Got a 76' cr125m with a pin hole in the bottom of the gas tank. Leaking fuel. Any suggestions in how to fix this would be appreciated. Thanks in advance! |

I have not done it, but I spoke to my dad just this past weekend about another bike tank that I have that is all rusted out and he said that some of the radiator shops have an epoxy or something like that that they will "swish" around in the tank and it is suppose to re-seal it and be a good fix. I don't know if it is an epoxy or what they use. Not sure how true this is, but it wouldn't hurt to ask a shop or two to see if they could point you in the right direction. |

Call around to your local radiator shops & see if they can weld aluminum. (I'm assuming your tank is aluminum) Most radiator shops are able to pressurize & submerge a tank to locate a leak by the trail of bubbles then weld it up. You could also coat the interior of the tank with "Kreem". Be aware that modern gas can break down some of the Kreem type of linings, so make sure that you find one formulated for todays fuels. Kreem can usually be found at most Bike shops or online. Eastwood also offers a tank sealer type product. http://www.motorcycle-superstore.com/1/ ... Liner.aspx Please let us know what you find out. I have a tank that leaks also. I just haven't had the time to pursue the remedy yet. Good luck ~JM~ |

I have sealed a few steel 75 CR125 tanks with POR-15 Motorcycle Fuel Tank Repair Kit and been very happy with the results. You must follow the directions very carefully though. I don't recommend "Kreem". Mark |

The 125 tank should be steel. Which is why this problem develops. Rarely see it on the aluminum 250 tanks. How does the inside of the tank look?? If it caused by rust and corrosion, probably needs to be cleaned and sealed as others advised. If it is a puncture, I've had good luck with solder repair. |

Defo dont use Kreeem... use POR15 or KBS. do a google search on both products and you'll see the results of Kreem, its scary and takes a long time to remove im told. ![]() |
