Well it looks like I discovered the oil leak. My oil tank is seeping at the seams. Probably futile but is there a way to seal these? |

Nothing lost by trying, plastic welder, or a good old soldering iron. Melt and add material . |

Our opaque tanks are all PVC plastic, the black ones are ABS. Common hardware store plumbing cement works, PCV for PVC, ABS for ABS. Now, anybody have a different bike with injection molded covers, tail section, fairing, they are all,ABS. Use regular fiberglass cloth and ABS cement, stronger than new. My Yamaha RZ500 has a few places on side covers with mounting tabs glued back in place. |

Ok Thanks Guys. I'll try the ABS cement and a patch. |

I would have thought they were all polyethylene. I'm pretty sure my translucent '72 tank is. If your black one is ABS, you can smear a little cement on it, let it dry, and see if it's extremely stuck, or if it peels off. Edit: I put some PVC cement on one of my translucent '72 tanks and it didn't stick... I can peel it off in one piece. |

What I posted always works, never had a problem, but, what Jim said, try it first to confirm. I've had great luck using the fiberglass cloth and the cements, it always makes a strong bond and has insane strength. (Ronald Reagan), "Trust, But, Verify". |

Well, the first attempt was a failure. The ABS/fiberglass mat peeled right off during the test. I am going to attempt again after cleaning. I used acetone to clean but perhaps just soap and water? |

My '73 and 74 both have MDPE which takes a very special cement. Oil impregnated crack interface will not bond well. If I were me!!??? I would try a spot heat gun or iron, to chase the crack closed. cliff 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR40, Clear all of these glues need surface deactivation via. flame/ ozone/ or special activator. Probably not very strong on butt joints esp. with oil weighing on the sides and hitting bumps... Wonder how it split? |

The plaque plastic wouldn't be ABS, it would be PVC. |
