Hey guys. Looking to do some upgrades to the sled before winter gets going. Been riding sleds for a couple years now and looking for a little more zip. I have an 02 viper that is bone stock. I do mostly ungroomed trail riding and ditch banging, but do get up to the UP each year for a weeks ride. Looking for some help figuring out what upgrades to do.
Clutching - I notice most people recommending Heel Clicker systems, and when I looked I see they have 3 different options. What is the different between them? Drag & Fly Primary Kit
Heel Clicker 2 Speed Primary Kit
Heelclicker Primary Kit
Track - I will need a new track next year, so what should I look at to get the best bang for my buck? Paddle size, Manufacturer, tread patterns?
Suspension - I found a write-up on suspension improvements I am going to look into
Any other ideas of upgrades? I don't need a drag sled, just looking to make it a little quicker. I would also like to make it sound better, but I am seeing a lot of negatives about doing exhaust changes? Is there a difference between doing a can or doing pipes? If I do just a can will it hurt performance?
Thanks

Gearing, clutching, pipes, jetting, traction. Cans sound nice but pipes are the better HP gain. Also fuel suckers. Also Maintenance. Major power robber.

buy 40-10 hc the original bolt in kit, stay away from 2 speeds and dragon flys. Buy a dalton 48/34 or 48/36 helix. This will perform very well and really wake up the sled!
when you get the parts in hand post and I will give you the complete set up to put into the weights.

x2 on mrviper's clutching reccomendations. that is basically what my brother ran in his 02 viper as reccomended by turk. worked great off trail and made it a great corner to corner sled at home.
cammoplast ripsaw/ice ripper is a good up-grade for the 02 vipers as is extending to 136" with a shock re-valve. you will have to trim either for clearing the heat exchanger protectors. if going bigger that 1-1/4" lug, i reccomend 8 tooth drivers. extroverts would not be a bad idea either as it will help with slide wear.
do not reccomend the can unless you want to ceramic coat it as it looses heat way too fast on long pulls. in areas, the mnr/dot/popo are starting to crack down on aftermarket cans and pipes so i reccomend you do your research for your primary riding area 1st. stock=more reliable/consistant sled.

Last year I long tracked my viper to 144. Besides long tracking a viper for a better ride I would look into a boss seat. Its a bit of money for the seat but probably one of the best mods I've done to my viper. Feels like a completely different sled.

For off trail use/ditch banging, I'd recommend the cobra campo last track. Out performs the ripsaw/ice ripper in almost ALL conditions with the exception of hard pack/icy trails. It grips powder better, and softer snow such as early spring trails when they start getting soft/slushy. Hold off on the pipes. Try the 40-10 heel clicker primary kit first. It's a performer.

Thanks guys!!! Appriciate all the advice and such quick responses. Has anyone ever just dropped a gear size to get a little more torque out of their sled? I know this will hurt top end, but seems like a really cheap way to go if I can't do the clutching yet.
Anyone have suggestions on where to buy parts, especially since Shadetree is down.

My piped viper had a big difference in power when I dropped a tooth on the top gear. Pulled even more with 2 tooths dropped. Just having a stock motor I would only drop 1 tooth. By the way by doing different gearing on you're sled you will have to mess with the clutching though. When I did my gears for the viper I used port Yamaha. They had the lowest prices at the time a few years back on gears.
start with the heel clickers. almost the same as gearing it if staying short track. will still loose some on top end but accel will be much improved. try port yamaha for your parts. other site vendors are good too.

I like my viper geared down one. I have seen as high as 118 mph on the dreamometer and the conditions to see that, or anything higher are so rare that it is well worth the trade off for me. Mine is trail ported with heel clickers.

I have a set of SLP Triple pipes for the viper that I am looking to sell. I bought 2 sleds last year, one had a blown motor the other had a trashed skid. After monstering the 2 together I have an extra set of pipes. Running the Bender triples on the girl.

Born, did you have to do any clutch adjustments? Did you just drop one tooth or did you drop one and raise one?

I dropped to a 21 on top and left the bottom stock. I had already dropped my gearing before I put the heel clickers in. Had dn20s in before that. The gearing drop will most likely raise your shift rpm 100 to 200 rpm at most. If you go heel clickers you will be dialing them in anyway. The setups on here are a great starting point but you will will need to adjust them some for your sled to get to the best rpm for your sled anyway. 8500 to 8600 on a stock Viper. No 2 sleds react exactly the same. Rider weight, traction, conditions, temperature, & sled power can all make rpm vary significantly. I started with Mr vipers setup which is great but needed to be adjusted for my sled. Conditions will always make shift rpm very some. For trail riding the best thing to do is set it up for the middle unless you have a serious race or just like tinkering. This goes for all weights. It is really not that hard to make needed adjustments and get a feel for it. I sure that many people on here would be happy to help you through it.
