High-ethanol fuel conversion?

[eldevigo]

Howdy folks, I've got a notion in my head currently that's got me curious about the possibility of running my '83 1100E to run on high-ethanol fuels, E85, E98, or even E100!

I'm aware that some significant rejetting is normally involved in this, and also that E100 frequently has ignition problems on a cold engine and often needs a little help to get the engine kicked over on account of how cool it runs.

I know Ethanol is felt by many to be the devil incarnate, but I figure if I'm planning to run a high-ethanol fuel mix I will just have to get used to making sure i'm religiously cycling fuel through so it doesn't get goopy and wet.

I'm wondering though, have any other forum members done a high-ethanol conversion on a liter GS? Any tips or tricks to share?

One thing I'm wondering, for example, is whether running E98/E100 makes it possible for the 1100 engine to run with advanced timing without suffering its usual famous issues that normally happen on gasoline. I understand that in many other vehicles, the very high octane rating of ethanol (119 for E100, apparently?) frequently makes it possible to advance substantially more without issue.

I've called the S.P.C.M. (Society for the Prevention of Cruelty to Motorcycles). Expect a visit soon. :bull_head:

Maybe the drag racing guys have some tips on running straight ethyl.

Everything I've heard about pure ethanol is that if your engine can be set up properly for it, it runs cleaner and cooler, is more resistant to knock, and produces more power per stroke on account of it comes with oxygen pre-installed. Also, we can make it right here in my town, instead of having to get it shipped in from Saudi Arabia

Anyway, nothing I'm doing is gonna be worse than what the PO did to this poor beast.
