Mirror ((( shake )))
Anyone got any top tips for reducing mirror shake? Riding today on my first observed IAM ride and the one thing that became quickly obvious (when I missed a turn as I couldn't see my observer indicating behind me) is that my mirrors are sometimes shaking too much on rougher roads to see the observer and their signals behind me unless they're right on my tail. Important as when I do the test at some point in the future half the ride will be taking signals from behind and I could fail on observations if I miss one.
I'm imagining anything to weight the ends to stop vibration will actually add to the wobble. Any tips / solutions / miracles greatly appreciated. |

Fairing or bar mount, standard or aftermarket?

Re: Mirror ((( shake )))
I don't recall the mirrors on my K6S shaking so much that I couldn't see behind, but then again I wasn't doing observed rides either ...
The only thing I can think is, are the two main fairing mounting bolts just in front of the steering head properly tight? Shortly after buying my K6, I realised that a rattle / clonk from the front end was because those two bolts had worked a little loose. Quickly fixed. |

Re: Mirror ((( shake )))
Do you have intercom?
Does your observer? Will the examiner? But don't tell the observer why though you could ask him why it vibrates.

Re: Mirror ((( shake )))
One of the main causes of Mirrors vibrating is the Carbs/Fuel bodies out-of-sync.One of the best investments I ever made was buying a Morgan,"Carbtune2" balancer,
https://www.carbtune.com/index.html https://www.carbtune.com/carbcust.html It's now around 15 years old and still like new.Fantastic quality and serviceable. I suffer from VWF(Vibration White Finger) so am very sensitive to vibrations through the bars.My 1999 Curvy has as close to zero vibrations as possible. If I didn't have a super smooth Motorcycle it would be hard for me to ride any distance but I also have heavy bar-end weights just in case.Bar end weights don't really reduce vibrations too much but can shift them to a rev band where they are not an annoyance. If you watch this video of me going over the Humber Bridge you can see how little my mirrors vibrate, Properly balanced Fuel bodies also mean the engine and throttle response are superb as they should be.

Re: Mirror ((( shake )))
Cheers.
The vibration is not constant though, only when riding rough road and going over bumps, so I don't think it's anything to do with the engine. Any synchronisation needs to be done by a dealer on the K8 too as it needs their special tools to lock the fuel injection. Observer and examiner won't use intercoms.

Perhaps a trip to a trusted Mech or the dealer? My MOT guy is cool and will use his rolling road/brake tester to diagnose things usually for free and check them for his customers.

Re: Mirror ((( shake )))
Can you fiddle with your suspension/tyre pressures? It may limit how much vibration is being transmitted through to them? Maybe see if loosening your grip helps.
We use comms for the most part but also do runs without as sometimes they fail so it's worth making sure you can. Have you explained the issue to your obs? They should be understanding as it's about safety not trying to spot an indicator in your mirror. Failing that, when junctions are coming up try and sus how far away you are when they start to signal, then at least you can get an extra check in and hopefully catch it. Don't forget, your examiner is not going to try and catch you out, when you put in for your test and speak to them, explain your issues, they may surprise you. Ste |
