ZX11 Valve Adjustment / "Shim"

Couple of questions...

1. I was told by a tech at a local, (Santa Clara, CA), dealer that the valves should be checked/ adjusted every 7500 miles. Does this sound correct?

2. How critical is it that the valves be adjusted/ shimmed at these intervals?

Lol, I just went through this!


YES, you need to have them check/adjusted at 7500 and it is pretty important.

It depends somewhat on your mileage. I would keep to the recommended interval for the first 20,000 miles, then you can extendthe intervals somewhat. I have over 120,000 miles on my 96 ZX-11, and I check them about every 10,000 miles and even then there is seldom any change. Initially the valvesare seating themselves in. As the miles roll on, wear becomes the major factor and this, of course, increases the clearance, which is far less critical.

At least two of the bikes I'm looking at have been "shop" serviced by the book. Based on this, would it be safe to assume, (and I hate to assume ANYTHING), that the shop would have done this as part of the routine maintaince?
