That "surging" sensation
I've got a 94 KLR 650 that has been experiencing what I can only describe as "surging". The RPMs stay constant, the idle is not rising or falling, but the bike lurches intermittently. Anyone have an idea what might cause this?
I suspect it's a worn out drive train and maybe it's time for new cog, sprocket and chain, but I'm not sure. Is there an easy way to check this myself (there aren't any signs of "sharks teeth" on the sprocket). Or if it's something else entirely where should i go from here?
