Clutches probably need to be gone through. 10k rental miles? Thats a lot of different butts on the seat every weekend.

I just got a 2020 Gade 600 ace and its freaking awesome. Smooth. What I would call a nice little growl at idle. Nice mpg with close to 20. Wont really know until I hit some legit trails like up in WI or in U.P.

 

I rode a 2015 for 5 years and yes, it sounds like a four wheeler at idle but I could never hear the motor once I got going. As for the vibration, mine was smooth as can be. Funnest sled I ever rode, and I know several guys that own faster sleds that say the same thing.

Oh mine definitely sounds like a 4wheeler too. I think it has a nice lil rumble to it.

 

I agree with you two, it's more like a 4wheeler. But the 900ace is a lot smoother at idle and seems quieter at speed.

 

I've had both the 600 Ace and 900. I agree 600 sounds like a 4 wheeler at idle . The 900 Seems more quiet I think because it's so smooth, it just kind of hums. when accelerating, the 600 is ' lumpier' in its power delivery whereas the 900 is super smooth and just hums as it picks up speed. I don't feel the lumpier 600 power at the handlebars, just smoothness, but I do hear it. I got comparable fuel economy on both the 900 and 600.

Just curious, witch one did you prefer between both? do you feel the weight difference between both on the trail?

I am looking at buying a second one for my wife.

I DO notice the difference in weight and because I do a good amount of boondocking, I switched back to the 600 Ace this year. If I was 90% a trail rider, I would stick with the 900 for it's smooth refined feeling and power. (Not that I don't love the 600!)

 

700renegade ... If the spark plugs haven't been changed in 10,000 mi. I would be changing them. Might help improve your mpg.

 

Definitely something not quite right. I’ve had both the 600 and 900. The 600 doesn’t “sound” great at idle like the 900 does, and has a slight vibration at idle. But once rpm is up enough to move, it’s perfectly smooth. And the 600 would always use less fuel than the 900, unless the 600 was pushed to WOT most of the trip, and then it used the same as a 900, not more.

 

Did you replace the buttons and O-Rings. The factory O-rings will wear out fast and I highly recommend replacing them with the KWI Brand;

Did you align the clutch half's (Factory Marks)?

Thanks for the couple of pointers so far. I've been working 14hr days so not much time to dig in quite yet.

I have a new set of spark plugs to install now, and will look closer at the primary clutch for o-rings and orientation. A couple arms were wore into the towers, and I re-shimmed those to get them swinging free. Can't recall anything about o-rings, but it's been 4 months since i touched it.

I'll probably just pop on a spare clutch to try as a test ( I have a brand new Edrive2 off my 900 plus a used PB80 on the shelf )

 

Throw that PB80 on, slug it for 7600 and call me in the morning

 

I think a PB80 is definitely in my future. I need something just a bit more. Just a touch.

???????? Yeah the pb80 is not a magic pill that turns the 600ace into something it is not. But it is super smooth and does allow for every last HP the 600 (or 900 or 1200) has to offer... in all conditions and 100% of the time.

My edrive really failed at those things. It did a great job maybe 25% of the time.

75% if the time I was lucky to see 7000rpm... so like 50 of the 60 HP.

But to be fair I have a friend with a 600ace renegade that hits the rpms better. So far no pb80 is needed on that sled but it is geared down and has clutching for the mountains in order to work right in Minnesota.

I'm not looking for a cure all, I know what this engine/setup is. Otherwise I would have went 600r.....

But dang it impressed me again today. I love this this machine.

Over 100miles today on NC Illinois ditches/trails from/to the driveway. If it keeps this up I don't have to take any trips. We have great trails here if we get snow.

(No filter just a light adjustment before pic taken, about 15 minutes before I got home tonight, full moon helping too)

 

As usual, Bob may have been onto something.

There was a little play in the Edrive2 towers that I either didn't notice last fall, or thought was acceptable when I went thru the clutch. Paying more attention at idle with the panels open and guard off, I could clearly hear a rattle from the clutch.

I installed a PB80 and the rattle cleared up - I'll need to see if the 2" of snow in the road ditch here is enough to test it out to see if it was the source of the vibration all the way up in RPM.

 

Hopefully the PB80 fixed the issue. The noise and rattling is definitely not characteristic of the 600 ACE. It should be smooth and quiet sounding like an atv as mentioned.

 

The MXZ I rebuilt this last summer had also been a rental. And it had 14,000 miles. Had it on the trail for a couple of runs last winter and, yes it ran rough. Darting, vibrating, and the skis were worn though in places.

The compression was perfect, the oil pressure and coolant - all fine. The engine is sweet. Changed the plugs, oil and filter.

Yes, had the same issues with the clutch arms, worn into the side of the housing and also used washers to bring the arms back to center. Replaced the slider bearings on both clutches along with new springs. The primary was a little sticky the first day out, but quickly loosened before I got it back on the trailer.

The main drive shaft did have a hunk out of one of the drive lugs. Ended up replacing the shaft out of caution with a low mileage one from Ebay.

With what you mentioned about the way it runs, suggest you check the upper boggy wheels. With the rebuilds, finding these are the first places to wear out and will cause a vibration, noise, when they are loose. On another sled that got rebuilt, was the cause of some darting as well. A new set of after market bearings cost almost nothing and are easy to swap out.

In a post on the Cost To Restore, I listed all the bits and parts it took to bring the sled back to new. A fun project and now I have an amazing sled to enjoy. Love the 600 Ace. Seems that when I sled with people with more power, they just throw more snow when they launch. No problem keeping up. And they are constantly stopping to add fuel. :- )

An update on the sled:

I've replaced the spark plugs and swapped in the PB80 clutch with the Cudney kit for secondary helix and spring.

Neither of those two have solved the vibration problem. Just by the cadence of it, it seems like it could be in the track drivers or something similar. I doesn't vibrate at very low speeds or very high speeds.

I've watched it closely running on the stand and see nothing out of round or awry with the driveshaft itself or the drivers. The track clips and drive lugs are fine and I see no damaged studs. My 900 renegade has a studded track and the stud heads make no remarkable noise going around the drivers, so I doubt that is it. All the driveshaft / jackshaft / chaincase bits were inspected and seemed fine when we swapped the track this fall. If this area is the source of the vibration, its almost as if the track pitch doesn't match the driver pitch by some amount. I guess I'd need to swap in a different track to see if that is the origin of the vibration somehow.

 

Did you change the upper chain case bearing ? Chased a noise and vibration , like a stick stuck in the track and it turned out too be the upper chain case bearing , just a little roughness to it upon inspection , change it and smooth as silk

If the track is a 2.86 pitch it's the right one

 

Also have you checked the motor mounts, i know that sounds kind of funny but my buddy picked up one for his kids last year with fairly high mileage, so we went through the whole sled from front to rear before it was ridden. when he finally took it out he told me about a weird sound/feeling from it, when we had it running on the stand under hard acceleration the engine would move significantly. you could move it around 2" with a long bar. we changed out the mounts and everthing was fine, may not be your problem but just offering somewhere else to check. Cheers.

 

700, I may have missed it but I didn't see mention of belt change. Have you tried a known good belt on the sled?
