Another plug for Seafoam

Post by tunaboy » Fri May 10, 2013 8:07 am

I have been taking plug readings for a week or so and found that I had a plugged pilot jet in # 3. The spark plug was coming out sooty the last 2-3 times. I ran 2 tanks of gas/Seafoam through the bike and I just pulled the plugs again and now they all look nice and lightly tanned. The bike starts, runs and idles well. This all with a bench tune before the carbs were re-installed. I can't believe how well the bike runs with just a bench sync. I am not sure if I want to look at the sync with my mercury gauges or not, riding is more fun than wrenching. The bike is an '80 1100 and the pilot jets have been lightly seated and backed out 2 turns. I know that the manual says 1.25 turns but 2 turns seem good. This bike is one of the early 55mph bikes that is geared lower. I am pulling 4K @ 60 mph and about 4600 @ 70 mph. I think the 82's and 83's spin about 4K @ 70mph. Downshifting is not necessary for passing with this gearing but must admit if I had a choice I would take the higher gearing for more sedate cruising and drop to 4th if I needed to pass in a hurry. Still the '80 is one nice scooter.

I would like to run something trough my carbs because I´m not going to take them of until next fall.

Best to all

Diacetone Alcohol 10%
Xylene 60%

Techron Concentrate
Distillates, hydrotreated light < 50 %weight Aka: Paint thinner(oil based)
Stoddard solvent < 35 %weight Aka: dry clean solvent, white solvent
Solvent naphtha, light aromatic 5 - 10 %weight : zippo lighter fluid
Benzene, 1,2,4-trimethyl- 95-63-6 1 - 5 %weight : powerful toxic solvent
Xylene , powerful solvent

Trade secret or proprietary formula < 1 ( secret #1)
Petroleum distillate(s) (unspecified) 40-70 ( most likely paint thinner)
Detergent/Inhibitor mixture 1-10 ( secret #2 )
Isopropanol 30-50 (rubbing alcohol, GAS DRYER "CH3CHOHCH3")

Seafoam ingredients:
1 PALE OIL 4229 40-60% = A base or process oil refined until its color = yellow.
2 NAPHTHA 20 25-35%
3 IPA 125 10-20% = Isopropyl Alcohol (rubbing alcohol),

"GM TEC" ingredients:
2-BUTOXYETHANOL, a paint and ink solvent , used even in Clorox cleaner 409
Naptha, , raises octane rating of gas, , simular to Zippo ligher fluid. Coleman camp fuel.
4-METHYL-2-PENTANOL, (aka:Methyl isobutyl carbinol) used as a lacquer paint tinner
9-OCTADECENDIC ACID.(aka:Oleic acid, found in Olive oil)

Light Aromatic Solvent Naphtha , ( Zippo lighter fluid)
1, 2, 4-Trimethylbenzene , commonly found in up to 7% by volume already in Gasoline.
Xylene ,(1,2-dimethylbenzene & 1,3-dimethylbenzene & 1,4-dimethylbenzene), xylol , powerful solvent
Cumene ,(isopropylbenzene, ) powerful solvent,raises octane of gasoline.

2-Propanone 30-60 % aka: Acetone
Ethylbenzene >10 % a powerful solvent
Hydrotreated Heavy Paraffinic Distillate 1-10 % weak solvent
Methanol 1-4% , solvent.
Propane 10-30% , gas
Toluene 15-45% ,powerful solvent
Xylene (mixed isomers) 5-20%

Red Line SI-1
1-5% Alkenylamine - (a detergent ,even used sometimes,in baby shampoo)
1-10% Isoctanol - ( C8H18O , aka, 2-ethylhexan-1-ol, or Octyl alcohol)
1-10% 1,2,4 Trimethylbenzene , (C9H12 )
5-20% Aliphatic Napthta , zippo lighter fluid. , aka: white gas, low octane)

Valvoline Complete Fuel System Cleaner
52 - 62% Kersosene
28-38% Light hydrotreated petroleum distillate
6-16% Stoddard Solvent ( stoddard is the name of the man who invented dry cleaning)

Army Regulation 70–12

Greetings Gunnar, glad to see a fellow Goldwinger in Iceland. I spent some time there back in the 90's out at the NATO base before they closed it. I sure would have loved to ride my 'wing over there, but they wouldn't let me bring it. Anyway, here is a great web link on how to make your own Seafoam using common products like diesel fuel, iso-heet gas line drier and Naphtha (or camping fuel like white gas). Check out the link, good information there.
