Hello guys,
I am doing a valve adjustment on my 1982 gs 850 L as we speak
question do i turn the engine clock wise or counter clock wise.
second question i just bought a master feeler gauge that goes from
0.0015 in or 0.038 Metric to 0.025 in to 0.635 M can i use this tool to check my cleareance.
thaks for the help guys
 
I go the direction it runs so the starter clutch doesn't drag and you don't created slack in the cam chain..
 
Hi,

As you have your wrench on the right side of the motor, turn it clockwise.

A true metric feeler gauge set should have gauges in increments of .01mm. Most gauges start at .04mm, some start at .03mm. Your spec range is from .03mm to .08mm, but it's OK to run them a little looser, but not larger than 0.10mm.

The set you have should work OK. Just don't get confused between the SAE and metric measurement systems. In inches, the spec is .001 to .003 (that's thousandths of an inch) and in metric the spec is .03 to .08 (that's hundredths of a millimeter).

With the set you have, you may need to combine blades to measure wider clearances, up to .09mm or so.

Have you had a chance to download my valve clearance guide? I've tried to collect all the pertinent information there.


Thank you for your indulgence,

Hello guys,

Valve Adjustment

Valve Adjustment

Hi Nes,

It can get confusing.
As Bikeliff suggested, check out his visual guide it really helps to include his example calculations.


But your next step depends on whether you have adjustable valves or if your bike uses shims. If they are adjustable just adjust them to the .003-.008mm clearance and your done. If like my 1978 GS750 which uses shims, then you need to pull out the each shim in turn and check the thickness of each. Using the numbers you previously got using your gauges add those numbers together and replace the shim with the size you just calculated.

For those that your smallest feeler is too large this means your shim is too thick. For this issue, you can remove the shim, stack the feeler gauges until you get the right measurement and add them together to get the appropriate shim size.
 
Hi Mr. NES07DEZ,

Do you have digital calipers or micrometer to measure your shims with? Sometimes the size markings have been worn off.

If your smallest feeler won't go in, you'll need to drop in a size smaller shim, at least. Depending on how long it's been since the valve clearances have been adjusted, you may need to go down two sizes.

My smallest feeler is .04mm. If that doesn't fit, I drop in a smaller shim. Take an inventory of all your shim sizes and clearances. You'll need to order some new shims. For the best prices see www.z1enterprises.com, or check out the "Shim Club" here in the forum. Some local dealers will carry shims and trade them for free or for a nominal fee.

Now that I've been keeping track of my clearances and shim sizes (thanks to Mr. Steve's handy spreadsheet), it's easy to "guesstimate" what shims I might need for future valve checks. Then I just order what I think I might need ahead of time.

Check out the valve check guide on my website. You will be amazed. :D

Thank you for your indulgence,

BassCliff

Go to your nearest garage, ask them when the Snap on man comes, or get his number, go buy the correct feelergauges from him and they will last you a lifetime, and tell him EXACTLY what sizes you need.
