2018 Ski-Doo Linq System Removable Snow Flap Instal

No credibility

This guy is a joke calling himself a backcountry expert. If you said removable snowflap expert you'd have some credibility.

I'm not seeing any credibility from your post. By the way, you were running the 850 Demo way too high in RPM. Maybe you should learn how to adjust your own sled before attacking Dave or anyone for that matter.

I'm glad you could see the gauge because I sure couldn't.

Max Engine RPM is too high

I can hear the RPM from the East Coast.

That is what I don't understand. Why don't you setup your sled(s) so they stop blowing belts or wearing them up so fast? You can't tell me it is difficult.

The 850 is a mountain sled developed and tested less than 15 miles from my house. What kind of set up do I need to do?

How BRP comes out with these sleds doesn't concern me, and never has. So I am the wrong person to rant about Box Stock setups. I have always had to setup my sleds for the application. When they are close for what I need, even better, but I never count on it, never.

For extreme riding like you doo, the very first thing to do is lower the RPM to where it doesn't go higher than 8000 rpm MAX! That means you need to load them up. At least this is what I do it out East. There are professional tuners out West that say the 850 needs to run between 7700-8000 rpm max, and usually between 7800-7900 rpm, so it seems to be the same from East to West.

The second thing you need to do is look into the alignment and gearing. This is a big subject, but there are ways to make it simple. Factory settings are usually very close or not far off. So the easy way is to make small adjustments in the X. The Belt Print will show you were to go next.

Need the following for a better setup easier on belts.

1. Elevation?
2. Track Speed during climbs?
3. Track Speed cruising to reach those areas?
4. Max Track speed to reach those areas?
5. Track Lug Height?


By the way those are fantastic videos of your climbs.

Why does it matter who it is? If you are so interested in who is who and what they are doing, there is Facebook for that craziness.

Yeah fair enough guess it doesnt. Point is the guy (jhurkot) knows a thing or two about setting up a mountain sled and I'll leave it at that.

Anywho, Im just here to learn so keep on keeping on.

Here are two videos. The first from jhurkot on a Demo 850, and the second from an professional tuner. Just by the sound we can tell the one in the first video is running slightly over 8100 rpm.

In the second video we can hear it run between 7800-8000 rpm. Between 0:25 and 0:40 min the rpm is roughly 8000 rpm. Between the 0:40 and 1:15 min it quickly drops to around 7800 rpm from the steeper climb and goes back up to 8000 as the terrain levels off some. To get it down that far you need a lot of pin weight. I believe the sled in the video is using stock components with 19.2g for 3000-7500 ft elevation (16.7g as delivered + 2.5g). I am not sure of the elevation, so that's why I am having to guess on the pin weight.

Pretty hard to clutch for bang on 7900 rpm in mountain riding. The elevation and amount of load applied based on snow depth and inclines varies every few feet. $18k sled can't run from 78-8100 rpm and not chuck belts... someone screwed up badly. But why is it only certain sleds??
Many many xm' s are running around out there without spot on clutching. Either low or high rpm and being bagged and getting great belt life.

Daag you are correct in that video I am over reving a little bit. The story behind that was my buddy hurt his knee and we were going back to the truck and wanted me to try his sled out. Sled was 100% box stock besides a loud can. Definitely over reving. Still climbed pretty good in waist deep snow but some performance definitely left on the table. I have a set up that seems to work pretty well now that involves aftermarket clutch weights. I personally like to see 8000rpm on the calculator screen gauge Here is a video with stock weights with washers added (not the fix but the ZRP adjustable weights took forever in the mail). This was a different sled, stock can. Sled now has the adjustable weights in it and running quite a bit better. Both sleds are 850 165" 3" at an elevation of roughly 5000-6000ft.

Re: Max Engine RPM is too high

Why is everyone on here trying to chase away a sport ambassador.. He does a LOT for the sport.... did the guy say ANYTHING about how the 850 runs or mention anything about ANY of what you guys are bashing him for? Hes great at what he does... He takes a new product and gets out to test it and instead of looking at things in a book... hes shares them on here. There are alot of people that LIKE that kind of stuff so dont wreck it for them. I like getting to see all of the new stuff in action. Theres plenty of other threads for many different topics... Keep chasing good people out of here and its going to end up being 6 guys sitting here arguing about brands. Keep em comin Dave.

Agree to disagree. Guys like Dave annoy the piss out of me. Its their job to convince you to spend your hard earned money. Doesnt matter if its on a pile of crap....doesnt matter to them. They still get their paycheck, or free stuff. I come on social media to get opinions from guys like jhurkot, lilduke, and Rene St Onge. They know their equipment, can ride, and most importantly.....arent afraid to give an honest opinion about something if it isnt working.

 

[jhurkot]

Norona said lots about how the 850 ran and was tested for 3 years during snowcheck time last spring... then comes on here all ****ing winter saying the majority of people don't have problems is bull****. A post on this forum by him is no different than a paid skidoo advertisement on the sidebar.

The washer brought it down to about 7950-8100. It will need a lot more weight to bring it down to 7800-7900. What ramp are you running? And elevation? Very fist thing to doo is swap with the 417127039 Black sec spring to lower the slip in the secondary.

Another thing that I recommend is doing shorter runs on the same climb to measure the belt temps and look at the belt print, then go back down the hill to your tools and add more pin weight.

I would go on because clutching is my favorite subject of all, but I realize this is a Snow Flap install thread. I doo find it a shame that I haven't found a good clutching thread on this forum.

Please start one - you have the knowledge to do so! Also adding links to clutching sites would be nice, do your best to ignore those that would sidetrack you.
