My CB400 has just reached 60,000K and has been serviced regularly but I,m now starting to get multiple issues such as it,s on the 3rd water pump & still leaking. Today while on the freeway at 100k,s I lost the speedo it just started to go to zero and jump up & down. This afternoon coming home I had no speedo at all. Has anyone else had similar issues with a CB400? I,m getting a little desperate now as I feel it is falling apart for no reason. Look forward to any assistance or solutions available!
