Hello Vincent . A question . Is your vibration mostly felt in the bars or in the foot rests ? If in the bars you might try some lead shot for a distance in each bar end , not tightly packed . Must be loose enough to move about . A change in bars might do the trick by being out of phase with the internal vibes .
I did earlier mention that Videan uses 60 percent in all Vincent motors and every type of chassis . Cycle world Editor Peter Eagan described our Vincati as being " liquid smooth " , no vibration felt , after his 100 miles on it . Further said it felt like being " flung up the road by the hand of God " when he rolled on a fist full . Very impressed with it . And it is built at 60 percent .
After Matt's first time ride on it , the first , I asked him what did it feel like , was it smooth ? He answered quietly this way . " once it's up to a reasonable speed it HAS NO VIBRATION , NONE in tank or bars , a very little felt in the footrests . Feels like being inside sitting on the sofa ". I was stunned . This is a fact , everyone who tries it says words to that effect . As did Jay Leno who had it up above 90 on city streets ! His impressions were captured on tape in the pace car trying to keep up , Matt in that car listening to every word Jay radioed back to the car .
Bill Jean built this motor . I set up the carburetion and timing , and also rearranged the ignition advance curve to slow down the rise in the advance curve , runs a D Dist , so this is done playing about with the flyweights and springs . As first fired up it was a wicked beast , wanting to fly , unpleasant in town running . I also swapped its Andrews Mk2 cams for a set of original Factory Mk 2 s .
In this way I tamed it's nature to be sweeter at lower speeds , til the advance kicks in hard , then it's hang on !
We also reduced its flywheel weight by a pound and a quarter . This explains it's spinning up so fast . Sid .
