Hello, Firstly, I have never owned a Commando before this one so I'm not sure what they are supposed to vibrate like.
I have another topic about "strange vibration" refering to an intermitant vibration at 3800 rpm and over.
Anyway, I tried adjusting the isolastic mounts looser and the head steady also looser to see what that does.
Now with the isos looser the whole bike vibrates up to 3000 rpm then smooths out, (but the strange vibration is still there at 3800 and over)
Should a Mk3 vibrate heavily throughout the whole bike with the isolastics and head steady loosened?
From what I've read here it should smooth out about 2500 rpm.
If I tighten everything and and back the isolastics off a bit as per the instructions the normal engine vibration disapears at 2000 rpm and is smooth through out the rev range. (strange vibe is still there intermitantly)
Why does this bike vibrate worse with the isos loosened?
I can move the back wheel about 3/8 ths of an inch with the isolastics loosened, to give some idea of how loose they are.
Graeme.
