Default 470 mxz clutching tips

I installed a 470 motor in my 7500 blizzard and I would like to wake up the stock tra clutch. Any suggestions? The original 354 liquid motor is in good shape but was lazy in the sled. Sometimes I had to push it to get going. Didn't seem to have it's full potenetial. Any clutch set-up info on this motor would be appreciated. Thanks.

I'm not a skidoo person and don't know anything about their clutches. But I know a 7500 Blizzard is an older snowmobile, simply refreshing the components should yield a significant increase in power. I've heard of people replacing clutch springs every other season, there may be 15 years or more on your clutch components. I'd take the clutch apart and wash it with warm soapy water and refresh everything inside it, that would be a great start.

X2 on that!
Also since you are having to push it to get it moving, I would look at the plugs, you may have a fouled one.
