I don't intend to get to the valve clearance service within the warranty period, 3 years. I'll be right on it as the warranty runs out, then I'll do it myself.
Meantime I'll be doing 4k ones because they're easier to remember. So, 4,8,12 and then the valves at 16 ensuring that it doesn't go over 14,500 before that warranty expires.
I do 8k services on my zx6, it requires 4k ones (valves at 8k(so I do 8 then valves at 16)). It's been fine. I have a mate who has the same bike, he performs 10k services, valves at 20k. It's on nearly 60,000 miles now and the last time he did the valves (at 54k) all was well. Modern oils make this possible, dealers need to catch up.
