[Fixed] Will not rev past 8k

[positron]

That filter does not look like it was changed last year.
....
New OEM filter is white  and you can see light through it  :lol

Wow. I have a note here from February this year saying the mechanic changed air filter. That's just crazy. Is he duping me? I thought he's a nice honest lad. I will have to pull out the receipt and double check. I really hope it was a mistake from my part.

Seeing bike has already done 70k+ miles, would a K&N air filter be kinda aspirational? Def not getting hiflow air filter based on the experiences here #

The said note I had somewhere (it's not much, but may be you guys get a laugh out of it, figures are in EURO not Sterling)
