" bacteria growing in it within a week due to the ethanol being a great thriving place for it."

You apparently don't know biology either. In "the real world" alcohol is actually used as an antiseptic (ie a compound which KILLS various microbes) From 12 year old bottles of scotch, to vodka, wine, and even that sterilizing cotton swab the doc uses before a shot, ethanol kills bugs dead.

Maybe you're thinking of diesel fuel or even gasoline - which can host notable bacterial colonies?

Have fun with it. So many people doing restorations go with upgrades. But yeah, if you are keeping it low RPM and low compression, there's no reason for FI.

The tax issue is with diesel fuel. All gas sold has the road taxes included, even if so.d at marinas. You can, if you are fueling your boat, collect the receipts and submit for a refund of the road taxes.

Marina fuel is usually more expensive because of the significantly higher costs of moving the fuel from the tank up on shore to the tank in the boat.

If there are any marinas around, you will likely find pure gas.

This is because ethanol in most forms bonds with water easily and will even pull water from the humidity in the air. This isn't good around lakes and with vehicles intended to be on bodies of water.

However, it will likely cost a premium to get. Probably because it is a niche market or perhaps the lack of an additive oxygenate in the fuel which ethanol is supposed to be (as a replacement for MTBE)

Though the knock resistance is higher because of the lower energy. So if you have a high compression engine that "requires" 91 or higher, and you have a choice of 87 "pure" or ~95 E85, you may see better mileage and performance from the "lower energy" E85.

Unless you are bumping the compression and using parts in your restoration good to 8k+ RPM, in which case FI is required for accuracy and volume (especially accuracy at high volume).

I restored a 75 CB550, had to do the same thing with mixed results. The biggest issue is higher exhaust temps, which I combat by adding top end oil. Works better than going richer on the jets and does not leave the carbon buildup richer jets leave on the piston.

You do know what fuel-drying solutions are made of, right???

Which is exactly what ethanol does...

but with motorcycles, ethanol has continually given Carbs troubles by promoting gas that gets all sorts of bacteria growing in it within a week due to the ethanol being a great thriving place for it.

I hate ethanol and it ruins motorcycles really quickly :(

2012 honda insight runs the e10 fine but gets better mileage using 0% ethanol gas from the local marina, ive had to rebuild the fuel system on my 65 datsun van because of the ethanol eating the hoses.
