ET: Engine (Twin) ESA Upgrade

[Vincent Brake]

Hardend and ready to do some final machining

All that engineering and computer calculation it makes you wonder how 6 tubes of 21st century plastic seem to work OK on the electric leg Comet

It doesn't........ The ones on a friends 600 Comet were useless, so I locked it up, the Conway's Honda clutches have a cush drive in them, so that's all it has now.

Guess if you potter a Coment with only 20 hp, it works fine.
Nothing to smooth out..

Does anyone know what Patrick used (if anything at all) on his Isle of Man Grey Flashes? I guess they were putting out comparable BHP figures to a standard Rapide.

[Peter Holmes]

Of course, I should have known.

 

[Trevor Lever]

Well that certainly had the desired effect!
Ciao T.

I say not much different to a chain -shockwise - when you got no original shock generator on the crank.
Also I see no need for worries on a Vincent with TWO chains on the bike, primary and secondary. So no real hard shocks on gears. Chains are told to be too soft for overhead cam drives, so there . . . . . Again, Guzzis and BMWs got not a single chain in their drive , all hard gears, just the known ESA in gearbox - and they don´t crunch their gears all the time - well, mostly. And their gears are a lot lighter than the heavy Vincent components. Has anybody ever seen pitted gears on a Vincent at less than half a million miles ?? Even after snapping a triplex chain - they do reportedly - nobody needs to scrap gears from this harsh incident.
