@Wdaniels, as mentioned above, if you really want to spend your money & time on things like this, go ahead and get a belt guard;
OR, do what
@ned64 and
many, MANY other riders have done without
ANY issues, and just go without.
Sure, now that you know your belt is a little damaged, keep an eye on it, check it regularly, saaay, once a month or so; I'd even suggest that you should now closely inspect both the front and rear sprockets to make sure that the teeth haven't been damaged, and if you find any chips, stones, or nicks, carefully remove &/or file them out; then ride on!
We've got far more dirt, gravel, and chip-seal roads here in my part of Oz than we do sealed roads, so if you want to ride anywhere truly interesting, you pretty much
HAVE to ride off the sealed stuff; and I've seen quite a few Spyders that've done well over 100,000 km without a belt guard and without any issues. I've even seen a few Spyders that've worn out their belts, some with the odd hole &/or nick in them too, for many tens of thousands of kms, and I can assure you that these belts can stand up to a helluva lot more damage than most here seem to think, AND that it takes a helluva lot of km to wear them out too!!
So don't sweat the small stuff - check your belt & sprockets out properly, the keep an eye on things as you rack up the miles; but really, just...
Ride More, Worry Less!!
