'82 GS650G Project

First off, 1&4 fire together and 2&3. Switching 3&4 sounds dangerous. Please don't do that.

If you haven't already done it, go into your profile and turn on "view signatures", then check out mine. It contains a list of common problems for new owners, a carb rebuild tutorial, which it seems you need, and a source for carb O-rings.

BTW, the engine sounds fine, other than the misfire.
BTW2, the EX500 master cylinder is the wrong size. You need a 5/8" bore master. Try the EX650 master cylinder, the rectangular master type, which has a mirror boss. Those are good units.

Would you mind taking a look at my conversions from feeler gauge size to mm for me? Like I mentioned above, just looking for confirmation or denial before I move on from this.

"Okay, so I managed to check the clearances between the shim and the camshaft lobe according to the 8 valve guide you supplied me with. The .0015" feeler fit under all of them so no gaps are under .03 mm (roughly) and the .003" feeler fit under all of them so no gaps is larger than .07 mm (roughly). The .004" didn't fit under any.

Am I right in believing this is within spec? It should be within .03 mm to .08 mm right? If so that's good that I don't have to swap shims but I was hoping it could be related to cyl 3 misfire."

.03-.08mm is the spec, but it's perfectly safe running up to .12mm.

Excellent. Thank you for the confirmation.
