My latest bike. This one deserves a nice restoration. Hope I am up to it. Most of the parts are there, the rest are not that tough to find. Engine is stuck. So is the tranny. Fork tubes are probably a total loss, maybe the rear rim as well. Fuel, oil tanks have zero dents. No dents in the rear fender and pipe either. Just lots of corrosion.

Going to be fun!

I had the (green) 100cc MX version back in the day and my grandpa had the enduro version of the same bike. Ah, the memories....

Looks like fun.

I have worked on a later model before at work. They are pretty fun bikes once you get it going.

Dude, that bike is awesome! I saw a rebuild/conversion of that bike to short track, it was absolutely amazing.

I'm gonna search for the rebuild and then i'll share with you!

My intention is to make it look as Yamaha intended. I have never done a show bike before but am hoping I will be up to the task. Here are a few shots of a '73 360 I cleaned up a couple years back:

Starting point. Pretty complete bike:

Taking it down:

After powder coat:

Fork cleanup:

New top end and other engine clean up:

Assembly:

Finished. There is no better bike for running errands around town or just cruising down a twisty country road with an occasional dirt road thrown in for fun:

I am expecting the DT1 to be a much bigger job and I have give it much more attention to detail to really make it right. I think its a good starting point, will know for sure when I get it opened up.

Damn

Great job with the one

Thanks for the nice comment. That one was a far easier job and is also a rider -- not intended to be a full restoration. The DT hopefully will be.

I couldn't help but notice from one of the pictures the two spark plugs, whats up with that?

citabjockey · « **Reply #10 on:** January 25, 2012, 03:25:23 PM »

Yamaha made a few models that had 2 plug holes. You could either carry a spare plug or install a compression release. The problem with that head on my DT1 is its not original. don't know if I am going to do anything about it. Others that know more than I are hinting that it may be a high compression model...

Its possible. So does the second plug actually spark and help fire off, or does it just sit there in the cylinder head and do nothing?

It does nothing -- that is until the primary plug fouls. Then you move the spark cap to the spare and ride away.

That is actually pretty handy. I would keep it on there, it looks interesting and it serves a purpose, kind of...

My '71 Bultaco uses both plugs. If you change the ignition, you can have them both fire. Had a Husky that way once too. My '73 Husky now has both holes but since it has a Motoplat (vice points) one plug is a spare.
