Hub 4 was exactly what I was thinking. Re 2 I also wondered did they tell him before he just stopped by they pulled the head without removing the engine?

Granted 1 is per Kaw service manual and generally I'd say go by the book. But it surprised me engine needed to come out unless there were bottom side bolts or something. Seems fairly odd. Suppose it's like throttle bodies and removing valve cover it IS possible (as Rook demonstrated) to remove valve cover without removing tbs. Having done it a few times now pulling throttle bodies is a 5 minute ordeal out & in.

I spoke with the machinist. He expects to take a look at the head this week; been backlogged with other work. He has over 30 years of experiece going back to the Z1. I got a good feeling after talking with him that the head is in good hands. His first thoughts, other than this not making any sense, is the stem is mushroomed and/or the face/seat relationship is receeding. In either case he won't know until he disassembles the head and checks clearances. I will make a trip this week to his shop to see with my own eyes and hear his explanation.

The original estimate of $2k was based on pulling the head based on flat rate and service manual procedure complete from beginning to end. It was just a starting point to get the estimate started. The hourly rate, I believe, is $105/hr.

The carbon buildup on the pistons is even. My neighbor who is knowledgable in all things engines said it was nothing to be concerned about.

As always.... stay tuned. In the meantime I got my BMW running after more than 10 years of neglect. Need to sync the carbs today. Fun stuff, and much easier to work on than the ZX14.

Thanks for the update. Sounds like you will get competent work done but it might cost a bit. I'd rather pay more and know it's right.

Excellent idea guys. I could always use a few more horses. Let's see, if each member donates a dollar...
How do I establish a port 'n polish fund? Tax free of course.
