The only thing i have ever done is cleaned carbs,power valves and put new track on it. is it possible to get a little more out of the hole on this sled. any input accepted thanks all

Do a search, lots of info on clutching.
HC's will help the holeshot. Torque limiter will also help keep the clutches lined up. Put a rear heat exchanger on if you don't have one already.

I don't think you need the rear exchanger unless you pipe the sled. In stock form it runs fine. I have one on mine only because I ran pipes on it at one time. My father has an identicle Viper as mine (2002) without the rear exchanger and his runs great. What I have noticed over the years is mine actually has more issues with snow hanging in the tunnel while his does not. As for clutching I have had good luck with the Heavy Hitters. We run them on both our Vipers. I have over 7000 miles on my set with zero issues. My old man has around 3400 on his. As for the Heel clickers, I know there are quite a few people that have run them......just not me. From what I have heard there is more tinkering involved with the clickers, you have to run that tall spring which is a bear to get the cover on the clutch and some people have mentioned there clutches run hotter. With the Heavy Hitters, once you get them set the tinkering is over.

I know either changing your 9 tooth drive sprocket to an 8 tooth , or drop the top gear by 1 tooth in the chaincase will help a bit more in bottom end .. if you want harder engagement in the motor you will have to do some research on clutch kits . I called Hauck powersports about clutching kit they have a trail kit which consists of 1 primary clutch spring, keep the stock weights , and also a different helix and secondary spring which they swear will have an improvement on takeoff

I have bought sleds from Pat and bought clutch kits from him. Personally I don't think the bang for the buck is there. He will charge you probably over $300 for a clutch kit that is just a spring or springs with a helix and if your lucky some weight rivets. Not much adjustability there IMO. With the Heavy Hitters you can dial it in for YOU and YOUR sled only. Remember no two sleds run alike and no two people weigh the same or ride the same. Heavy Hitters are less than 3 bills too. I don't own stock in them......I just know they work because I have run them since my sled was almost new as mentioned. I won't go on and on on my conquests with my Viper, but lets just say I have ran with or beat alot bigger sleds over the years. That's why I like them so much.

Thanks all for all the input and suggestions 
If you do alot of marginal snow riding ie; road running or lake crossing or mild weather you will need a rear exchanger.

I have thought about putting a rear exchanger in my 02 Viper, but I have never had a problem over heating. I do, do alot of lake running but have not had any issues. Some people say they do, but on my sled I have never had any issues.

The first year the Viper came out I do remember alot of owners mentioneng they had issues with over heating. Of the people I have been around that own Vipers, I have yet to see it.........but they did sell alot of 2002 models. It was the best selling sled of the year that season.
