Update:
The worst part was the smell coming out of the tank, which was really bad, I believe there was a lot of varnish that had collected in the tank.
The household vinegar did eat some of the rust. But it was really slow, and not enough.
I swapped to electrolysis.
Which is working to get the rust out.
So far I have swapped the water and chemicals twice and cleaned the steel anode a lot more than that. I am using very low AMPS though so its taking way longer than it should be.
I have rebuilt and cleaned the Carburetor and used a rebuild kit.
The good news is the outside of the carb is clean, the bike has 5K miles and my brother owned it since new and garage kept it.
When I opened the bowl there was a black tar like substance on the float, the bottom of both jets, and the bottom of the bowl.
Anyone that has seen this before?
Sprayed the float with carb cleaner black stain came right off... Soaked bowl, A/F screw, idle and main jet in carb cleaner overnight and it dissolved/came off.
I wire brushed the outside of the jets and it shined them up.
Large jet was open, and all holes were clear, small jet had blockage in the main hole.
There was nothing I could get through that was small enough and hard enough to pass all the way through, blew air through it and it does flow through, but I am not overall happy with the main hole cleanliness. Carb cleaner went through under the spray can pressure with no problem, I might remove the bowl again and take another wack at the idle jet.
The carb is back on the bike but trying to get the rear most carb heat hose on really sucked, any pro-tip on getting that sucker to seat with it wrapped on the backside of the rear intake, like it was when I removed it?
I have wrapped the bike in Vinyl... so it is no longer red but yellow, added the highway bar, and a windshield and fairing, and lower fairings, still working on the lower fairings, they are made for a Harley, and were a might wide for the bars I purchased.
FYI I have found that the parts and pieces of the VTX are not fun pieces to learn to wrap on.
Have not done the tank yet as I am waiting until I am happy with the inside state before removing the badging and the doing the wrap.
So after slicing a few inches off the inside of the lower fairings, and removing a few inches from the closing vents I was placing the right side on and dry-fitting and its really close to the front exhaust cover, so I am going to do some filler and add a layer of heat shield to protect the ABS from melting from proximity with the exhaust pipe.
I have replaced all of the lights headlight, brake light, and turn signals with LED's.
I also replaced the turn signal relay with a low amp version to avoid hyper-flash.
I have not yet installed and wired the USB plugs and the battery tender, nor installed the new battery.
Once I get the tank rust free, and coated, then cleaned and vinyl wrapped I will remount and then fire it up, hopefully!
I will take it to the local shop and have them mount and balance the new tires and do the state inspection.
