At Accelerated Technologies we specialize in helping riders optimize their snowmobile to their
expectations. Whether you like to ride quickly on flat-groomed trails, jump driveways, or cruise
along in maximum comfort and control, we have the product and the expertise to deliver!
Sag and Set Up
Before we begin setting up a snowmobile chassis, we discuss with you your riding style and what is important to you. Do you like to jump driveways and lift the skis for miles down the lake, or are you more about groomed trail, flat cornering performance? Perhaps your go-fast years are just behind you and you want ultimate comfort and light bar effort while casual trail riding? We will set up your sled to get the best out of it, for you. During a set up consultation, we set ski preload to the engine weight and your riding preference, then set the rear torsion spring preload to support your weight and give you the rear sag we need, then finally match the limiter strap and center shock spring preload to balance the vehicle. If you are lucky enough to have damping adjustment, we can coach you on that too! This is the base service we do every year for Craig Nicholson, The Intrepid Snowmobiler, to help him get the best out of his new Ski Doo Snowmobiles before every riding season. For Craig Nicholson, we also install Elka Snowmobile shocks up front to help us give him the absolute best ride possible in terms of comfort and performance. Elka shocks have a unique dual rate spring system that allows softer than stock spring rate over the small bumps in the top of the shocks travel, then stronger than stock (at our discretion) spring rate as the shocks near their suspension travel bottom, to help reduce harsh bottoming on the big hits, giving a much larger set up window where they work great at all different speeds. As we continue through the set up, we often find the stock torsion springs are woefully inadequate for the average sized snowmobiler and may recommend an increase in spring rate. Larger riders typically need to run their torsion spring preload eccentric blocks at maximum to achieve target sag and are in trouble if they want to carry gear, or even just experiment with going stiffer. We have put stronger torsion springs on Ski-Doo riders that are as light as 150#s! With stronger torsion springs, the rear of the sled will stay up, nice and high, giving you maximum travel over the bumps, as well as maintaining good ski pressure. If the torsion springs are too soft, the skid will bottom often (uncomfortable ride) and ride low, giving imprecise steering and allowing the sled to run wide on corner exits. The sled will be more stable and predictable if the proper torsion springs are used to hold it at proper geometry. Call us for a recommendation on springs and then book an appointment for your set up!
Snowmobile sag and set up starts at $110 but can often stretch to 2 hours ($220) as we make changes inside the skid frame, or maybe even a little longer if your shocks have damping adjusters. Often more time is spent on training the rider on all facets of snowmobile dynamics and handling than actually doing the set up. If you are interested in taking the next step forward to understanding how your sled is working underneath you, and what all those adjusters do, book an appointment at our shop.
The vast majority of OEM aluminum body snowmobile shocks are not very hard anodized on the inside diameter of the body. Then, when they start operating during the first few tanks of gas, the shock pistons start to wear off high spots and break into their bores, exactly like your engine did when it was new. However, in an engine, all of the break in contamination can get out. In a four-stroke engine your engine oil suspends the break in particulate and it gets cleaned out in the first couple oil changes. A two-stroke engine washes the break in bits out by doubling or tripling the oil injector pump setting, flushing it into the tail pipe. But… in our suspension, our poor little shocks with their tiny amount of oil just end up swimming in the metal bits for years until they either tragically fail, or the damping gets so weak that the rider finally realizes they need to service their shocks by the complete lack of ride control. We have serviced and revalved many KYB shocks with as little as 500km on them from brand-new and the oil was black, stinky, and disgusting. The abrasive break-in contamination just can’t get out and collects down around the shaft and seal head making the shock sticky. Sediment also collects in the shim stack holding it open and dramatically weakening the high-speed system. Often, we find the steel shims beginning to rust in the first year from water in the oil. Also, don’t think for a second that the purchasing department at the OEM shock suppliers are picking the highest cost, highest quality synthetic shock oil for your machine. No way, not when they are building tens of thousands of shocks a year and are under strict pricing directives from the OEMs. Get your shocks serviced and cleaned after the first few rides or after the first season and have the oil changed out with a good, high quality synthetic shock oil. If you do this before the bores and bushings get too scored up, the shocks will last and perform much better over the life of your machine.
Expect a dramatic improvement in comfort, bump compliance, and performance with a shock service, which gives us the chance to remove all the break in contamination, clean the shim stack and rebuild it with fresh nitrogen, synthetic oil and grease.
Base price for a Snowmobile shock service starts at $90 for rebuild-able straight body shocks and goes up to $125 for full remote or piggyback reservoir shocks with clickers. As with any snowmobile shock service, this does not include any required seals, o-rings, nitrogen seals, lathe polishing and other repairs that may be needed after inspection. Revalve snowmobile shock service and Re-springing is available if specific improvements are desired.
Inside snowmobile shocks, we often find the shock suppliers will engineer a valve stack that is very tame with a very light stack. The stack is often so light that closing the compression adjuster (if you have one) just diverts more oil towards the shim stack and it opens sooner, giving almost no noticeable change to the rider. We believe this is a safety precaution, done by the manufacturers, ensuring the shock doesn’t get dangerously stiff if the rider completely closes the adjuster. Darwin protection as it were. A Snowmobile shock revalve can actually make your shocks change and get firmer and softer when you adjust them! Imagine that. Another common issue we often see, is tragically slow rebound in the rear skid shock (not mentioning any names 137” Vipers and Cats). Slow rebound is ok if the vehicle is being operated at a walking pace, but as soon as the operator picks up the throttle, even a little bit, the lethargic rebound doesn’t let the sled recover back up to standard sag height before hitting the next bump. The result is a low vehicle ride height and a confused sensation in the rear skid, often misinterpreted as very stiff compression due to the shocks living down in the bottom of their travel as they encounter bumps. Here is a quick test… sit on your sled and have an observer note how far your snow flap is from the trail. Then ride away at a moderate pace and have the same observer watch your snow flap again. If it is consistently lower than observed when stationary, your rebound is too slow. Open it a few clicks, if you don’t have clickers you need our Snowmobile Revalve Service. Another test you can do before the snow flies is to just push down gently on your bumper as deep as you can then release. It should come back and stop in about 1-1.5 seconds, if it takes any longer (especially in a warm garage) your rebound is too slow. Depending on the quality of the original shock package, we may be able to service and revalve the shocks to get the very best out of your stock shocks.
The revalve fee for a Snowmobile shock starts at just $65 plus shims and will be added to your shock service if you need it. Shims range from $2.50 to $3.00 each. We may need two or three in a shock that is close, or 10-12 or more if the shock is way off. We can guide you completely on your revalve needs and let you know if you would benefit.
Here is a bit of bad news, the OEMs need to keep the cost of your sled reasonable. In doing so, your skid frame is not full of high-quality needle bearings. Sorry folks, it is metal sliding on metal, or even less durable, metal sliding on plastic. Surely, they will have grease fittings for these important metal on metal pivots, right? A current R-Motion equipped Ski Doo has 2 grease fittings on the rear skid frame, yet there are 18 pivot points that could use a bit of lubrication every ride. Why? Well, what gets generated when metal slides on metal? Heat. This byproduct of heat melts snow and ice turning them into water. Warm parts expand, cold parts contract. Cooling bushings that are soaked in water and snow draw that water in to the joints as efficiently as a plumber can draw solder uphill into a copper pipe joint. How do we know that water gets in there? What comes out for the first few pumps when you pump your grease gun on the few grease fittings you do have? Water, every time! Water causes corrosion when left over time. Corrosion sticks parts. Sticky skids don’t absorb bumps, they send every impact right to the seat. When we have your sled in the shop to do a SAG and Set Up, or we are removing the shocks if we are doing a Shock Service, it is a great time to service and grease your skid for you. We use an ultra -high tack waterproof grease that resists wash out in the un-serviceable locations, and a lower viscosity grease on all the pivots with grease fittings. If you aren’t up for it, give us a call and book an appointment. Making sure all these critical pivots are smooth and lubricated is what makes a brand-new sled feel… well, like brand new.
If you want the ultimate next level in skid suspension performance, we can install the Mainway Greaseable pivot kits. These ultra high-quality kits replace the bolt and bushing with a higher grade and quality bolt complete with a grease fitting!!! With the Mainway greaseable bushing kit in place you can quickly eliminate all friction in your skid before every ride with a few pumps of your grease gun. Most sleds go from 2 grease fittings to 22 after the full kit is installed! If your sled is a ‘keeper’, this kit is a no brainer. While in your skid, we check wheel bearings and sliders and replace if necessary after checking with you about these items.
We can replace your standard sliders with Dupont Vespel glides that last about 3-4 times as long as the standard ones while rewarding you with reduced friction which equates to higher available speed and better fuel economy, plus the added protection when on a cold, dry trail or other temporary situation where slider lubrication is lacking. Reduce the stress on a hard-packed railway bed, where there are no corners to help generate snow dust… go Dupont Vespel! They are 4 times the cost of standard slides, but if they save you doing the job 3 or 4 times it’s worth it! Face it, you likely won’t be changing them out ever again during the time you own your sled.
Need a new Track? We are a Camso dealer with their awesome range of standard and pre-studded tracks. If the skid is out for service, most of the labour is already paid. Drive shaft removal is all that is lacking to dramatically upgrade the shoe that contacts the ground!
Want another huge handling improvement? C&A Pro make 7 different skis for every possible rider and sled combination.
Our labour rates are $110 an hour.
Up Front Service
Many riders bring their sled to us every year for drive belt inspection or replace, clutch service, chaincase cleaning and adjusting, spark plugs, power valve cleaning, carbide inspection, replacement or sharpening, brake pad inspection or replacement, and brake caliper service. We also can align the handlebars to the machine center and then true the alignment of the skis, setting the toe out. Nothing is quite so annoying than living with bars that are gently pointed to one side after that rock you hit last year.
We are central Ontario’s Authorized Hurricane Performance dealer capable of turbo installation, ECU reflash of the Yamaha Sidewinder and Arctic Cat Thundercat. Re-clutching in house and re-gearing are often mated to a big horsepower increase. Elka Snowmobile Shocks are for sure one of our biggest sellers at Accelerated Technologies. We are Canada’s largest Elka Snowmobile shock dealer and have become experts in their selection, installation and tuning. An extensive range of suppliers ship parts to us constantly to help us maintain and improve dozens and dozens of sleds a season. We can custom select a Camso or Kimpex track to best match your expectations and a wide range of skis from suppliers such as KIMPEX Skis, C&A Pro Skis, xx skis to match your track and turn your sled like you dream it would.
Labour rate is $110 an hour for most Performance Projects.
