Modern Vespa

So, I shouldn't blame the shop for the Dayco belt. I ride hard, & if I just puttered around town, I'm sure it would have been fine. Anyway, my old belt was within spec, the shop here said it was in good shape. I replaced it because the previous owner didn't know the service history. The old belt doesn't have any directional arrows on it & the guys at the shop said it would be fine, whether I reinstall it the same way or not. I can't miss any work, so I have to go with it. Any of ya'll faced with this belt direction delimma?? There's not a flat side either

If the belt is installed the right direction, I think you should be able to read the printing when it's on the bike.

I don't think any amount of hard riding should result in belt failure at 2000 miles (from your other post). My understanding is that even on the Scooter Cannonball Run belts go longer than that. Are you sure you installed it correctly?

Gates say

If a Dayco belt on a GT 200 failed at 2000 miles, it's not the belt, no matter how hard you think you beat that thing. There are people who really know how to beat a scooter, and they couldn't get a correctly installed belt to break that soon. Trust me, you have no idea what "riding hard," is on a GT200.

this is from another thread You have not "discovered" that Dayco belts are bad. What you have "discovered" is that when don't put things back together correctly, they break.
