My GS750 is starting to sound a bit tappety, so thought I`d check out the valve clearances. Unfortunately, my Haynes manual had a run in with an oil tray a couple of weeks ago, and the page I want for the settings is no longer readable !. I seem to recall that the clearance for both inlet and exhaust was 0.030mm-0.080mm, but am not certain. The bike is a 1979 GS750, unsure which model though. Anyway, if anyone can tell me the settings that would be great. Also, any tips for depressing the valves to get the shims out. I have the tool for holding the buckets down, and in the past have used a screwdriver under the cams to lever them, but its a bit tricky on the valves for pots 2 & 3, and I worry about catching the cam lobes and damaging them. Just wondered if there is a special tool for this.

Shimming valves on GS750

Your shim clearance figures are corrrect. You can buy the suzuki shim changing tool from places like sales@z1enterprises.com or through any suzuki agent. They cost around US$25-$30 and are well worth the investment.

Agreed. The shim tool makes the whole thing a breeze. Got mine for under $20 on fleaBay.

Your assumption seems to be that as the valves wear, they get "looser". Its actually the opposite. The more they wear the "tighter" they get. A little noise is probably better than none.
