Question about Harley Davidson FLHR Road king Motorcycles
Was out for a ride bike was popping and acting strange. went to put the throttle on and got nothing. At one point while I was out the bike raced when I was coming to to a stop. ?????
You didn't say what MODEL YEAR you're talking about, as it could make a difference!
If it's a 2008 or newer, they did away with the throttle cables on Touring models (like the Road King family) and went with Throttle-By-Wire, which uses electric sensors instead.

Hey Tom, gonna try and help ya here...typical vapor lock/overheating is what your describing and i sure hear a lot of it w/harleys...are you using a very high grade synthetic oil , like castrol Syntec Actevo ? are you filling up w/ premium gasoline ?
make sure your timing is not too far advanced and don;'t let it idle too low...when you come to a stoplight stand up for a strech while letting your engine get air not blocked by your legs....all these things will help greatly......Good luck to you friend...Tim

ALWAYS have a fire extinguisher on hand when working on carburetors.
Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Now pull the top cap off the throat of the carb and remove the large slide. There will be a long needle in the center of the slide. Remove the needle and then move the clip at the top on the needle down one notch. Two notches may be required but start with one notch. Put it all back together and try it out. Moving the clip downward richens the low end fuel mix.
A “very helpful” rating for this answer? Thanks!

This is an air problem. You have an air leak(s) between the carb(s) and the cylinder. This leans the fuel mix and causes the racing problem. Rubber / plastic seals, "o" rings and manifold ducts get old and cracked and just don't seal well at the clamps any more.

Your problem sounds like fuel starvation for sure, You will probably find your float or float inlet needle and seat valve is sticking or the float level is set too low.in the carburator bowl. another possibility is the filter sive in the fuel on off valve is blocked, start your check there, it is an easy fix, look at the on off valve and remove the bowl on the bottom. look inside and remove the sive filter, should only take 5 nimutes to fix. make sure the fuel runs out and not just drips when the valve is open. The carbs are a little more complicated.
