When skint I ran my 500/4 chain that bad on the rear sprockett - went from like the gold alloy one above to toothless in very few miles, and I had to knock a few links out too, glad I now have a proper contract rather than a 0 hours one as I did then. One thing I love about the sohc in line 4's is how smooth they are and how little stress this in turn places on chains - despite the abuse of knocking a link out of a worn chain, I've never had one fail, on my 125 and 250, they have both snapped chains well before it reaches the adjusters end or the sprocketts looked badly hooked.
