OK, here is the latest. I popped the caps off the pilot screws and tried adjusting them. On the front cylinder I got NO speed up at all, but did get a decrease in RPMs (no tach, just going by ear) when the screw was almost all the way in. On the back cyl, I got NO change in RPM at all from all the way in to all the way out.

I ran each pilot screw all the way in and backed them out 2 1/2 turns and then backed each out an additional 1/2 turn (3 turns in all). Went for a ride and it ran like crap, popping, bucking, hesitating. Came back and tried the complete adjusting procedure again, still the same, no change in RPMs. I re seated the screws and backed them out 2 1/2 turns zactly. Went for another ride and it ran better/smoother especially at lower RPMs. Still popping alot especially on decel.

I am going to wait to run a couple more tanks through and then if no improvement, I guess I'll have to pull the carbs and clean them.

2 questions: Will the popping hurt anything?

Where does one order the carb rebuild kits?

BTW, on the temperature difference, the front cyl is only slightly hotter than the back. Not significant (I don't have an infared thermometer).
