Chain wore though the rubber guide and damaged my fecking swingarm (not to bad mind).......ordered a new guide, 2x new sprockets, a 14 front and a 42 rear, + a heavy duty O-Ring chain, gonna try that mod with the silicone under the guide, heard you can also use like a bike innertube??, just fold it up and clip it under the guide, nip it down at the screw points?????? Is the idea to raise the guide a little in the middle to stop the chain slapping about so much?? just wanna clear it up, should have it tomorrow morning. Also why do supermoto chains slap about so much? Never seen a bike chain move about as much as this one does!!??
