I have to play with my throttle position stop screw while riding. I usually have to up the rpm's when cold, but as bike warms up I have to back it off to keep the rpm's from going too high. Then after riding a while, rpm's tend to drop so I adjust it back up. I try to keep it around 800-1000 rpm when idling. No tach so I'm guessing, of course. You can usually tell when it's idling too fast or too slow. You may also be running a little lean. OK at idle because carb gets more gas normally during warmup. Especially if you have the "fuel enrichment valve" engaged. Not to mention the nationwide heat wave tends to affect how the engine runs. Maybe turn your mixture screw out 1/4 turn, see if that helps any. As far as the fluid on the chrome? You should be able to smell if it's gas or oil. You may have a small oil leak going on and it's blowing back as you ride. If it's fuel, I would replace the lines right away. Real cheap and you don't want raw fuel misting onto your HOT motor. Also, you may want to check the vacuum lines to the petcock, if you still use OE one. A small vacuum leak will cause a low idle, same as running too lean. Now on the other hand, how many miles ya got , and when was carb last rebuilt and/or cleaned internally? Maybe that's all it needs.
