$100 1969 AT1 Make it an MX Restoration #1
Here's the jumping off point.



I tore this down on this thread.

yamaha-enduros.com/index.php/forums/1968...t1-assessing-the-buy

It was a "let's see what $100 got me" thread. Since it's missing all street stuff, and sourcing all that stuff nowadays is becoming increasingly unproductive from a cost standpoint, it makes more sense to 1) give up and part it, or 2) make it an MX. Making it MX only clearly helps me from a cost perspective, and, I really don't have a true vintage Yamaha MX bike. Plus, it's a badge bike. And, I have an MX magneto setup for it already. It should be, relatively speaking, an inexpensive restoration. Right? Right??

Engine parts, nuts/bolts/screws awaiting sorting.



This shelf has the crank I'll use, for a magneto setup, not a starter/generator. The flywheel and mag are there, as well as some clutch parts that will replace the garbage that was in it.


Oil tank window is seeping the nastiness that was inside. Will have to be refinished and a new window, of course.

Typical way to tie up the headlight ears when the headlight was taken off, and put on a shelf in the garage in 1970. Then thrown away after the bike was long gone.



Look at all the crud that was UNDER those headlight ears though. Just a mess. Took the bolts out of the lower triple and drove a screwdriver in the slot to expand the clamp , tubes were able to slide right out even as hammered as they are.


And typical of all the rust on this bike...just look at the condition of the stem threads...

This is why you ALWAYS check brakes on bikes that sit. Linings totally delaminated, just sitting in the hub after pulling the brake plate.


Stripped down.


Of course the skid plate bottom bolts broke right off!! Quality time with my drill, sharp bits, and a 6X1.0 mm tap.

Already had to remove the back wheel, as it was seized when I drug the bike home. So removing the wheel this time was a peach. Stripping the rim and spokes was another matter. Tire bead was already split before levering off. 2 bead locks...I hate bead locks.

Can you believe how rusty this rim is??? Worst I have seen. This hoop is in the trash, I have another one. Hub is OK, but the wheel bearings are, of course, garbage. Will chronicle the front wheel this weekend. Swingarm bushings will also be pressed out to prepare for powdercoat, and will begin separating all the fasteners for plating. More to come.
