Hey guys Im trying to fix multiple cracks on an 02 m2 tail Ive tried epoxy with no long term luck. Ive seen this issue bought up before but never heard of a successful solution from anyone fixing it, has anyone found a long term fix yet? |

I forgot to add most these cracks are near the rear mounting bolts so I dont have to worry about cosmetics there, I could reinforce but I'm not sure how to bond to the plastic or what kind of plastic it is. There is also a crack on the forward portion where it tucks under the gas tank, you cant see it when installed but I don't think there is any room for extra material. |

I've had those same rear bolt hole cracks for 25k miles. They haven't changed a bit, so I stopped worrying about it. |

Id love to ignore it but it has become worse and now where its cracking toward the front it will soon become a cosmetic problem, once it cracks the seat shakes so much when idling it seams its getting worse im surprised yours has not. |

Im thinking about trying a pvc primer then epoxy thinking maybe the primer will help get a bite onto the plastic, also this bike came with 7year warranty Im thinking about inquiring into it although Im guessing theyll just laugh at me. |

I use toilet washers (no joke - rubber coated fabric) to "isolate" the body part from the frame. That won't help you in the front, though. I did ask about the warranty, and they did laugh, explaining that body parts aren't covered, but it can't hurt to ask again anyway. |

i had a neighbor that repaired plastic bumpers on the side and he used this two part glue that the second part was a spray to activate it. it's been a long time since i've seen the guy but it seems that the bumpers are close to being the same kind of material as what the tail section is. i've got a cracked tail section also but aren't to worried about it either right now. |

well I decided to try a 2 part epoxy made for plastics, I dont know how different it is than other epoxys but this one is specifically for plastic so well see if its any better. Im also contemplating putting some rubber above or below to try to isolate it, and coating the inside with a membrane of some sort to try to help but havnt decided yet |

I used a combination of JB Weld and some thin metal angle iron on my original section and it seems to be working well. On the other hand I have purchased 3 tail sections (each for less then $50) 2 tanks, 3 wind screens, and two front fenders. I plan on having my bike for a long time abd would like to do one custom paint job. One of the tail sections committed suicide at a track day last summer. see pics here |

Freeflyer I have those same cracks on my 96S1 and they haven't changed much in the last four years. Good luck on the repair. Joe |

I have the typical vertical cracks across the tail just where the sub-frame ends on my '99 M2. To repair it, I removed the tail, gently pried open the crack and squeezed in a few drops of a plastic solvent to melt the plastic a little and let it mush back together a bit. Then, I applied two (separate) horizontal layers of carbon fiber (across the cracks) held in by two-part epoxy resin. The carbon fiber pieces are pretty large and strong, yet thin enough that they don't interfere w/ the fit of the tail to the frame. They go about 6" past the crack (forward and rear), and goes from the bottom edge of the tail, up into the channel that the sub-frame runs in. My logic was to cover a large enough to give extra support and transfer the vibration away from the weak point. All of the supplies were readily available at Tap Plastics. There has been no increase in the size of the cracks since the repair. |
