I'm in the process of changing the drive belt.  Everything I've read says to rebuild the variator at the same time.  Has anyone had any experience with this.  What weight size is best. The bike has about 15,000 miles on it and I should have changed the belt at about 10 - 12,000 miles.  There are no out side cogs on the belt anymore.  Thanks for input.

According to the folks around here Dr. Pully's replacements are the bee's knees. Here's a link to what they think you should be doing. http://www.drpulley.info/drpulley_docs/Typenliste.pdf

Thanks for the input.  I'll look into it.  That X10 is a good looking bike.

Thanks. I'm, actually, starting to enjoy it. We had a rough start.

Check with the folks at
www.scooterwest.com
they were helpful for me in recommending
the proper weight for my application.
The fellows at
www.buggypartsnw.com
can also be helpful about Dr Pulley parts.

Got around to changing the belt, rollers and slides.  I used a set of DR. Pulley rollers.  Now at idle, I'm pretty sure I hear them.  I don't remember hearing a noise like that when it was new.  Has anyone else experienced anything like that.  I think the bike still performs as it did, my wife thinks it is quicker from a start.

The 1st time I heard one of those doing that I pulled wide in case it wanted to throw a rod or worse.

Had the same noise on my 2008 400 and never had a problem.

That doesn't sound correct. I've fitted Dr Pulley sliders to a lot of scooters, from 125s, 250s, 650s and if fitted correctly, they shouldn't be doing that - as far as I am aware.

On the other hand, I do know that if the variator's slide pieces (some have 3, some 4) are worn then one experiences the phenomenon that you describe.

If the nylon slide-guides are worn out, then you will have
metal-on-metal....& possibly a rattling sound.

They're complaining about having to work overtime to support your claim about yellow being the fastest color.
