I think I can see the problem, somebody's been using your bike to make tea!
Is that little baggy supposed to be there?
I'd be cleaning that with carb cleaner first.
As for the Frame/Tank, are you sure it's a deposit & not a coating from the factory?
If it is just gunk that's going to be tricky, but if you can make up a plate to bolt on with a pipe outlet & tap on it, I'd try some paint thinner in there as a solvent.
I wouldn't do that with the pump though.
The most economic & pleasurable solution is to put it all back together & go ride it with good gas to wash it out little by little.
We'll all be happy to confirm to your mrs that it's the only sensible solution.

Might try scooping out a quantity of the goo, and put small samples in cups and try various solvents to see what works. Something as simple as rubbing alcohol may be the solution. |

Back in the mid '80s, I bought a Honda CB360 from a motorcycle junk yard for my girl friend. It ran beautifully, and the junk yard owner told me that when he first got the bike, it would hardly run. He dumped all the old gas, put in a tank full of fresh Premium and a half bottle of Gumout. He said that he had to turn the idle screws in almost all the way to just keep the bike idling. He let it idle for about 10 minutes, when the idle suddenly went up to about 6,000 RPM. He backed the screws off until the bike would idle and run well. He sold the bike to me, and it had no trouble running right up to redline smoothly, and made good power (for a 360). I told the story to a friend who had a Yamaha Virago that was running very poorly, and he decided to try it. A few hours later, he called me up raving that his bike didn't run that well when he bought it new, and he was now a firm believer in Gumout.
Why not try it? If it works, you'll be a happy man, and your problem will be solved. If it doesn't work, you'll be out less than five bucks. |

I've seen that green sticky gunk on my lawnmower's carb's pickup tube w/strainer that is immersed in gas.
Lately about every other time I try to start the machine, I have to remove the gas tank and free up the check ball that gets stuck in the tube from something sticky.
Not sure what it is though; it's not from stale gas. Maybe it's due to the ethanol in gas nowadays reacting with the brass parts in the carb? Or maybe it's a result of what happens when I used to put the older non-ethanol compliant Stabil in its gas? I used that stuff a couple times years ago but don't now anymore. Lately I've been draining its gas tank after using it, so the sticky ball problem is somewhat minimized but it still occasionally happens.  |

I just peeked in here, I have had issues with an oily stuff running out of the fuel tank vent hose (just replaced it ) when the engine was hot. I have to wonder whats in the gas any more. |

This is looking up the frame spar from the fuel pump opening. The gray area is above the fuel level that was unhurt by the fuel breaking down.The yellowish/green coating is fuel varnish! Brak-Kleen does remove it,but it would take about two gallons to get up to the clean area of the tank. I will have to see if acetone will cut it......I can easily get a couple gallons of that and let it "soften" for a few days .....or what ever it takes............crap!

Zip,
First I will say; great photography.
I would suggest that if you have the time and patience, mix a batch of "real" gasoline (who knows what that is these days) and marine blend Sta-Bil and let it soak for a few days. Flush and repeat until you're satisfied (visually). Then ride a couple of tanks of Sta_Bil treated fuel through it.
I have nothing to do with the Sta-Bil but it works for me.

Well,acetone did not work at all.So I'm off to the chemical dept at Wal*Nards for some mouse milk to experiment with. Ordered a new pump from American Sport Bike. |

I've found that SeaFoam works better than Sta-Bil |

What about just using fresh gasoline?
That crap was dissolved in gasoline in the first place, right? |

Well dammit.....with the pump out of the frame....all that gunk dried out to a tough shellac! Brak-Kleen, that easily dissolved the gunk when it was still tacky,wouldn't touch it tonight... without "rubbing". Acetone also worked with rubbing...........where it didn't before on the dried gunk with just sloshing some on and wiping it off.Windex doesn't work. Gasoline didn't work.What worked the best was a Wet Wipe. Those contain SD Alcohol 40. Looks like I need to buy a couple of gallons of denature alcohol,dump it in and let it soak for a few days or weeks. I'm going to rig the old pump with a drain valve and tube so I can easily drain it out and not get it all over the swing arm and muffler. And as always, Al at American Sport Bike responded to my online order with a email and tracking number..... |
