Hot weather vs cold weather

[Charlie1Horse]

When it's hot (summer) my 92 GL1500 Interstate will run rough when accelerating from about 1200 to 1500+ rpm like when coming out of a turn from a corner. But when it gets cold, below 50 degrees for our 3.5 days of winter, it runs very well and smooth at that acceleration. Is there a sensor that monitors the ambient temperature when it gets hot weather to keep it from running badly?

Those who say it cannot be done should try not to interrupt those who are doing it.

I'm not the most knowledgeable person for this topic, but here's what little I do know.

The 1500 is carburated, right? I think this means it is affected by temperature more than the fuel injected models like my 1800. For combustion engines in general, when it is cold they make more horsepower. I can't articulate why, but remember that for whatever reason they do. So, when the temperature is hot they make less and 1200-1500 rpm is a little on the low side for a Wing. Although, it is something of a torque monster, for a bike this heavy I don't expect much pull at those lower rpms in any temperature. However, it will pull better in the cold just because of that horsepower thing.

One of the experts will be along shortly. Hopefully!

There is an intake air temp sensor and a coolant temp sensor for the ECM. (At least in 1994) I do not know what the software does with that info as to engine management settings.

Cold air is more dense. Like going down in altitude.

In certain places on very hot days some models of helicopters can't fly. It's like reaching their altitude limit.

The usual problem with a 1500 is lean running and the symptoms would be compounded in cooler weather, yours is doing the opposite. Coming out of a corner with leaning involved when the problem appears with yours? Nothing on the MC would know or be affected by a leaned over condition except maybe fuel level in the bowls. If fuel level is a little high in hot weather it could richen the mixture enough to stumble it, then in cooler weather when an engine could use a little more it sucks it up running good. Is your engine mat in place? Check that the hot air door in air cleaner snorkel is open in hot weather which allows outside air into engine. With engine hot at idle after a good run, stand MC straight up then let it drop by itself having the kickstand break the fall, any RPM change/stumble?

In Phoenix, Arizona, the commercial air traffic is shut down at 127*F on the tarmac.

the Density Altitude is so high, the airlines cannot clear the mountains on take off going east, and going west they can't get above the metro area above minimum FAA rules for ground clearance....

If they had any kind of minor power issue, they would crash into the high rise buildings in downtown Phoenix.
