My '07 has 32,600 miles and runs great. Should I get the valves adjusted before next riding season?
Is this something I can do?

Agree that MOST don't... However, that means that SOME do (mine did; I checked them myself at 34k and two were out of range). They may or may not have been set up right during assembly. Do you like to gamble?Don't waste your time or money. Most motorcycles don't need valve adjustments for many more miles then you have on yours.
I am not a technician, but I will share what I know metals. the valves are steel, and the heads are aluminum, after the steel valves slam into the softer aluminum heads for a while they seat themselves into the aluminum which changes the original adjustments. If they are adjusted on the higher end of the spec at the factory, the seating action should not put them out of spec, but, if they are closer to the lower end of the spec from the factory, they most likely will need adjusting. The shims are hardened steel, they do not get the wear, the type of oil does not matter as far as valve wear goes, as long as they are getting oil the shims will not wear enough to matter. As far as adjusting them ever 100,00 miles go, the engine will still run with the valves out of spec, but it does run a little better with them adjusted within spec.If I understand correctly the valves require shims and the only reason for shims would be due to wear and I can't see that if you have always ran full synthetic oil that you would have enough wear to require adjustment at 32K. Would someone with more technical knowledge on this engine give more input. I knew one rider that did an adjustment every 100K and he was at 341,000 trouble free miles. I guess I question shops that always seem to make adjustments. If you are a technician willing to share honest information please do. Thanks
If I did I'd own a Harley. :lol: If your experienced enough to check them yourself then go for it but most who would have to take it to a shop would be wasting their money for those miles. Japanese bikes are built very well. Will a Honda dealer even sell shims?Agree that MOST don't... However, that means that SOME do (mine did; I checked them myself at 34k and two were out of range). They may or may not have been set up right during assembly. Do you like to gamble?
Hal sell's them, some Honda shops have an exchange system, usually about $3 or $4 plus your old shim, You can order them from the dealer, but from my experence, they cost about twice as much as Hal sells them for. There are also kits you can buy with an assortment of sizes, but it would not be cost effective for 5 shims and you would end up with a box full of shims that you will most likely never use.Checked mine to-day @ 32000 miles. Five valves are out of spec. Where is the best place to get shims?
