quick valve opinion

just checked mine the are within spec still each having .002 left to grind off, they are wearing evenly each wearing .001 in the last 7k miles, just wondering if i should go ahead and adjust them or wait a while longer. i have been noticing that at low rpm in a higher gear i get a lot of tinking. any thoughts? obviously other than watching which gear i am in (which i have been)

The motor runs better when the valves are set to the max. tolerances, starts easier also.

so new shims are in bike runs, also had to change out my chain and rear sprocket...again on my trip i had to adjust the chain ever 100 miles on the way back, stretched a total of 2 links :| not impressed, it also wore the rear sprocket to sharp points, wouldnt have gotten much more out of it.so got it all buttoned up everything in place tightened up and it dawns on me. i forgot to clip the radiator fan wire back in.....smh sometimes i am such a noob. oh well i will tear it down again tomorrow, already pushed it too far today and my back and hip is paying for it.

ok got everything plugged in and took it for about a 20 mile spin. engine feels tight and strong. only thing i noticed was it seems to want to overheat. only happens after i stop after going for a while, the fan doesnt let it get too hot but it gets hotter than i remember it doing before, any thoughts? is that from having new tight exhaust valves?

Did you drain any coolant? If so maybe you have an air bubble in the lines. Start it up with the radiator cap off and let it run for awhile. Squeezing the hoses helps sometimes to get a bubble out also (running, cap off).

You adjusted your valves for more clearance (not tighter) yes?

I'm attempting to adjust the valves on my 09 klr.. I found an online calculator that returns the following when I put in my current clearance/shims:



My questions:

1) does this look right for an 09? ..the site says it is for 84-05, but I thought all were the same on the inside?

2) the right exhaust clearance was a somewhat loose .008", but a VERY tight .009"; if I put it in as .009" the calc tells me to not change that shim, and the calculated clearance is a closer match to the suggested shim for the left exhaust... should I opt for matching left-to-right (only change the left), or change both and get closest to the loose end of spec?

3) are the new shims something I can find at any moto shop, or are they specific to the KLR? Locally I have an independent (mostly BMW) mechanic, in the next closest town there is a Honda dealer, about 50 mi to Suzuki, KTM, Triumph, etc, and about 150 mi to the nearest Kawi dealer.

Thanks!

As far as I know the valve clearance specs have not changed.

Since you are in this far I'd set to the loose end of the spec on all.

These same shims (29mm) were used in the BMW K model bikes.

Gray-haired riders donít get that way from pure luck.

Thanks for the quick reply... I'll be calling the local shop as soon as they open (..it 5:30am here).
