Does anyone have any instructions for setting the rear mono ride height and sag? The owners manual is WORTHLESS. They used to sell a set-up manual for the Pro-Action I'm not sure about the Mono. If anyone has any info can you please post.
Thanks
Thanks
No problem, here's the procedure Yamaha gave their dealers at their service update school:
Hang the sled and measure the spring, then sit on it and measure again. You want about 40~45mm of sag. If you're bigger than average the max cam adjustment might not get you enough preload in which case you'll have to move the circlip that holds the preload cam.
According to Yamaha the 40~45mm of sag is same for any mono and any spring and rider weight so pretty easy to follow.

Thanks t787 did they give any measurements for the front shocks?
No but my experience is leave 'em alone until you can ride and see how the sled handles. They won't affect ride quality as much as they'll change handling becasue you're changing ski pressure and also ride height.
Ski spring settings can be tricky, for instance lots of people will increase preload to get beter bite in corners which it does, but it raises the front of the sled so now you have higher CG. That and the ability to turn harder increases body roll and ski lift. So now you're back to turning problems.
I learned this the hard way in '03 when Yama told dealers to reduce front preload to reduce body roll ('03 RX-1s were known for it). I was skeptical, seemed like softening the spring would make things worse but damn if it didn't work!
I'd leave it alone until you see how it goes on the snow. If ride comfort is your concern, get the rear dialed in and leave the front alone. Probably be just fine stock.
Good luck.
