Hello everyone,

Been reading about all of these rattle/ticking sounds that the MT07/R7 engines like to make! My bike is no exception.

I'm getting 3 different noises:

1. Once the bike warms up there's a distinct tapping sound that increases with RPMs. It sounds quite a bit like valvetrain noise, as if the valves/tappets are out of spec. I've owned my 22 R7 since new and started noticing it after the first 50-100km (got 1700km now)
   
   
2. Under deceleration or light throttle between 3-4k RPM I am getting a metallic rattle/jingle noise from the front of the bike. Almost sounds like the bike isn't in gear properly and plates are clashing with each other & engine is struggling a bit?
   
   
3. On gear shifts I'm also getting a metallic rattle noise.

Took it to the dealer at 1,000km and they said the slight rattle/ticking when the engine is idling is normal for these types of engines.

The noise that worries me the most is the metallic rattle/jingle noise mentioned in the 2nd point above. Mainly noticeable when upshifting from 2nd to 3rd-4th gear (at lower RPM)

Appreciate any advice, thank you.

The sound is normal at idle, mine does the same exact thing. Also I’ve noticed it when riding too, but only when my face shield is closed. I think it’s just the noise that the engine makes combined with the sound frequency that happens to make it through my helmet. Either way I haven’t really worried about it, and I haven’t noticed any problems shifting or accelerating whatsoever. Just get a nice exhaust so you don’t hear it😂

I get the rattle noise at extremely low speeds in 1st & 2nd but that that is literally it.

Same here, it's just the cross plane motor that Yamaha uses. The R1 is a cross plane 4 and has that ticking or knocking also.....if it was a serious knock. It'd be louder and harder and would cause a lot of damage lol it wouldnt last that long

Same here, noticed it in my helmet and was driving me nuts. Then I noticed when I turned my head or looked down it went away. Just the perfect frequency that is coming into the bottom of helmet and getting amplified. Wish I knew exactly where that jingle was coming from. Has to be something buzzing.

Most likely what you are hearing is the cam chain rattling. This is a pretty common issue on many late model motorcycle engines and the solution is to install an aftermarket manual cam chain tensioner, problem solved!!!
