The popping at idle and deceleration (when the throttle is in the idle position) could be a lean mixture at idle.
A lean mixture sitting at idle for a long light would cause the engine to run hot.
Also, as the engine reaches operating temperatures, the idle will pick up.

if a clutch is bad it dont choose to be good in hot or cold, maybe it is the trans going bad as it warms up

This is usually down to clutch adjustment.If the bike shifts into neutral at stand still but doesn't when hot then your clutch cable needs adjusting so you have 1/8th of an inch freeplay at the lever. Also try running on a 20/50 oil as these bikes weren't designed to run on synthetic oils( clutch slip ) Also warm the bike up properly before a ride , don't tear off with the engine cold. Happy riding.

Been running mine now for 36,000 miles on Castrol GTX 10W40, and have had no problems!

Old fluid or improper type. Doesn't the Sporty use the SportTrans fluid in the year? Other than that, maybe time for new clutch plates. Or the clutch spring may have lost it's spring.

after the bike has warmed up, then reset the idle to approx 1000rpm. then see what happens when its cold. some bikes are cold blooded and the use of choke is necessary for a bit, at least until it warms up...

Keep in mind that a wet clutch requires special oil and adequate free play to make sure the clutch is fully engaged. Chk both. Regular engine oil wreaks havoc on wet clutches. good luck

Your clutch plates have lasted 25 years. It is probably time to get some new plates. Have your dealer get you a set of Barnett clutch plates.

Hi Al,
I know you are looking for feedback and I hope I can help.
I have a FLHR Road King Harley Davidson and believe me It clunked real bad when I bought it (7,000 miles), I checked the clutch primary chain, well within tolerance, also Clutch plates too.
I know your engine is wet sump and the gearbox uses the same oil as the engine?
I changed my gearbox oil and also double checked level as the amount that came out wasn't enough?
Since then pure smooth cold & Hot, so maybe the wrong viscosity oil? Nice & Thick cold but when thinned due to warm up and at operating temp not coating the gears so bulk rings failing slightly?
There you go one to look at?
