Just brought my ZR7 in for valve adjust. It had 25,000 km on it and I've put on 5,000km of them.
Three of the exhaust valves were so tight that even the 1/1,000th blade wouldn't fit. I was told however the buckets would spin so there were still closing.
Because of the inablilty to measure they had to guess the shims and remeasure and then take apart and install corrected shim sizes. This ended up with much more labour charge......$600! for valve adj and carb balancing.
The shop said that it's extremely likely the valves have never been adjusted before.
Bike is running fine now....question is ...how often is the recommended valve adjust.
