Title: Belt Wear
Post by CoyoteJosh on 10/09/13 at 16:44:43

I purchased a new 2013 S40 just over two months ago. As of today I have just over 3,100 miles on it, and noticed that there are some marks on the belt that look like it is being chewed up a little. I guess I am just wondering if this is normal wear and tear, or if this could be an indicator of a bigger problem such as the belt not being aligned properly. I did a search and couldn't find anything on this topic, so I took some pictures and have attached them along with links to higher resolution images.

Thank you

I couldn't attach images until I had one regular post, so here they are.

Thanks again.

Just a guess but did you feel the edges of each part of the sprockets to see if one is sharp or has a protrusion that's causing the marks?

Do you ride regularly on a gravel road? Looks like stone damage to me.

Look at the pulleys & see if theres any rough spots that will continue to chew on the belt.

Too tight a belt setting, on pulleys that are not polished smooth. Guys, that is NORMAL for a new Savage, the stealership invariably sets the belt too tight. Mine was set so tight that I aired out the front tire and popped both fork seals 5 minutes into owning the bike.

The pulley and belt have to wear into each other, running the belt looser will prevent the chipping and gouging, yet still allow for them to mate up. Harley belt drives are the same way, ditto Yamaha and Kawasaki (even the old KZ440 and 750B parallel twins).

The road that I live on actually switches from pavement to gravel about a quarter of a mile before I get to my driveway. That would make a lot of sense if that were the cause. I will investigate the pulleys tomorrow for rough spots when it's light out.

If those look fine it's more than likely from the gravel, which would be unavoidable I suppose.

Thanks for the prompt and helpful replies.

Also, the roads I ride between work and school throughout the day have been getting resurfaced, and when I try to take alternate routes I just hit more roads that are being resurfaced (I know, in Minnesota there's two seasons; Winter and Road Construction). I did notice that about two weeks ago there was a lot of loose chunks of road being flung up at me, and a larger one hit the bottom of my bike making a loud thud. I didn't notice much if any wear on the belt before school started back up and I was hitting the construction.

I'll also perform the board recommended belt tension 90 degree test tomorrow, just to ensure that this isn't the case.
