Time for a reality check and a cautionary tale.
My Longstoke project has been on the back burner for matter of years. The problem is the Camshaft. You see those followers? Well the cams are just as bad, it's a basic design fault with poor lubrication....the later design has a trough, into which the lobes dip, and although cams and followers on the later engine still wear, it is not to the same extent as this early version.
Brandis, as a new member to the Forum, you may not have heard the following fairytale.
With the increasing interest in old bikes, Wassell (the UK wholesalers for bike parts), bought up the rights to the Hepolite brand, from AE, the name we trusted way back. Modern Hepolite parts have no relation to the old company, only the name.
For many years A7 Longstroke Camshafts were unobtainable. Wassel commissioned new A7 and A10 Camshafts for their product portfolio. Now the later A7 engines share the same Camshaft, the A10 type, but by a twist of fate, the A7 Cams were made to the Longstroke spec. Folks ordering an A7 cam got just just that, Longstroke type, which does not fit the later engine.
So the UK retail market is full of high priced Longstroke A7 cams, and with a low demand...I'm waiting for the fire sale.
That central tappet guide is very similar to a pre unit Triumph type, but the genuine part turns up on ebay uk from time to time, with sellers ignorant of what it actually is.
Swarfy.
