Rear of sled severe sag...... Pls help

Here’s the deal. If in lower position (Yamaha)to have low ride height you need srx springs. To have the exact same height within 1/4 in it needs to be in the upper hole with std springs.(Cat) maybe bogeys are a issue I do not know that. Front is same for both.

Great research Canondale every thing is starting to come together. I don't think the boggies will be an issue.

Only thing I am not sure of is the rails and if they have the same geometry. I sure hope they didnt mess with that Yamaha/Cat. Its simple enough to try for guys. Two bolts
 
This Tech Exchange was posted last year. Cannondale, I think you may have shared it on here.

Yamaha came out with this notifying what the proper rear suspension mounting position should be based on the Non-ARCS and ARCS front-end. Would love to hear from Jaret what Yamaha found in their testing and why different from Arctic Cat's mounting position.

It was me. Perhaps Yamaha wants to slow people down to lessen warranty claims? Put it this way if my sled were as high in back as what I saw I would be removing bogeys or whatever it takes to get it lower. Crazy
 
I have found running my front suspension with the arms almost level, Very slight incline, it handles on rails and steers nice. It is slightly lower than most but the new spindles would allow the same angle with an extra inch of belly clearance, it would raise my COG by one inch but maybe it would ok? Not sure but with my arms almost straight it’s on rails. Worth trying M2C

So this all is making sense to me now that I reflect back on my last two seasons. I have a '19 that I then converted over to the new ARCS front-end along with the new rail, etc. because I wanted to have the latest and greatest and needed something to do during the summer months. Well, now that I think about it, I had to run my ice scratchers a lot last winter due to over heating. The winter before that with the '19 setup, I rarely had to use my ice scratchers and never overheated. I'm sure the over heating had a lot to do with how high it sits in the rear. I may have to play with moving back up to the upper hole to see how it handles with the front-end changes.
 
MOTOTOWN you have no idea what kind of testing Yamaha actually does. Yamaha did a lot of testing on the Winder before it was introduced and not so much anymore all these little tweaks are developed by Cat and Yamaha does very little testing and usually with old parts.
Did you miss the part where cat has been broke over the last 4 years ? And you still think they had more money than Yamaha to spend on testing the 4 stroke chassis? Cat hasn't even kept up with the motors , they are still on 800cc when everyone has 850cc for multiple years . To each there own .... but there is a reason why they changed their setup ... and it won't be to slow riders down :)

I remember they put a stop on the link that bottom of rear shock is mounted too. So that people wouldnt mistakenly flip that link if suspension was removed. Could that be reason? Maybe only Yamaha did that? Need to look at those skids closely. This just seems nuts.

Maybe so on a Mountain sled but do you think having that #*$&@ end so high is a good thing?
 
On my 2020 I can’t get my a arms completely level unless I loosen the springs past to where they just are sitting on the shock with no tension.

That could be the reason for you over heating more but I didn’t over heat once on my 2020 and I did some long distances riding through towns on minimal snow to get fuel, had some morning where the trail was hard and crisp and still didn’t over heat.
I’m not doubting you just saying my findings with the higher rear end.

Mototown I'm not going to sit and argue with guys on this forum anymore it makes no sense. You think what you want but this suspension change had nothing to do with Yamaha I'm sure they tried to tweak it after they got there hands on it and looked what happens. I also think that Artic Cat is not as bad off as you think, there is a lot of changes being made right now. I'm not sure how this little bit of a change in suspension technology cost a bunch of money seeing how they have had it on there race sleds for years now. Anyways all good.
