Hi, guys. am having this problem with my bike. it's an '08 zx10r with 15,000miles on it. I did 180miles on it and I noticed after 150miles the rpms wouldn't go further than 8k or 9k. It only did this when I ride for long [this is the second time on my return trip it did that.] When I rev it up it struggles to get past 11k rpms. there is a video below of me revving the bike. Anyone else had/heard of this problem and had it fixed? Let me know.
