2008 Valve Adjustment

Just a quick question for people who have done this work themselves, how difficult is it to do the valve adjustment (assuming at least some adjustment is necessary)?

If one chooses not to do it themselves, about what should one reasonably expect to pay to have someone else do it?

If you take it to a shop it will most likely be over $500. If you do it yourself it could be free if there are no adjustments needed

If valve clearance is off you'll need to remove the cams and change out the shims.

And you just check them with a feeler gauge. Only about 6 or 7 bucks at any auto store. If you can find a service manual around here then it will guide you through it easily

I have both service manuals (general and specific). My question regarding doing it oneself is really more along the lines of 'is it a giant pain in the ass?' Isn't there a special tool needed? How easy is it to mess it up? The manual says you have to remove the radiator to remove the cylinder head cover. Is this really the case? If so, it's easily worth $500 to me to let someone else do it.

I did it on a friends 07 600rr and they are more space limited than a gsxr but if you give yourself a whole day or a weekend to come back and forth to it, then you should be fine. And yes you have to only loosen the radiator so it hangs down that way you can wiggle the valve cover out. Personally I would never pay a shop to do it, especially when they will probably charge you the full price whether they make adjustments or not.

Just my 2

I'm at about the 16k mile mark on my '08 and I'm getting ready to wheel it down into the basement for the duration of the winter. My manual says to check the valves at 16k, which I plan to do. Even if it takes me a month, off and on, to check them, order any shims and makes some adjustments it's a whole lot cheaper than paying a shop to do it.

Plus, I don't always trust a shop to do it precisely. On my old FJ1100 Yamaha I took it in for its first inspection, which included valve adjustment. They claimed they did the work. However, on subsequent maintenance intervals I started checking and doing it myself. The first time I had to adjust many valves. Each time after that hardly, if any, of them were out of spec. I question whether the shop even checked them at all.

When I do it I might take a lot longer but I'm not riding the bike over the winter anyway. Plus, when I'm finished I know it has been done right.

this is very similar but different. (very good stuff here!)


i did my 450x this weekend and it wasn't really anything crazy.


when i was a kid i rebuilt an old datsun over head cam motor and was kind of familiar with the cam chain tensioner, timing alignment marks, not dropping stuff in the motor etc.

keep things clean, take your time, you have to be really organized and write stuff down, take pictures if you think you may forget, etc.

after doing the 450 i don't think the 1krr would be to much worse? just wish i could find a video of the gotcha stuff.

In the 2008 service manual they mention using a special tool called tensioner stopper.
Does anyone know what the purpose of the tool is and whether it is really needed?
