Ray and Brad,
This is an interesting theory about the location of the air temp sensor. I've always wondered why it is mounted on the intake if the sensor is actually designed to read ambient outside temp. At speed I wounder if the air passing thru the air box actually has enough time to heat up to the temp of the air box [caused by motor heat] or if it actually is reading ambient temp [I would think the amount of air being passed thru does not actually heat up to the engine temp.]. Also I wounder if the temp sensor actually reads the ambient air temp or is affected by the temp of the metal airbox instead of the actual air temp.
I have a Hypercharger, stock but de-baffled exhaust and a Cobra TFI set at 3,4,0. The bike has never pinged on 93 or 89 fuel [I've never tried 87] even before I added the Cobra. When I added the Hypercharger I installed the Cobra "just in case" and it has improved my throttle response however the best gas mileage I've gotten is around 38-39 mpg and buddies riding behind me say my exhaust smells rich. I still will get a low idle stumble if I set the idle below 1000 rpm. My plugs look just right, nice golden tan to brown electrodes. I do have the exhaust reed valves removed and get no popping on deceleration at all.
Brad you said that as the air temp goes up the ECU wants to make the bike leaner. With this in mind, having the air temp sensor reading a lower temp should make the bike run richer as you said.
Just looking for comments about this and different opinions.
