Replacing chain with new sprockets question

[burkbuilds]

Just to clarify, this is not on a GZ but on my Vulcan 500. I am planning to change my sprocket ratio on the bike and although I've always heard that you should change the chain when you change the sprockets, it seems logical that this advice is given based on needing to change the sprocket because of wear, not necessarily just because you decided to change ratios. Although I have over 11,000 miles on my chain (520-110link o-ring) I've only needed to adjust it once and only about 1/4 turn to keep it in specs, so it hasn't stretched much and is in really good condition, and I keep it lubed up at least every 500 miles, sometimes more often. A new o-ring chain chain for my bike is expensive, and I'll either have to pay someone to install the master link and flare it or buy a kit which isn't horrible, but it adds up. I'm wondering if I compare the new sprockets to the existing ones, if there's not discernible visible difference in the shape of the teeth and they aren't visibly worn can I re-use this same chain, or am I just asking for trouble? I'd appreciate your input, especially if you actually tried something like this and what your results were good or bad. Thanks.

I just found this little article on the web, this may answer my question, what are your opinions?
