A brand new one. Do they come balanced? Or should I just get a rebuilt clutch and have someone balance it for me? I just had a new crank put in 500 miles ago.
