What do they mean by valve adjustment?

Hey guys. I called a Kawasaki dealer near me to see if they could do the 600 mile service and they said that it would be $180 without a valve adjustment, and $280 with the valve adjustment. What would be the purpose of a valve adjustment?

Since motorcycles run such high rpm's the valves need to be adjusted. The adjustment is how they seat, the slightest bit of the valves not seating properly can cause performance and other issues leading to motor damage. At 600 miles though, they really don't need adjusting. I believe they deff do by 15k miles.

Your bike should not need a valve adjustment. No where near. They are trying to pull one on you lol. Should be good til 30-40k km

actually, a valve clearance check is part of the 600 mile maintenance.

Everyone should believe in something, I believe I'll have another BEER.

Not according to my service manual for an '05 636.

Vavle clearance doens't get checked until 15k miles. Is it a 250 thing?

That’s why I specified my model and asked if it’s a 250 thing. I didn't think it would be any different.

It maybe a 250 thing, smaller motor with high rpm's. Which I do believe they call for a valve check, not adjustment. Unless you are experiencing any problems, I wouldn't worry about that.

There is a specific range of values that dictate what the clearance should be between the valves and lifters, or cam lobes in some cases, too tight or too loose and you will lose performance. Check your owner's manual to see what it recommends for a 600 mile service. If you don't have one you can download it from the Kawasaki website.

I have 15600 miles on my 250r and never touched my valves yet, engine runs perfectly but I think i'm going to do the clearance check at 16k. I'm sure they'll be at service limit, but my point is that I've never felt a loose of power on all powerband. I run my bike every day as commuter and one - two times a month in race track, oil change every 5000k miles (Motul 300v full synth)
