Nice. I see it has had a few "additions" Same as mine except mine is a dark metallic green. It is in fact a non o-ring chain, if it is stock, and to convert to an o-ring chain, you have to go up one tooth on the countershaft sprocket. I'm sticking with non o-ring chains. I'll see how long the stock one lasts. There are better quality non o-ring chains out there than what came on it. They can last a long time if you keep them maintained

IIRC, there is a narrower o-ring chain available which doesn't require the sprocket change, but the quality of that chain was questioned.  Am I remembering correctly?

Most who switch to o-ring go for quality name brand chains, which seem to be too wide for the engine casting, and thus the need for the sprocket change to accommodate.
