BTW: I should point out I am getting 48.6 MPG highway @75MPH average speed while keeping the head temp down and I have a lot of power. I walk away from stock CVO 110 bikes. The power comes from the fuel add when I accelerate.

 

Will you send me your tune? I'd be interested in looking at it. Either PM or attach to the thread is fine.

 

I would love to but it won't work in your bike. While we are tuning the same things they changed how the ECM functions in 09. You are tuning the same things though the function is just a little different.

 

I'm not looking to run your tune, just study it so I can learn more. Please share. You also have 255 cams and I don't.

 

Ok sure, I pull it down for you. PM me your email.

 

So after re-reading your post I understand that the head temperature reading you are talking about is only with your IR thermometer, at least that's the way I took it. If you're reading head temps that way it would be more accurate if you took the reading at the same point the PV does which is at the back of the head, except you will only be able to get surface temps and not the internal temp the PV reads. Frankly, 250 degree engine (head) temps at speed is nothing to be concerned about and on the other thread you referenced the 261 temps on the 120 weren't out of line either. If head temps bother you get a set of FCS fans. You may not see a huge decrease at speed, but it will lower the head temps when riding in town and when stopped. I actually see my head temps drop significantly when I stop at a light. Jason is constantly working to improve these units and the current models do work at speed. Now if you were seeing oil temps in the 300 degree area that would be something to be concerned about.

 

He has a 350 head temp at speed, at least that is how I read his post. That is hot.

 

i am the OP that referenced a 261 head temp at speed on a 120R. I have a set of Jason's fans ordered for stoplight to stop light riding. The 120R head temp goes up in a hurry stop light to stop light. I am certain my tune and a few other things such as the engine being new are most of the problem, but want the fans anyway

 

Sorry, maybe I was not clear in my original post, at the top of this page... I'll edit it to try and clear it up a bit. If you are referring to the other thread with the 120, it's a different OP.

Using my Power Vision to read the temps, I am at 240 engine temp and 330 Head Temp at cruise speeds. Now, I don't know the difference between engine temp and head temp as it relates to the Power Vision when I have those selected as gauges. Maybe Fuel Moto will chime in. I think this may be where some of the confusion is coming in; some folks are talking Head Temp and some are talking Engine Temp.

To verify that the head temp the Power Vision showed, I used an IR gun on each head at the spark plug.

 

I just email FM before you posted this, so I will let you know if I hear back from them because that is exactly my temps too. 240 oil/engine temp and 320-340 head temp.
