[QUOTE="Jez Nemeth, post: 158106, member: 3871"] I had an ESA sleeve welded into a bored hole in the pulley, thought the splines would fit purpose fine -but clearly not tight enough on the crank stub nut -hence the rotational chewing. Looked at it again, and can be cleaned up I think without replacing. Think a machined out splined pulley will cope fine with the extra force of this engine starting providing above is observed -Thanks Chris When running yesterday the homemade ESA seemed to work fine, but will check the feel against the solid one once I fettle that onto the crank splines. Good thing about the belt ESA is that it does fit neatly under the original cover, and there is elasticity there -but like most bike manufacturers with cushdrives, they're all at the outputting end of the drive train system, where the back wheel contacts the rigours of the world beyond the bike, not the start where the power delivery is...anyway, it's no further outboard than with a chain. and may do for now -jury still out on it. Going to road test this weekend, because can't think of a good enough reason not to, and the weather is due to be accommodating [/QUOTE]
