Upgrading my 2006 summit 600

I have had my snowmobile for a year now and i would like to get more power out of it. I am thinking about putting a clutch kit on it but wanted to hear what you guys thought. What are the best upgrades you have done to your sled. Be specific to what things becuase its hard finding parts for the 2006 600 HO sdi. Thanks for the input.

OK you've got a few different thing happening here. To get better performance there is a couple ways to go.
#1 lose some weight - people say foam under the hood, aftermarket can (see #3),unless you do significant engine work keep the stock pipe but you can lose the clamshell and ceramic coat the pipe.
#2 Get the power from the motor to the snow - First lose the black cover off of the clutch to cool off the belt and whenever you change your belt stay with OEM (alot of aftermarket belts don't hookup very well), SLP hot air elimination kit (same reason), clutch kit mod - there's alot of options here I think less is more unless your doing big motor mods and always talk to the pro's (dynamo joe or big john).
#3 Put more power in the motor - I'll keep this one simple. Talk to a pro, tell him where the ride and how you ride and how much you want to tweek with the sled after you get the work done then you can have an intelligent conversation about what is right for you. I think less is more but that's what is right for me. and oh yeah the can and pipe are a tuned part of the motor so before you just buy something for sound or cost talk to the engine builder. I prefere the phone becuase 10 minutes is worth hours of this back and forth typing stuff. Here's your engine link.
