One thing I found that probably contributed to the problem was that the sealing washer in th e pressure cap of the coolant distribution bottle on top of the engine had perished and there were signs of some coolant loss there. Also, not enough to even top up the overflow bottle. I've inspected under the engine after shutting down and could find no signs of leakage on the inside of the lower cowling, so I still don't know where it is coming from. There is also the possibility of a few drips from any o f the lower coolant hoses, or their fittings into the heads.

Damn side cheaper than buying new bands.

The original Aero Designs band brakes were slightly larger and the tabs were slightly longer than found available today. The result is a less than ideal fit. I've looked many places but never found an ideal source for the band brakes (even though I still like using band brakes for the 582). Best, Mike McCann Pulsar 1 - 582.
