1987 Suzuki GS450 - running again; tuning commences

Thanks Rich. I was wondering if an air leak was the issue. Reorder will be on its way. I've looked but none of the diagrams I've seen include the choke lever that'd I'd like to keep.

Go to the hardware store and buy a 4 mm screw and washer. Put a little Locktite on it if you need to.

Your wandering idle is caused by a leak in your intake boots. Either the boots themselves, or the orings between them and the head - best to just order all new parts from Japan. As far as that screw goes, sometimes you can find the thread pitch and length on a parts diagram.

Link to oring reorder? I had it but I can't seem to find it again.

Google Robert Barr or cycleorings first. Then try any online parts business - partzilla, bikebandit, etc.
