Rust in the float bowls

[Piercems3]

When I drained out the float bowls to winterize the vmax this year I noticed a fair bit of rust coming out of the left rear float bowl. The other bowls had little or no rust fragments. I refilled the bowls about 4 times and drained, and continued to get a little bit out of the left rear float bowl.

Is there a filter between the tank and the carburetors? If so, how would rust be accumulating in the float? The bike is immaculate overall, but I have not inspected the inside of the tank. What is the best way to inspect it? It is buried pretty good down under the seat with a pretty small opening.

Any advice is welcome!

If you remove the seat, you can see into the tank with a flash light. There is a drain on the bottom, but most likely it's time to re-coat the inside. There is a filter on top of the tank, right side, but like all filters it's a compromise between filtered particle size and longevity as well as flow. It's never 100% effective. There should be threads here on the coating procedure, as many members have coated the inside of their tanks. I'd drain the carb bowls a few times after you address the tank. Do a rebuild maybe. I bought a small medical type, USB camera, on E-Bay for $20, a few years back and its come in handy many times working on my ride. I even got a view of the dreaded orange o-ring with some wiggling and twisting.

I'd suggest coating your tank.. I've done 4 tanks so far.. 1 for me, and 3 I've sold.. The system I've had great success with is the KBS Tank Sealing kit. It takes a bit of prep work, but once you're done, you'll be happy with the results.. KEY IMPORTANCE: Follow the recommended steps and make NO shortcuts.. Also note: Since it takes a few days to fully cure, take that time to remove and fully clean your fuel pump, lines, filter, and clean your carbs out. Afterwards, you'll be a happy camper and you engine will like it too. Hint: If you go this route, go to Home Depot or Lowe's and ask them for about 2 feet of old style window sash chain. The sharp edges of the links makes for excellent removal of surface rust, and you can pull it out easily when you're done.
