getting dents and rust out of xj650 maxim gas tank?

Ive got a 82 xj650 maxim and the gas tank is dented in 2 spots and is rusted inside so i was wondering if anyone knew how i could get the dents out and get the rust out?
and if anyone is selling a xj650 gas tank around metro Detroit please send me info.

oh and I'm new to bikes and cars, 16 years old and i live in southeast michigan.

 

Welcome, I'm new from the Metro Detroit area as well. I haven't done too much to my project bike, but I have cleaned out the tank. I used phosphoric acid based cleaners and a foot long piece of chain. People have different theories on how to tackle this issue. Here's one thread about it...if you don't see anything you like here, use the search option! http://xjbikes.com/Forums/viewtopic/t=2 ... horic.html

 

thank you that might work what about getting dents out, anyone?

 

i just did a honda tank with electrolysis it worked really good

 

i have the same bike/same problem

is it smarter to buy a new tank or to clean it out?

 

It never hurts to try and rehab the one you have first Inspect your tank most tanks will be the worst where your left thigh will be when your on the bike thats where the water will accumulate when the bike is on the side stand chances are if the paint has little bubbles in it there its rust from the inside and if you poke at it you will spring a leak the tank can still be cleaned and sealed but if thats not your bag then buy one and get out and ride

 

If I remember right, I used the POR kit for motorcycle tanks. Some people complain that this coating comes off after a while and makes things worse, but I have a very strong suspicion that they don't follow the directions. It gives very specific instructions and you have to follow them EXACTLY, otherwise you won't get a good bond and it will begin to fail. But mine seems just fine and I think it's been like 5 or 6 years.

That's one option. But I don't really think you should try to rehab a tank if it actually has holes in it. Mine was structurally fine.

 

i was wondering if i could cust the dented area out and weld in a homemade patch panel has anyone done anything like this to a gas tank before then use one of those great ideas to get rid of the rust?

and theres no holes and all the rust is in the inside.

 

or would filling the tanmk with pressured air then caping it off then use a suction plunger to pull the dent out
