Quite a happy co incidence you finding Cliff. I love his videos and his voice is easy on the ear ....well that is until you mention Brexit and then the air gets a bit blue lol.
He'll be chuffed to bits to know that you were sufficiently inspired by his vids to get your bike out and start restoring it.
Poor old Cliff rides a lot in built up areas which have speed cameras everywhere so he is restricted to 30-40mph which I would find very frustrating. I can only charge around like a hooligan because there are no Police out where I live and very few cameras .
Interestingly enough my bike has almost no vibration !.... I can't feel any through either the pegs or the bars. I feel sure that a lot of this is due to having the engine running efficiently with regards timing and fuel mixture but the high rise bars with rubber bushes must help a lot as well as not having my weight on the bars. Saying that I have never ridden further than 30 miles in one go so thats no real test I guess.
