85 VF700f Reserve Tank full of crud

I found some house hold cleaning vinegar with 6% acid I'm going to try that

www.caswellplating.com "fuel tank sealer" It's an epoxy, and you're gonna find some pinholes you didn't know about when you acid-etch the tank. The sealer will easily block the pinholes. :witless:

 

Should I still put the vinegar in the tank because the instructions said it likes to stick to a rusty surface.

Do yourself buy a favor and either buy another tank, or a "kit". Check out one called Kreem, I think its called. They give you stuff to clean the tank, and then stuff to coat it. Also, it is sometimes cheaper to buy something than get it for free! Good luck

 

Sorry, GT, but the Kreem product is not as good as Por 15 or the Caswell epoxy. It's known for peeling off after a few years.

 

I have had very good luck using Metal Rescue and some nut and bolts. Use could use fuel or the vinegar as well. Put some in the tank with the nuts and bolts and start shaking it. It will give you a good workout, but it works pretty darned well. Make sure and count how many nuts and bolts you use and just pull them out with a magnet. Also, with the petcock valve off, you can use compressed air to clean out the hard lines on the tank.

 

That tank is bad...real bad. You better bang on the bottom all around with a rubber mallet hard enough to make sure you don't end up driving around with a bomb under your crotch.

 

You have everything you need, based on the pictures. Throw that bike on top of that stack of wood and burn it. Project complete.


OK, j/k. good luck with your resto.

 

A little extreme, don't you think?

 

Yeah but as of now and the more I tear it apart it's not going to happen because of the state it is in... It needs to much and it will never be worth a ton.

I'll throw in my $.02 here. My tank was pretty bad as well. I put a gallon of lacquer thinner in it and let it sit for a day, then I swished it around and braced it up so the liquid stayed in contact with a different area...repeated for a week or so, then rinsed everything out well. Another solution if you want it done correctly and safely, is to find a local radiator shop that services gas tanks. They will super clean the tank, then seal it. The only problem is, at least in my local shop, that they will not guarantee the paint will survive the process. If the tank is in good shape, get it clean first, then consider getting it sealed (they do not need to immerse the tank for the sealing process).

Great find, good luck with your build and make sure you keep us up to date. I just went through all four of my carbs, removed from the air cleaner bottom (not generally recommended) and managed to get everything back together and running perfectly. My bike was also a garage find and I am impressed with how well it came back to life. Also, somewhere on here is the link to the online FREE manuals. I now have three and between them, they cover everything. This: http://www.partzilla.com/parts/search/Honda/Motorcycle/1987/VFR700F2+A/parts.html is an excellent source for OEM parts, though sometimes expensive, and a great reference for seeing what parts are called which can sometimes come in handy.
