Title: Tank cracks
Post by: 3858 on May 10, 2013, 05:58:44 pm

Has anyone had luck repairing plastic tanks that have cracked.

I have heard of the problem but never seen it with a crack running right next to where the tanks sticker had been.

The bike in question  is  a Yz250 L...

A common problem on YZ's and IT's. Often the cracks don't go all the way through. mainly a problem when they get hot.
Can be welded with Poly Ethlyne rod, quite sucessful. Some people may even have the right colour rod.

I've had a couple of plastic Hodaka tanks welded up. In no time at all they split again down the side of the weld :'(. Darcy

My CR125 89 did the same, l used some Devcon, mixed it up and forced it into the crack and so far so good....

Thanks for all the advice.....over the weekend the tank seriously cracked about another six inches either side..... >:(

I think the re-introduction of the fuel to the tank pushed it over the edge...dang it....  Clarke tank now on the way...
