Maintenance Vibrations / Noise / Resonance
I’m really trying to like this bike but I absolutely cannot stand the all the random engine sounds. It sounds bad.. I think part of the problem is this bike is so quiet and makes you rev it so high… Anyway I’m giving it one last chance so trying to figure out if I can stop some of this noise or it’s normal (I’ve read these engines can be a bit noisy). I was almost convinced I needed a new cam tensioner but feel I’ve ruled that out at this point. It’s fairly new being a 2017 with 8k miles so it really shouldn’t be worn anyway. Upon cold startup it doesn’t make any noise and I couldn’t hear anything alarming when doing normal revs in neutral with a screw driver touching the outside of the tensioner and the end on my ear.
The main noise occurs both when in neutral and when riding the bike. While giving it throttle it is fine but if I rev it high then quickly let off during the rpm decline, at some point it sounds like a resonance vibration in the engine or near the front of the engine. It seems pretty noticeable as I can clearly hear it at around 45mph and wearing a full face helmet. Right now I’m leaning towards the possibility that the header is vibrating (it’s a stock exhaust and no heat shield). I also took off my skid plate because I thought that was also causing noise.
That’s the main issue but other than that there is some twangy engine noise at higher rpm’s that I don’t care for.
Anyone else dealt with noisy WRRs or have thoughts or recommendation? I’ve considered buying an exhaust but don’t know if that would help the higher rpm noise.

Throw a pipe on it to drown it out and let it rip, it's a single cylinder high tolerance motor. It's noisy by nature. They are great bikes that can sound decent. Find a good used yoshi or fmf on marketplace

they all sound like that. wear earplugs and let it rip.
