gspd's valve adjustment technique

[SteveD]

Anyone have it? I can't find it by searching.
Cheers

If my memory serves...
exhaust is 1 flat (of the six) out from 0 clearance,
intake 1/2 flat out.
I think the thread pitch is 1.0 mm or 40 thou.
1/6 = 7 thou
1/12 = 3.5 thou.

(now help me with my f*****g carb problem.)

Is it really such a hassle to use a feeler gauge? The hardest part is removing those two tiny nuts.
Gotta make that Allen screw conversion some day.

You remove your nuts to do a valve adjustment?

It keeps his mind from wandering.

I have a valve stem that's a little mushroomed at it's end, and it makes using the feelers a little less accurate. Just exploring the alternatives.

I will get the 2 inlet valves replaced this year. I have 2 nice shiny Intervalves on my bench ready and waiting.

intake 1/2 flat out.

Thanks dougie. Can gspd please confirm dougie's memory?

Hi Steve, I actually printed a copy of his post:

1/12 of a turn (1/2 flat) out from snug is 0.08mm
slightly more than that is fine for the intakes
1/6 of a turn (one flat) out from snug=0.16mm
slightly less than that is 00.15mm about right for exhausts

Running the valves alittle tighter just means more frequent checks.
The tighter the valves, the quieter and smoother it will run.
Tight is not a problem as long as there is some clearance.

Thank you. I'll save it myself I think.

Matt, you got a (local) source for those screws?
