8k, interesting.
I thought the restrictor kicks in at 5k. as that's where the bike makes 33hp:
My bike feels pretty dead at 8k.
As for the temperature, this was at the same speed, in the same gear, on a flat. Could have been the trees affecting it. I've not noticed it doing it before, and I haven't been anywhere on my bike since then.
I'll have to check it next time I ride it, Which will be 16th October - Hogging the Bridge.
Anyone else coming? I went last year on my 125 and it was really good, not to mention its for a good cause.
