[QUOTE="vince998, post: 36302, member: 261"] From what i can remember (the rebuilt was a good 7 years ago) the vibration was constant up to aroung 3500 rpm, and increased steadily (everything was new so we didn´t ring its neck). Vibration increased with throttle opening (ie full accelaration) Relatively smooth on a neutral throttle Mk 2 cams, 9:1 compression, Concentric Mk 2s (32mm) The explanation i got afterwards (from the egli expert) was it was all down to frame harmonics. (something to do with the rear subframe?) [/QUOTE]
