Hey Menno al ok???

Is it a big hole or just a smale crack??
If its not to big you can meld it with a soldering iron an fil it with a zipty.

Advanced auto sells a plastic gas tank repair epoxy. It works very well I've used it on a couple tanks . It is very runny though so be careful.

Is it a coating for inside the tank??

Maybe this could work than Menno!

No it's a 2 part black epoxy that goes on the outside. Like I said it is very runny at first but sets up very fast. To prep the tank all you have to do is clean the area with sand paper.

I've never seen any type of glue or epoxy that stuck to a plastic gas tank for very long. Not even the stuff that they claim is for it. The best luck I have had for repairing tanks is with plastic welding. I like to use an old fender, you can cut it into strips to be used as filler rod. Then you have the right color and the right plastic to make the repair. The down fall is that plastic welding is an art just like any other type of welding. When I do a tank repair with heat I like to fill it half way with water so if I want to cool the repair I can just role the tank over.

I too have used the plastic gas tank epoxy from an auto parts store with great results.  Mine was the clear, not the black.

thanks BDI

i tried to plastic weld ,found out the whole bottom was cracked,while prepairing..
so i,m stuck with buying the sec-hand tank ,
just because i,m very afraid the tank will crack wide open.
with me sitting on it while doin a 70 mph straight ,
i don, t wanna think of it,a gallon of racegas sprayed over the very hot pipe & me legs

If the tank has cracked like that it's probably brittle from age. Sounds like it has hit the end of it's life cycle to me.

I had a melted hole in a CR250 tank, from the exhaust being too close.  I simply drilled a round hole at the leak , welded a flat washer to a carriage bolt, put a rubber washer on the bolt and fed it into the tank with a extendable magnet. Then on the outside I placed a rubber washer, then a flat washer, then a nut, I used a cutoff wheel to trim off the protruding threads. I did apply locktite first. This repair never, ever, leaked and as far as I know, the bike is still being used this way. Maybe next time, I would try a chrome washer and chrome acorn nut on the outside.

Does Clarke make a tank for the K5? I was looking at their tanks and noticed they make a range for quite a few years of bikes.  Also try justgastanks.com.  Cam.

[turtle22]

yes clarke's does. a 4 gallion for under$200(&two other styles,also). its on the websit u mentioned

[BDI]

I do think they offer a stock replacement tank for the kx500. There has been a lot of kx500 tanks go tits up over the years so I think they started producing them.

it,s not brittle yet ,but it is wear on the edges of it ,s bottom ,
making it thin and then easy to crack.as it did..

Maybe it was already an aftermarket tank menno.
Is it realy grey or light black??? Kawa makes black tank fur sure.
And for the clarktank I've E-mailed them but have no anwser yet.
Wanted to know if there is a euro or even benelux dealer for them, for a bigger than on my AF.
In Holland there more into aluminium tanks, but they cost to much!!!!?700,- and up.
