Hiya Allan.

I'm probably not going to PC. I am going to probably take the frame to
metal workers inc or professional coatings inc (I think those are the
names) for blasting and do the paint myself. The steering head races
came out easily for me using a small hand sledge and a pin punch. I put
the face of the pin punch on the lip of the race from the opposite end
of the neck and did a rap at each 90 degree compas point until it came
out, driving the race out from the inside. The idea is to not cock the
race doo much and just drift it out.

SO far as I understand you put rubber plugs in the threaded holes (all
of them) for the spraying and they remove them for curing.

I probably have a set of passenger pegs in one of my boxes. Cost you a
beer.

What do you mean by chip in the cylinder wall? Trust me on this, the
cylinders is not a place to go stingy. That's how I broke my bike. If
the chrome liner is going, don't mess around, just bite the bullet and
put nickasil units on. A new set of rings will just peel the old chrome
off like cake icing. Bad stuff. I thought I could get away with it for a
summer and it bit me. Lesson learned. Now I am going Nickasil as well as
having the replacement crank cleaned out. Haven't found a place to do
that yet. Then off to precision machine to balance the flywheel, rods,
pistons, wristpins and crank.

You can rechrome the tank, but that is pretty spendy. MG classics is the
only place I know that does that. I think the tanks are a lovely shape
and would lok just fine painted with thin black rubber knee pads in the
same shape as the original chrome panel.

All my stainless I got locally. Yeah it cost more, but I like rummaging
in the bins. Stone Way hardware is a fun place to dig up fasteners.
Watch the home plating kits, they tend to be pretty thin unless you let
it sit a loong time. And of course you discover the pinholes the first
time it rains.... If you find a badly rusted bit, don't toss it, I found
a cool recovery method. Doesn't replace the rusted away metal, but it
did turn my naaaasty crusty tail light mount into a usable item.

I'm up in Snohomish. Holler if you need a hand.

Who are you using for your frame? What type of powder coat? I just
finished stripping parts off mine yesterday. All but the head bearing
races. (which, unfortunately are in bad shape) Does anyone do anything
to protect the swing arm threads in the frame at the coaters? I need
the muffler/passenger peg tabs welded up on mine. Any one have a source
for decent passenger pegs? I suspect as this project goes on I will have
many questions....

And, yes, the motor is quite a heft.

I bought this ambo in 1989 and rode it year round, rain or shine, until
late 1998. Since then it has sat awaiting a major refit. She has
deserved it for a long time as a reward for being so good to me. No
serious problems (I
think) other than a chip out of a cylinder wall (ran for years that
way). Lots of cosmetic issues. I am looking for an unscraped left crash
bar, and front fender strut, maybe a really straight front fender. I am
trying to decide what to do with the tank, which has fairly bad chrome
and multiple dings under old bondo. I have two front ends and two
complete wheel and brake sets as well as multiple tool boxes and side
covers, etc and will have some parts to trade, donate, or sell after all
is sorted out in a month or so. I am eyeing home cad/zinc plating kits
and stainless hardware other than the usual valve and timing cover
hardware which was done stainless long ago. Any good online sources for
stainless and metric hardware?

thanks guys
