My IAT reads insanely high. We were riding around in mid 60s weather this weekend. I saw over 100 on the AT display! Moving the IAT is not a new idea. People have been doing this on cars for quite a while. My GTO forum (new-style) all move the IAT to a place that more accurately measures the temp of the air the engine is breathing. Do we have reason to believe the air COOLS down inside the box before inhalation? If so, that would probably trigger the ECM to richen the mixture. ac | ||

For those of us that don't have a manual where is the IAT located now? I would like to se the difference if I but it in the intake itself. | ||
| Avc8130 |
The IAT is located in the intake "snorkel" between the radiators, under the lower triple. Look just above your front header from the front of the bike. You will see the sensor sitting in the 1"x5" intake. ac | ||
| Joshinga |
well if its a already in the intake what would be a more appropriate place to put it? | ||
| Avc8130 |
The theory is that the actually injested air may be cooler than the air infront of the snorkel. Not sure I believe it either. ac | ||
| Ratsmc |
There is more to it than that. The bikes run really lean even if the IAT is reading accurately. If it were moved to a cooler spot, it should richen the mixture. | ||
| Avc8130 |
Oh, so the idea is not to make it "accurately" measure the "actual" air injested...but measure some cooler air. Interesting. I doubt you could cause damage. ac | ||
| Joshinga |
so I pose the question again what would be the best place to put it to get the coolest air? | ||
| Avc8130 |
Hmm...the airflow for the radiators supposedly enters through the pods, goes in between the frame rails and out under the tail. The passenger seat gets warm during operation. I guess anywhere not in that stream would be better. ac | ||
| Joshinga |
so one would assume that the cleanest coolest air would be right at the beginning of the pods. To me that would be the the best place for untainted air. | ||
| Avc8130 |
Sure...until the fans kick on and all heck breaks loose. ac | ||
| Captain_america |
Extend the wires and put it on top of your helmet  | ||
| Joshinga |
so do the fans causes air to blow out the front of the pod or the sides? | ||
| Captain_america |
The fans suck the air through the front of the pods and out through the inside towards the intake "snorkel", "duct", "Tract", ...... | ||
| Joshinga |
so if you put the IAT at the front of the pod it should not be affected by the fans. right? | ||
| Captain_america |
Right. I will see where the wires will "let" the sensor be located without extending them today at lunch. | ||
| Joshinga |
groovy. I was gonna do as I sit around doing nothing all day but I let you do it.  | ||
| Captain_america |
Pshhh. If your not busy ..... haha | ||

I think y'all will find that if you put the inner airbox on, the IAT will display VERY close to the right temperature. The inner really affects the amount and velocity of air going by the sensor and into the motor. Over 50 mph, my IAT is 1 or 2 degrees within ambient. IMO, this is a bigger reason to keep the inner than a loss of Ram Air. Z | ||
| Joshinga |
well ill do it to and whoever gets to it first posts | ||
| Captain_america |
Deal... | ||
| D_adams |
Mine's usually accurate to within 1-2 degrees also, especially if I'm moving more than 30 mph. Under that it will go higher, but not real bad. | ||
| Captain_america |
Mine has never been correct, air box on or off | ||

IMO, you guys might just be wasting your time. At least with cars, your moving the iat somewhere under the hood that is trapping heat unevenly, making the search for cooler air a little more fruitful. I'm still interested to see what you guys come up with, but IMO the difference will be negligible at best. | ||
| Captain_america |
Here is what I saw as the best thing to do with the short wire that's there....    Hey who knows what will happen... But by 8am tomorrow , I will  | ||
| Joshinga |
Ok thats not gonna work just tried it where you have it in the pic and I got temps of 85-100 degrees where as before it was between 71-75 degrees. But I did figure out why! Apparently in that position the fork tube and fairing create a air pocket or void if you will that keep the clean air from getting a direct shot at the sensor. now this my be different on the CR due to the smaller Fly screen. Also I noticed that the bracket you have it tucked under gets HOT so there may be some radiant heat issues in play to. As for now my conclusion is that the IAT has to be in direct line of clean cool air for this experiment to be affective. | ||
| Joshinga |
By the way I will tear down the pod on that side to see if there is a way to route it. | ||
| Captain_america |
Your right Josh... There is an air pocket there. BUT, I did find this out: 1. At low speeds (under 55mph) it does display cooler. It showed between 70-82 degrees even sitting idle at a stop light. 2. Sensor in the stock location showed between 80-102 unless above 55mph then it would sit around 82-95. Rolled home this afternoon around 6pm and the IAT showed 95 and the thermometer outside said 68! 3. With the sensor in that spot I could feel the heat there with no glove on. And if I cupped my hand to grab some fresh air the temp would instantly lower by 5-9 degrees. 4. I'm gonna by a thermometer and put it on the bar clamp tomorrow to get a definite comparison and I am going to make a wire extension tomorrow and tape that bitch to the top of the pod (IAT). Either way my bike was runnin sweet today. Accidentally did a fat burnout in second on the free way haha. | ||
| Joshinga |
Captain... I mine went up at slow speeds I think that the fairing difference is the issue there with the R the bigger fairing traps the heat and the CR like yours doesn't have that issue. | ||

All else being equal, a higher viscosity oil will create more parasitic loss of power, so the 20W60 would be a poor choice if increased power is a concern. A good quality 10W40 synthetic would improve efficiency by a significant amount. Most racing machines use a W30 grade synthetic for just this reason. The theory about foam building inside the crankcase is interesting and sounds plausible. Interesting discussion. |
