hey guys, i just acquired a 69 honda trail 90. its in decent shape and i plan on stripping it down and restoring it. im thinking of doing a olive drab paint job with a flat back accents. maybe put an old army star on the sides and make it look old school. anyone else have one? |

Quoted: I have my Grandpa's old '70 trail 90 that I want to restore too. I just don't have the time, space, or money right now. Post pics! -Mark. i will when i get it all done. i just tore it all apart tonight and its going to get sandblasted and painted tomorrow. damn should have taken a before pic.... |

Well, to start with, a restoration is not olive drab with stars! Go back original, or let someone else have it! Those old Hondas are worth some big bucks these days. I started a Trail 70 project that was a basket case, threw in the towel and sold it. In the middle of a '66 Mustang GT fastback "Resto Mod" I didn't need another resto project.
Oh, careful with the sandblasting. I have seen blasters warp sheetmetal from the heat it generates. Just do the hard parts, frame, etc... |

I owned one for 15 years. It was a tough little bugger. Finally broke the trans when the chain came off and jammed into the sprocket, cracking the case and shearing off the trans gear teeth.
It would go about 45MPH on level ground. And about 60 downhill. Got about 80 miles to the gallon and could hold 2 people fairly well with a square seat on the back. I loved it and would have another, if I could find a cheap one. |

I loved it and would have another, if I could find a cheap one. i was cleaning the motor up today and noticed what looked to be a hole in the case above the sprocket. i took the side cover off and sure as shit there was a hole in the main case right above the sprocket. you can see where the chain had been thrown at one point and caused that hole. im thinking thats where all the oil was leaking out of it over the years. not sure how im going to fix that one! |

How big is the hole? Thinking welding or Quicksteel? This look similar? I'm with trucking AR - original. When you're done - name her, get to London, get a milk crate and off To Sydney, Eh! You can one up Nathan the other way if you hurry. Sydney to London on a Moped called Dot |
here are some pics of the cracked housing. oil seems to be coming from the hole just below the electrical connection. im not sure what that electrical connection is for (one with green wire) but im sure that it doesnt need oil and i could close that hole and have no problems.     |

A careful JB weld might do. However, your best bet is to have it welded.
The suggestion above for a new engine may be good, however, the Honda Trail 90 engine (in good condition) is way better than the Chinese copies. They generally take the 50-70cc engines and put big bore kits in them. In other words, the engine is not the same platform, similar, but not the same. Plus they don't have the OEM HI/LO range transmission. |

Quoted: The wire is connected to the neutral switch. The area in the pic needs to be oil tight. Have a GOOD welder fab an aluminum 'patch' and file it down to fit the sidecover so it will not leak. does what switch need oil? what i was thinking was to close that oil hole that is below the switch and call it good. oil just trickles out of it, nothing too serious since its up on top. |

The hole is a passage for crankcase mist that lubes the left side of the shift drum stopper bolt. Best not to block it. JB weld might work if you can get everything spotless, and make sure it seals to the top of the sideceover. |
