Anyone have any prob. in this area, mine is in the shop now, so i don't know what the found yet.

Mine was hot too, i also had problems with running it below 3000rpms. i got a tips from the badweatherbikers forum to get the EBR racing ECU.
Now my 08 1125R is smooth down to below 2000rpms and the cooling temperature has falled with about 10 degrees. It is one of the best investment you can do to a 1125R, i think it costs about 250 USD from eric buell racing.

I also have over heating only when riding through town stop start stop start at to manys lights. My X1 2001 Lightin gets to hot and won't idle gets very ruff.
