I'm a newbie to the Savage and am waiting on my jet kit to arrive.  Is the jetting different for ethenol vs straight / real fuel?

Which makes me wonder?  Our bike was designed in an era when fuel did not have any ethanol content.  We have become accustomed to making jet changes to get the mixture a little better so the bike runs correctly....no big deal.

It may be that the TEV ciircuit could actually be suffering a bit from the use of ethanol fuels.  The TEV (Throttle Enrichement Valve) is supposed to add some additional fuel when you are operating at a high vacuum (deceleration or between gear shifts when the throttle is suddenly closed) - when you do this the high engine vacuum pulls a lot of air past the slide and throttle plate - but the only fuel circuit that is open is the idle circuit.  This idle circuit cannot supply enough fuel to make a combustible mixture in the cylinder....so the spark plug cannot ignite it, and when it goes into the hot exhaust system it is ignited.  The TEV circuit is supposed to add enough extra fuel to keep the mixture rich enough to burn in the cylinder - but in some cases it does not.....so folks start putting bigger jets in to correct this issue.  Unfortunately the bigger jets are not good for economy or power, and it wastes fuel.

I wonder if the TEV circuit worked well with gasoline......but is not sufficient to work with ethanol laced E10?  Is there some way we can increase the jet sizes in the TEV?  Cutting the spring only makes the TEV work sooner or more often....I don't believe it increases flow once the valve is opened.

Who wants to look at a carb and see what the TEV circuit uses to control flow volume?  I don't have a stock carb anymore....so don't have anything to look at.

Funny story about ethanol:
When my wife and I were acourtin' she had a 50 Suzuki step through, and her brother was racing go karts. He wanted to go to the store to get parts for his bike, but there was no gas in hers so he put fuel in it (ethanol+klotz+nitro), did his errands, and parked it without telling her.
She came home from school and set out to pick me up from work, where I took over the driving. I noticed it wouldn't idle very well so took to revving it a bit at stoplights. At one light it ran itself up to max rpm. I turned off the key and it kept screaming away. I yanked the plug wire (with my bare hand, giving myself a helluva jolt and possibly causing the congestive heart condition I have today) and it kept screaming away. I pushed it into a gas station where someone pulled the plug and it quit.
All it needed to fix it was a bore, piston and rings, and a new head, because the "mechanic" cross threaded the plug when he re-installed it.
That was an amazing little bike. My wife and I flogged it severely- riding it 2-up on the highway, not worrying about how much gas and oil it was going to use, but how many spark plugs it would take to get us there. When it needed it's third bore and there wasn't enough cylinder wall left, we retired it.
