I just bought a 1980 KZ440 all original with only 3,000 kilometers from the original owner and everything seems fine, except that one upper header pipe is somewhat bluish while the other has a more yellowish color.
The seller told he it has been stored since new but that he would start it regularly and that he may have "overheated" it. Iím thinking that one cylinder may have been running a bit hot (too lean?) and the carbs may be out of sync too. I donít know if the headers are double walled and/or prone to discoloration or not. I know lots of older Triumphís and BMW's have this happen. He recently bought a new battery and had the carbs removed and cleaned.
He says both header pipes were fine looking until he ran it stationary for an extended time. He says he was not aware that bikes did not like being run without moving. I did not explain about convection doing itís job at idle, (at least under certain circumstances etc).
I rode it for an hour on the highway and it runs surprisingly well except that the idle is a bit too low and there might be a bit more vibration than should be. The mirrors at 100 kilometers per hour get blurry.
Mind you, I have a 2004 Honda VFR ABS, and the 1980 KZ440 LTD I bought to help my wife learn the basics, so I can't comment on what other KZ440ís perform like, but I know it's an old twin - collector plate coming!
If you have any suggestions on how to bring about the best in this beast as it relates to carburetors, ignition, valves, etc, I'm all ears. I wonder if I can use the carb specs posted as per the below URL for the "1977 Lincoln KZ 400 D4" or does anyone know the setup specs specific to a 1980 KZ 440? I do have the actual owners manual.
Also I guess I need an air filter, oil filter, spark plugs, ignition point set and inline fuel filter? I have a Morgan Carbtune II for syncing and most other good stuff! I am not exactly sure what the OEM Kawasaki part numbers are and/or non OEM cross references are.
Also anyone know a good wrecker in the Vancouver BC Canada area as I need a new right front brake lever and maybe some mirrors that are less vibration prone.
Much thanks & cheers,
I did find this site and posted, there is lots of good info there, but it's a bit early to know it will pan out http://www.armbell.com/forum/index.php?mforum=kz400
