apex monoshock skid adjusting yamaha guru's?

[X-APE]

Please tell me how to increase center track pressure, or in other words, decrease ski pressure without adjusting the front ski springs. On a conventional skid this is as easy as simply tightening the center shock spring. Anyone? I have heavy steering and plenty of front end sit in. I also have a loose rear and poor traction. I need more center force. Please dont say let out limiter strap, that wont do it. I need more spring force to center only. This has to involve repositioning a bolt or pivot point. Or, is this is a major downfall of the monoshock skid? Help?

What length carbides are you running?

I have 8 inchers on my GT and i think it steers easy!

Are you riding on good snow conditions?

You gotta wait till the suspension gets a few miles on it & the snow has a base & gets set up. Can,t set up anything for early season soft mushy snow with no base. Track can,t bite & all you get is spinning & lotsa weight on the front skiis.

I understand that, but my other sled side by side went fine in the same conditions. ??

There isn't any way to reduce the ski pressure. If you want a lighter feel to the steering it has to be done by changing carbides/skis.

If you wanted more pressure you can shorten the limiter and it helps (more effect while accelerating than cruising obviously).

This was my main complaint about my 05 early last season also.

However... Once I put some miles on it, new carbides, the heavy duty mono-spring, shortened the limiter, etc. I was 100% happy with the ride from the mono-suspension. In my case I wanted more ski pressure, especially while accelerating out of corners.

Assuming you have an ER model, see page 8-26 of your owners manual for instruction of how to change your weight transfer. If your dog ate the manual, it's vailable online at http://www.yamaha-motor.com/sport/service/viewmanuals/viewmanuals.aspx?ls=sport

While this skid is new to me as well, I'd work with the control rod to address the issues described in your post.

Hope this helps

Sorry, its got nothing to do with the x-fer rod. Its the lack of center track pressure, on any other susp you can simply tighten the center shock spring and problem is solved.

A few simple things you could try:

- adjusting the handlebars towards the rear will make you sit farther back and reduce the weight on the skis

- filling up the trunk (remove the heavy stuff from the front bag if you have one)

- add a trunk bag and throw stuff you want to bring with you in it (sweater, handle bar gauntlets, spare mits, all the maps, tow rope for your buddies, etc.)

I still think you'll find this isn't a problem when you get in better conditions and put some miles on the machine, but you are 100% correct - there is no way to adjust the suspension for less ski pressure or increased front/center of track pressure.

well I need to do something about the heavy steering and loose rear my apex is exhibiting.

This is what I will try; The front end already sits in about 3 inches of its total travel under its own weight so I would rather not further loosen the ski shock preload. I'll try that at as last resort.

Rather, I will try to let the limiter on center arm out one position, and add more monoshock spring pressure hoping the increased pressure will put more downward pressure on the center arm which in turn should take some of the load off the skiis.

I think this will work and will make the sled easier to steer with less hand/wrist fatigue on tight trails as well as increased traction on loose snow..

I experimented quite a bit with mine last season and found loosening and increasing the front end preload didn't really make any difference to the steering "feel".

I believe that lowering the front actually increased the weight on the skis (but not by much).

I think the best advice is ride it some more in decent conditions before you make any changes. I wouldn't be surprised if you find your OK with the cruising ski pressure and that there's almost too much weight transfer (and it's easily adjusted to your preference).

Also, on my 05 I found lengthening the limiter made the sled really squirly under moderate acceleration. Tightening it improved the stability drastically. The Apex is a different sled, but I suspect if you go too loose you'll have the same general trend.
