[QUOTE="Bill Thomas, post: 115526, member: 485"] Dave , You are better at Maths than me, What is the balance factor as it is now ?. I think most Vincent's have a bit of vibration somewhere, Maybe just get it nearer than what it is now ?. That is why Big Sid told me about lead weights in the handle bars. I am told I am wrong, But I think the higher the compression pistons the more they vibrate. I have used 12 to 1, On the track and because it was a road bike, Used it on the road also, I remember a younger racer asking me if his very fast Twin race bike should vibrate like that !, When running it in the paddock, I said Yes it is fine. For you I would maybe add compression plates, To get it down to near 7 to 1, I run 9 to 1 because I still like the punch when giving it one !, I have a newer type piston for my new bike I am building, But in my head I am thinking I should use one of my old type Specialloid's, Lots to think about. You have helped me with mine. Cheers Bill. [/QUOTE]
