[QUOTE="riptragle1953, post: 36276, member: 2328"] This is a sticky wicket with the Vin.... usually in the range of 45 to 55 is quite usable.... but as far as ideal or perfect.... that can depend on so many things, like an Egli frame for example. But, most vibration problems with a Vin have nothing to do with the balance at all.... the usual culprit is poorly fitted main bearings: a bearing is as only as good as it's housing and with these soft cases I always line bored and fitted aluminum bronze sleeves for dead true crank alignment and perfectly round bearings using a .0006" to .0008" radial clearance.
