So, this may just be all in my head but recently my FZ started doing this weird "bobbing" thing every couple meters. It's not losing power or suddenly accelerating (or at least neither of the two to a significant extent), I'm not hearing any weird noises from the engine etc, but once i start moving it's as if i keep riding over small bumps. At first I thought it was just bad roads, but then i started noticing it on the hiway, which, for the most part is pretty even.
She had a valve service last month (at the dealership), oil changed and chain lubricated last week (by me), tyres are pretty much brand new (2 months max, installed etc at the dealership), chain and sprocket are fine. The only thing i can think of are the spark plugs, but that isn't due to change for another 3k km. It's probably worth noting i have an ejk (m4 exhaust) so she's running richer than stock. Below is a small clip i recorded this evening. You may be able to see what i mean better.
Things to note 1.) the knocking noise @ 0:12-0:16 is caused by my helmet strap flapping against my helmet (forgot to buckle it, pulling over shortly after i realized lol)
2.) @0:18 i go over an ACTUAL bump in the road
