TOPIC: bad, bad gas

I had to trace down a bad wire connection after the rally in July, The gas has been in my tank with stabilizer for 3 months, not good. Can you tell the good from the bad?

New connection on the bike and the Boyer, all posts on the coils cleaned, re-set up the Boyer rotor, fresh gas, strobed it and it starts right up and runs real smooth.

I'm going to guess the one in the middle. On the subject of gas, I had a bad experience with ethanol eating away at my 72's fiberglass tank two years ago. I had Caswell-ed the tank about 10 or 12 years ago so I got my money's worth I guess.
The resulting industrial strength splooge got distributed throughout the engine and carbs, gumming everything up. Most serious was the wrist pin circlip that came out and gouged the cylinder wall about .060". Had to get another cylinder block that was still on the standard bore.

Ended up doing a full engine rebuild as a result, but it would have been needed at some point anyway as there was play in the rod bearings, worn cam followers (and they were mismatched by previous "mechanic" as I found out), and other miscellaneous bits. Thanks to Tony Lockwood for directing me to a crankshaft grinder in the Denver area who was 1/4 the price of some thieves where I live. Did a nice job too with the correct radius at the journal end.

So now with new rod bearings, pistons (.020" over) and rings, reground cam followers and a new steel gas tank I'm back in business and very pleased with the result.

Bottom line: I'm empathetic when it comes to bad gas!
