Evaporust is weird as I hear some getting great results quickly while others report week or more to get good results. The chelation process used by Evaporust, Metal rescue Oxalic Acid and others likes heat and it does take time. I wonder if fuel varnish is causing it to be slowed?

Congrats on the ride and enjoyment

You are on it Dave about the fuel varnish effecting the results and time.

We rinse the tank with acetone to clean out the fuel residue and dry before the EvapoRust.
EvapoRust lasts a lot longer when you clean oil/grease off first.

+1 on cleaning any varnish & residue out of the tank. It won't touch anything but rust.
I've had good results with evaporust but it can be slow on heavier rust. Keeping it warm and agitation helps.

I ordered some Gen-U-Wine Keihin jets for my CL350K3 today.
Probably should have done it months ago.
Having some issues with the carbs and the existing brass came from who knows where.
Do you have a copy of the Honda Shop Manual or Parts List for your bike? Get one here:

Well after several days of Evaporust in the tank it cleaned it much better than last time. I drained the Evaporust out and flushed the tank with boiling water and a little detergent then after draining it again used my heat gun to dry it out.

Being that it was 100 degrees yesterday the tank got very hot very quickly so no obvious flash rusting. Sprayed Inox lubricant (like WD40, only better) into the inside of the tank, and this morning it still looks good. When the rain stops I’ll flush it again with some oily petrol before fitting it to the bike and filling it with fresh fuel, and it should be good. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Got the carbs installed and the air box attached to it on the 1100F after many frustrating hours. New throttle cables too. Next job is painting the exhaust headers.

We've learned on the 82' CB 900F that when assembling the airbox everything has to be at just the right angle including the carbs for it all to go together nicely. Seems like it's just as finicky as the CB 550 and soon we'll have to get started on the 83' CB 1100F. ::)

Cliff, I cannot see how you would be rejected for the vintage plates given your attention to detail and refreshing the finish on everything that needs attention. I think they would be hard pressed to find fault with your work and think it anything less than more than acceptable.
Best of luck with the exhaust touch ups repaint...
