Speaking of which, my LAT-70A wheels have some stains on them that I would like
to get off - anyone with suggestions on how best to clean these without
damaging 'em? What are they made of?
I sent a post a couple weeks ago about my speedometer clocked all the way at
the high end even while standing still after being shipped to MOMA three times.
Some suggested that the problem was at the transmission gears, and others that
the O-ring was compressed and the hub was pushing on the glass face.
Well, I finally got around to pulling it today, and once I got it out, all of
these shiny brass filings showed up everywhere between the face and the glass.
I pulled the entire sucker apart - the O-ring looked fine, and it didn't look
like anything was too tight. I didn't pull apart at the transmission end, as I
can't see how that would effect me since the odometer works correctly. Using
compressed air, I blew our the brass filings from the innards and looked for
damage, which I couldn't find. I installed the innards and face only, set the
pointer to zero for the first time in a long time, and headed out. It
immediately jumped clockwise around to the post and hung there. Took the
pointer off, and the hub pin just spins nicely unimpeded by any speedometer
control mechanism.
I'll be calling Margaret at MOMA on Monday, but I think this speedo is a lemon.
They've been really nice about "fixing" it for free the past two times, but
I've lost hope that they will ever fix it correctly. It's the *only* thing on
the Tiger not perfect (except an occasional back-fire on rapid deceleration),
and it's really starting to get to me.
Anybody out there with a working speedo for sale?

As my elbow grease is low, I have cleaned aluminum wheels with
sulfuric acid (plain old battry acid, available at auto parts stores).
This acid does a good job of cleaning rough aluminum castings.
DO NOT use Hydrocloric acid ( ie pool acid) This will turn the aluminum
black. If you use acid , do it outside with a fan blowing on to assist
in removing the fumes. Rubber gloves and disposable clothing are also handy.
Be sure you have a hose ready to flush the acid off the wheels, and any where
you splashed acid on your self.
After the acid bath you can then proceed with the elbow grease.
If someone is considering acid to clean their alternator, take
care. The alternator housing apparently has zinc or something in it
and the acid may cause the bearing holes to etch out too big.
