What are the symptoms that the belt should be replaced? Is this something I should just do?
I am at about 7500 miles and I ride it fairly hard. I hear some rumbling at acceleration and my brain says that may be the drive belt. But being the only motorcycle I have had with a CVT I'm not certain.
thanks for advice and as I found out after a few posts here....opinions....lol

Ignoring replacement of the belt time risks it breaking and potentially locking up the rear wheel.

Now imagine that scenario when you're riding at any signficant speed.

Belt service consists of belt, roller and sliders. I am still on my original rollers, but I replace my sliders with every belt change (6K mi/10K km). I suspect your rumbling is due to worn sliders.

If it's due, it's due.

And, it is very normal when I change the belt on my MP3 500 that the whole transmission works smoother. Less juddery. Probably due to sanding the variator, and all the new bits that fit to OEM specs. And the new belt not being so smooth after those thousands of miles.

It's due.

Follow the maintemace schedule. Replace the belt et al every 6k miles. You really. never want it to fail.

thanks, I will get it done then. I did try to take a peek at the belt last week and followed a Youtube video but as I was loosening the cover I had oil come out and quickly retightened the cover.
I was a bit confused because I didn't think there should be oil there. Then I read it may be from the filter if it was over oiled. I did have a full service done so maybe. I just need to have a rag ready next time.

Oil coming from the airfilter box is almost always one of 2 things

1) Engine is overfilled. The correct refill qty is 1,5Liter although Piaggio still puts the wrong quantity of 1,7Liter in its literature

2) Excessive airfilter oil. The foam filter only need to be tacky a.k.a. a light coat of filter oil. The foam should never drip.
