1981 gs450 Air mixture screw

[jaymechie]

Hello,
desperately trying to find where to find a air mixture screw replacement for my '81 GS450. I've tried a '83 450, '81 1150 and neither of those work. i even started ordering random air mixture screws on amazon to see if any of them would work. any suggestions??

Can you post a photo + a sketch, with detailed dimensions. Some calipers needed to measure.

6 years ago, out of curiosity , I removed a 650 mixture screw and made this sketch. Two years ago, I got some off an eBay guy …..they were well made.

That's impressive. I may have to do that cause Ive got no luck so far

Each carb should have its own pilot screw. Why can't you remove the screw from the other carb and measure that?
