Who really gets their valves done at 16-18k

[RIPPIN LIPS]

My question is who really gets their vavles done at or around 18k. I have a 05 liter bike with 18,600 on it and recently took it to the local Honda shop here in Dallas and the shop tech told me that I didn't need it. That thoes bikes were never off and it would be a waste of money. Thought that kinda funny considering most shops want as much money as they can suck outta ya. What kinda of benifits would it have on the performance of the bike if any or would I even notice?

had 34k on my last 05 1krr with no valve adjustments before I sold it.

I was told by Honda here in SA by me that only once it battles to start I can have it done . Till then , no worries . A waste of money .

you should have them checked, but 9 times out of 10 you dont really NEED anything done until the 30k mark (under normal riding conditions).

Basically, I skip that service on my bikes. My faith and confidence in the service department is extremely low. People's experience is that few, if any, adjustments are actually done. So I take my chances with not taking it in for this service. I do all my routine maintenance, but valve adjustment is beyond my ability and desire.

I have an FJR with 30k miles, a ZX 14 with 18k miles, and my CBR has 5k miles. I had a VFR with 12k miles. None has had its valve clearance checked. I had a BMW with 24k miles a few years ago and I had it checked - they bent a valve and screwed it up. I learned my lesson.

One more thing, I buy my bikes new, I am the only one that rides them, and I don't do track days. All items in my favor.

My shop spent a few years racing one, and I know they're competent, so I just let them do whatever they think is necessary. My ZX6R had about 40k miles on it, and when it was checked it needed no adjustment, FWIW.

Now one thing I do insist on or around the second service, is that they strip the front and rear end to regrease it. The Japanese are not very generous with their factory grease IME.

When I had my '08 engine rebuilt, 9 out of the 16 total were out of spec. This happened at 12,000 miles.

But why was your engine needing a rebuild?

Compression loss in cylinders #1 # #3 due to excessive oil consumption. My tech also found:

Inconsistent valve seat machining (several of the seats were non-concentric).
Broken steel backing of cam chain guide "A".
Excessive deposits on the backs of the intake valves & in the combustion chambers.
Signs of blow-by on the piston sides (due to both bad ring design and material).
Scuffing in cylinder walls 1 & 3.

But at least the bottom end of the engine was good. We rebuilt it with JE pistons, degreed the cams and added higher compression with some considerable custom headwork. Been beating on it since this past spring and even though the oil burning hasn't been completely eliminated, for the kick-ass performance I'm getting it's well within acceptable limits for me.

I would tear it down to the valves and close it back, just i dont know how to addjust valve!never done that!
