I have installed the heel clicker kit for a tra (trade ramps and levers for ramp-levers) on a couple of mxz 800's. You pretty much ruin the drive clutch. It is a pain to cut out the clearence holes in the side and impossible to get it perfect. It took WAY longer to install than what they said and the setup they gave wasn't even close.
But, once we tuned it in it worked good. The biggest gains are low-end to mid-range.
You can achieve the same performance from a properly tuned tra, although most will say the tra is less consistent and more finicky. So a good alternative is to buy a comet clutch and buy the heel clicker kit for it. You don't wreck the tra that way. You could also get a Polaris clutch and have it tapered to match your crank.
machz69, I think, that since you decided to keep your sled for the winter, you should leave the clutching the way it was last year, as it was plenty quick and fast. Also, if you decide to put a 1 1/4" track this winter, you'll be very hard to catch in 1000'.
Just my opinion!
machz69, I already sold my 1.25" (9818) to my buddy with the XC 800. I now have the 136" version, the 9819 (1.25") and a rail extension kit from Royal Distributing. I should be able to start on my sled at the end of next month, as I still have lots to do before then. If you don't have a 1.25" track yet, you could call up Gilles at Georges Garage and see what he has. Very good prices I hear !
Hope this helps !
