I think it is caused by your pipes coming strait out the back, I would put some turbo like chrome pipes on and point them down and a few degrees out . I have that on my rampside and do not have that problem however the vans have much different air turbulance

How come 62 carburetors on a 65 engine?
The flapper vent and high speed enrichment on 65 carbs are good things. 53 jets are rich around here, even on 64 and older carbs.
I'm speaking to the way this thread has progressed without knowing what your deposits are.
Normally there is only visible condensation until the exhaust system warms up, although who knows with the corn squeezings and such these days.
I wonder how you will attach tube socks to your chrome mufflers without melting something onto the chrome.
As an aside, you say hotter plugs. How hot and why?
I wonder if the highway speeds prevalence is strictly aerodynamic in nature?

I had later carbs on originally, but I couldn’t get them to run the way I wanted, so I used what I had around, and they seem to work much better.

I bought 4 new for my later carbs, to bump up a touch for the modern gas. In case I screwed a couple up, I had spares...and figured why not when I decided to use the early carbs.

Duct tape? I’m not too worried about getting the melted tape off..

> As an aside, you say hotter plugs. How hot and why?

No, colder. 2 or 3 ranges on NGK plugs. I had pinging issues that I tried to cure with colder plugs. I finally figures out it was caused by my later carbs. Go figure. I just haven’t changed the plugs back.

You got me.

Thanks for taking the time to help me. I appreciate it!

Before I do something I can never unsee (socks on exhaust), I’m going outside to check on the cold plugs, and see what they look like.

well,
I took the easy way out. I installed an old exhaust system I had laying around. No spots after a 20 minute highway trip.

So it was just water/soot from normal combustion.

So you are running a B9HS? That is really cold. If you can get away with them not fouling they are fine. Colder plugs won't change what come out your tail pipe. They just foul easier. The heat range is what keeps them clean.
Air cooled street bikes used to use 7s so 9 is 2 steps colder that that.

Joel, I wrote a correction after I pulled out the plugs. Originally I thought I had gone colder than that..drinking smiley
But while I’ve got you on the phone, does the plug look OK, or should I go back to the preferred plug of b6hs?

I prepondering that your on to something. The stock single exhaust can retain heat more than the duel's with Harley mufflers.
I'm willing to bet the stock system holds and burns off exhaust moisture, condensation better than the duel's that evacuate exhaust so fast.

But I was really looking forward to seeing those sox blowing in the wind!grinning smiley
