Ok a couple of weeks ago I fired my '82 R100RT up in the rain. It started normally but I noticed what I thought was steam come off the front of the engine (I now realize it was smoke). The bike ran fine and I rode it for about 15 min. About 30 minutes later I started it back up and it ran rough that got progressively worse then died and would not restart. After sitting a few hours it ran for about 5 minutes before dying. I checked the gas for water and it was clean.
I did some searching and found references to the diode board. I pulled it out and had it checked. The electronics gurus at work said it checked out (as far as they could tell). I did notice a lot of oxidation on the contacts and cleaned them.
Put everything back together (including the front cover which in hindsight was a bad idea). It fired up just fine for 90 seconds at which point white smoke poured out of the front cover and the engine died.
I'm about to the limit of my knowledge. It turns over, and has good spark. The way I understand it the diode board is only part of the charging circuit. I'm thinking the Ignition trigger unit since it is in the same location as the diode board, but would like to get some other opinions before I tore into it again.
