Honda-SOHC

Ethanol will saturate at about 4.5% water, then it can't take any more, and excess will separate and sink to the bottom of the tank.  Isopropanol on the other hand can take care of many times that.  So, if your bike is going to sit, dump in some Seafoam, which is naptha (a component of most fuel additives) and ~30% isopropanol.  Or you could use a couple ounces of isopropanol by itself.  The naptha is a slow-acting solvent, dissolves gummy deposits.

The problem with water occurs when you have a partial tank, and not in a stable temperature environment... i.e., the tank breathes as the air expands and contracts, drawing in new moisture.

I have the Hondaman on my CB350F...... just to add, you can (maybe should) leave the condensers disconnected, and if you ever broke down, reconnect them then.

Welcome, Rich.  I'm sure you'll become edumacated as you go.

Good day, everyone, I've been lurking for a while here and for quite a while on the US site.  Thought I'd better introduce myself.  75 years old, retired, and have been riding several bikes over the years, mostly modern sport tourers.  A couple of years ago, I purged my collection down to one sport tourer and at this stage of my "career" I thought I'd tackle a restoration project.  I always wanted a CB350F (or similar vintage Honda) for many years, and finally was able to pick up an affordable one.  I'm well on the way with it, with the help of forum members, and always soaking up information.

My avatar is a pic of the bike the day I brought it home.  It looks better there than it actually is, it needed cleanup and all the red bits need new paint.  I"m trying to keep it as original as possible, or at least the original look as possible.

In any event, happy to be here.
