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.
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..
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.
