Question about 2003 Harley Davidson FLSTS Heritage Springer

1 Answer

Mechanical question

I have braided throttle cables, and it seems like every 3500-4000 miles, they stretch at the carb linkage. This creates way too much play in the throttle. Any tips on how to prevent this? Adding this after several responses- 1)They are Harley cables. 2) I did not install them, or adjust them. They were installed by the Harley dealer when I purchased the bike. 3) I had them replaced at the Harley Dealer under my extended warranty once already

That's interesting, I have run throttle cables for many years with minimal stretching. Are you tightening the lock nut at the adjustment? And are you sure you have the cables adjusted properly? Specifically the return cable, if it is too tight it will conflict with the primary cable, this will cause the primary cable to (over time) pull on and eventually stretch the return cable. Try loosening the return cable, then with the throttle wide open ,tighten the return until it has just "a hair" of free play. Then adjust the throttle to where it has just a very small amount of free play ,then tighten the lock nuts. Then check to be sure the return cable has some play when the throttle is closed and if necessary re-adjust.

hi sounds like the main spindle shaft that operates the carbs has seized spray penetrating oil wd40 or similar all over the outside of the carbs giving them a good soaking leave for a good few hours

After complete dissassembly and cleaning of

Try taking the return spring out and give it about an additional one inch of length by gently stretching it out. Over time, the spring can loose some of its original tension.
Even the smallest debris particle can cause the throttle slide to hang up. If it isn't foreign matter causing it to stick, then there could be a ding or gouge in either the slide or the carburetor body. Take the slide out and put some blue machinists dye on it, then slide it up and down inside the carb - this will show you where any high spots are. Carefully remove the high spots with 1,500 grit wet or dry sandpaper.

Throttle sticks at full

Sounds like the return spring got squashed. Take the top off of the carb, free up the spring and, if it isn't broken, reassemble carefully.
Try it afterwards, if it still sticks it could be the cable.

Idles at full throttle

Be sure the throttle cable is routed correctly and is not being stretched. When disconnected from the carb, does the inner throttle cable operate freely? Lubricate it. Also check that the cable connections at throttle and carb are seated properly. Does the slide move up and down freely? Remove the air filter and twist the throttle while looking inside the throat of the carb. LIGHTLY seat the throttle screw and the air screw then open each of them one and one half turns outward.
