[QUOTE="oexing, post: 125015, member: 1493"] Vincent, what do you mean "too much movement" with this Alton ESA ? I found this photo with pins working in poly bushes, so only minimal movement I´think, minimal "elastic shock absorption " then. In a Vincent twin I´d block the old ESA for fear of slamming the end plate due to wrong shape of lobes and useless springs in that case. But I suggested to leave out two or four springs and put lengths of 6 mm O-ring strips inside and suitable cuts of 6mm /1/4" rod on top. So the rubber strips can compress to a minimum via the 1/4 rod over them but prevent a hard bang onto the spring plate stop when you tried out a combination of o-ring plus steel rod by squeezing the assembly in a vice for checking it does not touch the end plate still. This would be an easy mod to try but so far nobody jumped at this for reports. Vic [ATTACH type="full"]36359[/ATTACH] [/QUOTE]

The Series 'A' Rapide was known as the '********' Nightmare?
