    Anybody ever swap in a Doo 600RS R-Motion 137?

    By the pictures, Red. Package isn't due in for a few more days. BTW, no shocks. So I have to figure this out as well. I'm reading on dootalk that the front shock length is the same as a standard R-Motion. But the rear shock isn't. Thanks,

    Anybody ever swap in a Doo 600RS R-Motion 137?

    Found a cheap Doo 600RS R-Motion 137 rear end pretty cheap and bought it without much thought. Then after buying it realized it was for the MXZ 600RS racing sled. It's not the same as a standard R-Motion 137. Anyone ever swap one of these into an 06 Apex GT or 03 RX1? I imagine anything is...

    Poor handling 06 Apex GT.

    I expected to delete that empty post. The sled is toed out almost a 1/4 inch.

    Poor handling 06 Apex GT.

    Update to this. Completely loosened the mono shock spring. This was more difficult that you'd think. The spring someone installed is so firm that even that with almost zero preload the sled barely travels. I also misidentified the spring. While I can't read the middle numbers the last three...

    Poor handling 06 Apex GT.

    Just did about 15 min of ditch banging some pretty lumpy snow. Not even close to bottoming. It could definitely be softened up a bit. Otherwise it seems acceptable. A lot of low speed steering effort. I’m gonna guess it’s the skis. I also added the shims. They measured about 5/32. So...

    Poor handling 06 Apex GT.

    Cool. Coupling rod adjustments are easy. I have Bergstrums shim in the stocks skis. I’ll see how thick they are. With the talk of the rear springs I went out and looked for markings on the spring. Being almost 20 years old I suspected the spring may have already been replaced. Other...

    Poor handling 06 Apex GT.

    Thanks for the replies. Busy day. I did have a problem with the sled during the test ride I didn’t mention. The sled would completely power off for about a second and come right back. Started doing it so much I was thinking it might die in the woods. It also started simply hunting off at...

    Poor handling 06 Apex GT.

    Last spring I bought a used 06 Apex GT. It was in pretty good shape. Needed both driver bearings. But I went thru pretty much everything. From donuts to valves, to all shocks rebuilt, all bearing and rebuilt rear skid. The entire suspension is all set back to stock except for the rear...
