Exactly. There's a couple of people who are using cbr650r (2019) dipsticks in the older models to achieve exactly that.
I wouldn't, but it seems to be working OK for them.

CB650F Top End Rattle
- Thread starter Arthur45
- Start date
Back to the original topic but this 'rattle can' noise is really starting to annoy me. It dominates every ride and doesn't ease off as the engine gets warm. What 'exactly' is it that rattles so much ? The bike still has 6 months Honda warranty to run and I presume removing anything from the engine would invalidate the warranty !?
can you record it?
top end rattle is pretty normal on 4 cylinder bikes. but rattle at idling can be of loose parts. send the file to me directly. [email protected]

I had a rattle, the horn bolt was loose on my CBR650-F.
My friend's R6 rattled too, one of the exhaust header bolt/washer thing was loose.
Check those areas.
Good luck.

Hey, i don't know if it will help you but i had a similair problem recently, i drove for about 700km one day, and i put earplugs when i ride, so i don't know exactly when the rattling started, but once i got home, i could hear this rattle as soon as i rev it, my Bike is a 2018 CB650F and it was still on factory warranty, so i took it to the dealer who checked it for a couple of things before finding that i was missing one of the bolts that fix the engine to the frame,
they put a new one and torqued it to the specs and the bike runs perfectly, neither i nor them had ever thought it would be something so simple.

Mission critical bolt! I'm happy they fixed it.
thanks, not sure how to record stuff and post it ( I'm what they call a bit of a Luddite here ) I did read somewhere that the PAIR valve opens up engine noise. Sounds a bit daft maybe but I think it might just be engine noise that somehow is amplified by the tank , it is quite loud with the helmet visor open. I have had several 4 cylinder bikes, 600 and 900 Yamaha Diversions, Suzuki 1200 Bandit, Honda CB1000FA but they didn't rattle like the cb650f.
I believe the engine cases are thinner nowadays to keep weight down which doesn't help with noise reduction.
What mods have you done? If I may ask
If you still have the PAIR valve in and working, yes, this bike for some reason had an ungodly loud PAIR valve that sounds like a can of bolts shaking at idle to around 3K rpms or so. It annoyed the hell out of me at first but I got used to it and wore ear plugs so it stopped being an issue.
Until I’d ride the bike again without ear plugs in or up the block to get gas without a helmet on, then I’d remember I wanted to block the PAIR system.
No idea why it’s so loud on this bike, but it is.

Thank God you've now got a Ducati instead. Ducati's never sounded like a box of loose screws
Engine crash bungs ,front fender extender, givi rear rack arms for top box baseplate , scottoiler V system chain oiler , that's about it , no modifications to engine , fuelling or exhaust system.
Well there is that. But earplugs work great on that noise, too!!!!Thank God you've now got a Ducati instead. Ducati's never sounded like a box of loose screws
I once heard a ducati describe thus:
Sounds like a skeleton having a wank in a biscuit tin.
For the USA guys:
Sounds like a Skelton jerking off in a cookie tin.
