engine to hot
2007 RK- 103 BB, woods cam tw6-6, big sucker2, Rinehart TD exhuast, jagg 10 row oil cooler, amsoil, Tmax w/AT. my basic map selection was done by bore, exhaust, intake size. I've tried setting from 12.5 to 13.5 AFR.
problem- when crusing at 50mph or less engine temp increase to 300'c before I shut bike off( usually in about 10-15 minutes).
traffic just makes it worst, if that possible.
at speeds 60-85mph engine seems to hold around 270'C.
i included some plug photos, about 4k miles on them, 1k after the cam change.
could this a timing problem, since engine ran cooler with original 255se cams(no where near as strong)?

RE: engine to hot
It looks as though you are running to lean, valves not seating or improper ignition timing. When I put my cams in the springs were bottoming out and had to go to different size springs. You might just need to have it dynoed to check your A/F mixture to make sure its correct. Good luck
