renfro - I'd like to hear how this worked out, or how it is working out. The idle mixture screw should really only make a difference at idle (and just off idle). I think if you read just a little way into the 'Rebel AFR' thread, to the point where I post graphs, you'll understand how your bike's AFR vary from the factory. And if you keep that in your mind when messing with your bike, you'll probably have one great running bike.
If your bike is an '86 and can hit 70 mph, it's not far off. Mine maxes out at 72 mph (flat, level, no wind, sitting upright) and mine is a 2016. The speedometer reads 75ish, but GPS verifies that's 72 mph.

Your 86 may look like mine if the brass plug sealing the AF screw in hasn't been removed
if you find a plug drill a small hole tap in a small screw and pull plug out

Where is the Fuel/Air Mixture Screw?
There may be a simple answer to this question, but Iâ€™ve searched everywhere. I just bought my â€˜86 Rebel 250 and it was running extremely poorly. It idled decently, but wouldnâ€™t go above 55 on a good day. The throttle got really boggy at higher RPMs and wouldnâ€™t allow me to keep up with traffic.
I pulled out the carb, took everything apart, and cleaned the entire thing (the injectors and all). It runs much better now, allowing me to get up to 70 easily. I adjusted the idle stop screw (the one with the black plastic head on the right side of the carb next to the throttle cables).
Problem is Iâ€™m still having a bit of issues at higher speeds/RPMs (still better than before). After reading some forums, I found out my bike is probably running rich, so I should adjust my air/fuel mix?
Iâ€™ve searched for days and canâ€™t find out where the darn air/fuel screw is. I read that itâ€™s on the left side/underneath, and is a flathead screw? Iâ€™ve also seen that itâ€™s got a tab over it so that you canâ€™t easily adjust it (due to EPA standards).
Please help! Iâ€™ve got a big trip ahead of me and Iâ€™m really needing to get this adjusted.
