Default weird vibration

Went our last Saturday with my 09 fxd, noticed in 6th gear around 65to70mph with steady throttle or accelerating the bike has a vibration I haven't noticed before. Let off the throttle and all is well.

No problems in any other gear only 6th. Any idea's?

Keep it in 5th past 70 it may work itself out with a little time.65 to 70 is a bit slow for 6th IMO.

I'll throw a leg over it asap and see how it all plays out. I'm thinking of ordering the vibra front mount and finding a nicer rear mount to stiffen it up so it doesn't feel so sloppy at 80+ or he'll whats the since in having that 6th gear.

l wouldn't get too stressed about it, l've operated a lot of different machinery and if l stopped every time l felt a different vibration or heard a different noise, l'd never get anywhere or get any work done. l tend to take the same attitude to my bike, they're a pretty tough, durable machine.

as said, keep it in 5th until you're cruising 70mph or faster.

I have a Vibratechnics mount, and a 68t rear pulley and I think that makes cruising in 6th between 65-70 bearable but still more work for the engine than 5th gear so you'll burn less fuel using 5th.

changing your mounts won't take away your problem, it may do nothing but make the problem worse and that goes for the gearing as well, it's a crapshoot.

Mine does the same thing but in lower speeds from time to time. Once I hit 65+ runs smooth as butter.

70+ in 5th is wild. I have to shift right over 60 or it feels like I'm pushing it too hard. Then again I kinda baby my bike lol.

I guess man. Tried it yesterday and felt like I'd be living in regret instead of on the edge so shifted as normal.
