High speed vibrations

[Fazerjon]

Hi yes mildly tuned, full Monty Ivan’s kit fitted by Mike, MotoGP slip on end can, Pipercross filter and that’s about it. It’s been fine for years, I balance carbs yearly and she pulls through to the redline cleanly in every gear. At around 105-110mph the vibration starts. If you keep the throttle pinned you can ride through most of it. It also has 2002 R1 USD fork conversion but easily hit 160 before with no vibes. I’m veering towards the Michelin Road 5 tyres now as there’s not much else left to check. Bit annoying as they’re bloody new tyres!
