I pulled Mine last summer and were in the 50/50 range Could change or leave, and two were CLOSE but still not there YET. I don't want to keep taking it apart to check. Do you have ROUGH estimate and how fast they wear??? Travel Safe! Travel Well! Mark (W. Mi.) [Non-text portions of this message have been removed]

The shims, themselves, don't wear at all, per se, but the valve does and becomes what some discribe as a "pizza cutter" - thin / sharp edge. The pre-08 valves were to be checked in the first 5,000-6,000 miles. I think that the post-07 valves are longer lived and are to be checked at 10,000 miles. My inspections on my '06 indicate that it took about 10,000 miles to go from max clearance to the minimum on the new engine but then that "gap shrinkage" process slowed down. I continued to check it about every 5,000-6,000 miles anyway to bring the clearance up to max when I can. The engine has 30,000 on it now and sometimes I don't have enough gap shrinkage to fit the next thinner shim in. I have 6 more shim sizes (thinner) to go before I have to start over with new valves.

That gives me an idea on how long before RE-opening to recheck them. 2 were close to min and 2 were not close enough so I'll wait untill 5000 after last check. SYMPTOMS of too worn?? (below min.) Fred has singles, OR A KIT of assorted, If I remember right? (asking you here fred instead of directly, so others also get to KNOW.)

If you are asking what symptoms you would have with the valve clearance too tight, you would notice hard starting, power would be down some and it would get worse as it warms up. You won t hear any valve ticking like you would with valve clearance too loose. A valve clearance that is too tight could burn the valve and seat from excess heat. Valves cool themselves by the duration of contact with the valve seat where the heat is taken away to the head and coolant. Valves too tight won t contact the seat long enough to dissipate heat and will get very hot. Remember a tappy valve is a happy valve . (no, I didn t make this up) Yes, I sell individual shims and a shim assortment. There are advantages and disadvantages to both. Your choice.

I think the factory recommendation to wait 10,000 miles before checking is bad advice. The old recommendation was to check them at 500-1000 mi. and then every 6000 after that. When the '08s first came out, a lot of KLR owners, doubting Thomases that they are, went ahead and checked their valves at 600-1000 miles, just as if it was an older KLR. Just like the pre-08s, a significant number were found to have valves out of spec. In addition to catching valve that are out of spec from the factory, checking them early gives two more advantages. 1) You can set tthem to the top of the range, to give the maximum time before an adjustment is needed, and 2) you will know what your clearances are and what shims you have in there (write it down somewhere), so that you can make an informed guess as to what shims to have on hand the next time. Of course, if you wait 35,000 miles for your next valve check, as I did, you will have lost your notes, but you will learn for yourself that once bedded in, your valve clearances will be quite stable for a long time.

Other symptoms you might notice are an irregular idle, a tendency to stall on the overrun, i.e. as you slow down to a stop, usually just as you pull the clutch lever, and stumbling while moving off from a stop.

I agree with Jud. In a perfect world, where you could 100% count on the factory to have every valve set at the max clearance when you receive the bike, you could probably count on 10,000 miles before needing to re-shim but the best practice would be to check the clearances early on just to make sure that you have a good starting point (max clearance). After the first time, and if there is enough gap-shrinkage to allow you re-establish that max clearance in all 4 valves again, I'd feel comfortable going 10,000 miles before checking again. Again, you see the fastest gap shrinkage (wear of the valve/seat) during those first 1,000-3,000 miles and as wear continues it assumes an asymptotic curve until valve/seat replacement or failure. With me, I put 6,000-7,000 miles on each year so I check them annually and sometimes I can slide a thinner shim in and sometime not and it might only be for one valve. Don R100, A6F
