It's just not my month

[NAKID]

So, after the near miss with the timing belt last week I've been keeping a closer eye on everything. The chain I have is about 5K miles old. I saw a couple spots that didn't quite look right. Upon closer inspection, I have 2 o rings missing from a couple different endplates. Not only that, but one of the two screws that hold the top plastic swingarm guard is a bit beat up. Nothing looks out of place and I can't find any play in either the CS or rear sprocket. What's going on?

I've seen a few chains that have shucked O-rings, usually they're pretty well worn out by that point.

Possibly the chain is hitting the bolt head due to the guide/runner surface being worn down.

[NAKID]

Possibly. The missing o rings are on that side.
I did eat a chain before I replaced it with this one. Maybe it chewed up the guide. Where can I order one?

And realistically, how bad off am i with no o rings on those plates?

sorry to hear it NAKID, must be something in the water.... I just went through a headache myself. I just hit the 50k+ mark and:

1) My dust seal on the clutch master dry rotted out, replaced with a Yoyodyne part.
2) The 21mm cap for the oil screen mesh filter was rounded out thanks to the last shop that used an impact wrench on hot aluminum. In the process of replacing the cap, the "Thermistor" temp sensor broke. *do NOT over tighten this part*
3) Getting everything back together and looking over everything just to find rear tire has 10psi... nail. (but ok needed new tires anyway)
4) Lastly, still dealing with the splines on the output shaft wearing abnormally allowing the front sprocket to drift off center. Getting an old sprocket machined to act as a spacer for the fix.

Now that I've hit higher mileage, I'm looking over and double checking everything a little more carefully.

AFAIK, the guide is a dealer only part
I've not seen any aftermarket.

Those chain links will die quickly, as with no O-rings the grease (that's in there when the chain is assembled at the factory) escapes.

Of course...

I'm on the same boat. I've ran over 3 nails (1 Front, 2 Rear) in less than two months and had a bee stung me on the face when I was riding lol  . Also noticed missing nuts on my exhaust.

I've been keeping a close eye on my bike too. Sometimes I feel like I'm riding on a grenade.

Nakid - give this some attention. I noticed that my chain tension would not hold, and found that the plate which holds the front sprocket in place was worn out. It has teeth which match the splines on the output shaft, and the plate is obviously the wear item. It's a cheap maintenance part from the dealer. If it wears out like mine it allows the front sproket to move laterally on the output shaft...not good.

Though not the same issue as Skurvy (thankfully), it's a part often overlooked.

BTW what is chain brand? Regina?

It's one of the first things I checked. No play whatsoever on the CS or rear sprocket.

Chain I beleive is a DID. Can't remember really.
-edit- Just looked, it's an RK
