    So basically, I was working from the Kawasaki service manual and the details for balancing were quite brief. Reading the Haynes manual introduced the concept of restricting the gauges and when I took the throttle bodies off and saw the difference in hole size for the gauge feeds I thought it's got to be that that was causing the issue. The later models have dedicated vacuum feeds for each body , so I'm guessing that anyone balancing those wouldn't have the same issue. The gauges I bought didn't come with instructions and there were no restrictors in the tubes, it was only by finding instructions for other gauges that I found I needed to cut each hose in half and insert the restrictor! Why they didn't come like this from the factory I'll never know. Never mind, we live and learn!

    Ah! Well done Foxy, this is good info for any other Z owners willing to take on this maintenance work.

    Glad you got it sorted and it wasn't something larger like burned valve seat etc..

    I salute you for your perseverance !!

    Thanks for the feedback Chaps, It was certainly a learning experience and I reckon I spent around 5 days in total  :005: but this was down to checking and rechecking after the spurious vacuum reading!

    Like most things in life, the more you do something, the better you get and I think I could probably now do the plugs, shims, oil service and throttle balance on this model within a day.

    One useful tip when changing the plugs was to make sure you put a universal joint directly attached to the plug socket and then add the extension to that (instead of putting the extension on the plug socket and the UJ on the extension) a small change but this made plug removal and fittings much more accessible   :028:
