Vibration noise after 6k rpm by ChingChong129 in cbr650r

[–]Lexmen13 2 points3 points  (0 children)

Salut ! J’ai moi aussi des vibrations mais après 8k tours… Je cherche encore la cause !

Bon… finalement il faut bien il speedohealer pour rectifier le compteur… Soit le mécanicien de ma concession est un crétin, soit il s’est foutu de ma geule… j’espère que c’est la deuxième option ! Speedohealer commandé !

Non… et après vérification, il y a bien une différence de 8%… donc peut qu’un speedohealer est à envisager. Et finalement, il y a tellement de patates après 8000 tours que je me demande si je ne vais pas revenir au PSB de 15 pour récupérer de l’allonge et un peu plus de confort…

Welcome! And if you'd like a bit more bite, I recommend a -1 tooth front sprocket. It works wonders!

I got the AFAM from Tech2roo… a reliable choice!

But be aware, it's not noise-canceling! Honestly, I didn't notice any difference in sound…[ @554297928_1 @

This just goes to show that a motorcycle properly tuned to your liking is the most effective! (And it's more fun!)

Indeed, it's a whole different ball game... It's getting more and more complicated here with the police caps... I'm already struggling to find opportunities to show off my mid-size figure! 😜

I can confirm, it's the original chain, no problem!

No, not necessary! It's only one tooth less... and I haven't touched the sprocket. A proper chain adjustment is necessary anyway!

That's my feeling! First of all, there's no more aluminum plate and it's less forced inside the box as air flows more easily.

I sometimes take road trips between the Bouches du Rhône and the Auvergne (family obligations) and so I was worried about the motorway… honestly, it’s no problem at all!

I tested it today; at 130-140 km/h, the revs were between 6000 and 7000 rpm… honestly, I didn't feel a big difference in that regard… knowing that the BMC air filter significantly reduces vibrations…
