Here's my two cents.
I'm on my third C50 engine. First one had 80,000+ miles and was running fine when a lady pulled out of a parking lot & clipped the bike. Second one I got to 115,000 miles before the timing chain stretched far enough to skip a tooth. Third one (installed in frame of bike two) I have about 50,000 miles on so far.
I get my oil at Dollar General. Just the cheap store brand 10-40 that doesn't say 'energy conserving' on the back of the bottle. I was getting it at Family Dollar and then one day I noticed their store brand had gone to an 'energy conserving' formulation. I use my bike as my main transportation & commute 100 miles a day, in all kinds of weather, all year long. I change the oil every 3500 miles. I used to change the filter every time; but switched to every other time several years ago.
