Engine Operating Temp - Should I be concerned?
I posted the following question in the touring section and although most said the engine temp was normal, it was suggested I post the question here because the engine temp reading from my PV may be too high. What do you think? Do I need to make changes to the tuning to bring down the temps? Thanks for any info. Original post:
Bike is a 13' RGC with FullSac Sportpipe, recored mufflers, SE Intake and a PV with 3 or 4 auto tune runs and I run Redline in all 3 holes. I know the newer bikes run hot but I expected the PV tuner to bring the temps down some. Went for a very short ride yesterday with the following numbers: Outside temps were around 95* give or take a couple degrees. Ride was about 10 miles long on surface streets with 4 or 5 red lights along the way and speeds around 45mph. Power Vision was reading engine temp as high as 305* at about 7 or 8 miles into the trip. Bike runs good but these temps continue to concern me. I guess I expected after tuning the bike with the PV, the bike would run cooler than it does. More in the 275* range. Any cause for concern here or is this the norm?

Sounds like you don't have the EITMS (Extended Idle Temp. Management System) turned on. It helps limit the temp rise.
You can check/adjust it with the PV.
-Set ON/OFF under Limits & Switches
-Set ON/OFF temps under Environment
Mine is set to 284 deg. ON/275 deg. off. It generally keeps temps under 290-300 deg.
My cruising temps went down with Stage 1/Stage 2 changes, FM 2-1-2 header and PV. Idle temps stayed about the same.
I only run Synthetic oil in these bikes. Its less likely to break down under high temp conditions. I like the extra margin.

Looking at several data runs I did in Georgia during the summer (most of them with OAT in the low 90's), one of the higher records indicated an air intake temp of 140* and engine temp of only 246* at the end of a run of about 40 minutes, a distance of 21 miles (with stop lights and signs), and then sitting in my driveway, getting off the bike, opening the TP, and stopping the computer.
IMHO, I think your figures are a bit high.
