I ran the bike in with the stock head and was running the green spring so difficult say TBH. I fitted the Stars head and yellow spring which immediately woke it up! From feedback of other riders on KTMForum, it improves low down torque and pulls hard through the rev range, which it does!
No problems with overheating, but then it's been freezing or just above freezing when I have been out.
