Just woundering, does anyone view or visit this forum? My KLR has a knocking noise from Idle to just about 3100 rpm. Could this be caused by the CDI unit or KACR unit? After reaching 3100 rpm the engine smooths out and runs like a bat out of heck.
'Sounds' to me like you need to do some 'research', on the engine balancer chain 'lock lever'. aka 'doo-hickey'.We'll fiddle sticks! My 96 has the same issue, a loud knock at low rpm, intermittent. I thought maybe it could be my throttle cable knocking against something when it was slack. Hoping it's not a valve issue because of my exhaust. Pretty much just straight open,,,
