Trophyn vibes

Just thought I'd run this past you,my 94 Trophy triple is fine solo ,but two up and i get heavy vibrations.
Chain tension seems fine (I suspected it might be tight) but it still vibes when we are free wheeling.
Next thought was a plug breaking down under load? Any ideas appreciated (and my pillion is only 10 stone )
Merry Christmas by the way! :cool:

Thanks both of you.
Dave im not thinking it might be wheelbearings because it seems to ease if I freewheel with the clutch in.
.
I need to sort it though as the tension will put strain on the bearings.

when you powering on the chain pulls onto the wheel bearings, power off and load removed. You might be using enough power to get what performance you want and be using more power when two up, plus the chain will be tighter due tolowered suspension.
It used to be a technique with triumphs to keep power on when cornering. this enabled the chain to act like the string of abow and keep the swing arm stable to stop the bike weaving. problem was you ended up going faster and faster on long bends :)
