Question 01 Road King runs rough when hot.

Bike runs good until it gets hot, or around 20 miles of riding time. Spits,coughs, sputters. But will idle good. Was told it was the crank sensor. After reading on here I don't think so. I changed the plugs, no help. I think something is breaking down maybe plug wires, coil I have no idea. Any suggestions would be helpful. It is fuel injected.

Is it fuel injected. If so try cleaning the iac sensor with some mass air flow spray cleaner. Do not use wd-40

if good low speed operation, rough high speed operation think that fuel is not getting through full flow.

which could be a clogged filter. ( but this would be hot or cold)

check that, if carbed check float level too.
