Also, make sure the 2 rings go in the proper place. The scraper ring and
the compression ring look alike. But the ring with the little tooth goes
in the middle groove, and the other on the top groove. They both say
"top" on them for orientation. And be careful, they are brittle and I
snapped one of the damn things and had to buy another set of rings
because they only come in sets.

I'm going to be installing a Nikasil (850 replacement, not
big bore) kit in my '74 Eldo this winter, and I'm thinking
I should go ahead and get the whole "top-end done". The
bikes mileage is unknown, but I'm guessing between 50-75k.
Nothing leaks. Some oil blow by.

So far I've been doing a rolling rebuild on this bike.
I've had the motor out to diagnose a tranny problem,
repaired and reshimmed the tranny, and fixed up most of
the externals;, controls, cables, brakes, carbs, and
existing wiring, did the alternator conversion, and
removed the heads to check the chrome on piston tops (they
were fine, but I want to do the Nikasil's anyway). I
don't have machine tools, so I'm prepared to draw the DIY
line there.

This is all new territory for me, but I'm surmising I can
probably install the cylinders/pistons myself, but should
probably have the heads done (new valves, guides, etc.?)
by a qualified machinist that knows loopframes. I live in
Southern MD (western shore). Does anyone have a
recommendation that's close by, or maybe I should just
ship them out to Mark E., or is this work I can do myself?

I'm sure its not a straight answer, but opinions welcome.

Thanks, -tom
