Dick,
I think the large breather tank on top of the crankcase (actually the oil tank at the point) wax a bit of strangeness that the previous UK importers developed.
The reason I came up with the old-style decompressor mod was for easier starting with a custom built AVL/classic Bullet hybrid motor, as there was no E/S. However when killing the compression to stop the engine it means that it won't "bounce back" against compression, and in the case of an E/S bike, and try and drive the sprag clutch backwards. This is a milder version of what happens if the engine backfires, but is still best avoided. If you CAN get your valve lifter to work properly (I share your dislike of it, but some owners recommend using an old style handlebar decompressor lever instead of the feak and weeble plastic lever in the l/h switchgear) or do the decomp. valve modification, that might prolong your sprag clutch life. My Electra's sprag survived for 9 years despite some 'orrible clanks and graunches. None of this will make your big-end last any longer, though!
