1969 DT1 Restoration : was created by Quartermaster35

I purchased this Yamaha from forum member Yamahaha last week in North Carolina.

I brought it down to the Charleston area where I reside and began the process

My plan is not to bring it to perfection but to get it close and just make it reliable for Sunday afternoon rides.

And so it begins:

- Soaking parts in vinegar to remove the rust

- Primer Coat on a few parts

- JB Weld on small hole in exhaust......... (will need to sand it down of course)

Whoa! Just needs one of everything! You'll get to know her pretty well by the time you're done. Sure looks like a DT1 from here. Post up picks as you go and there have been a lot of good tips for resto on this site.

Here's tip number one.
There's nothing wrong with vinegar i have used that and electrolysis many times .
The problem is when you remove the parts . They rust before your eyes.
I recently got introduced to Evaporust .
It's recyclable ,very gentle ,removes paint to a good degree and is okay on your hands face clothes etc.
It doesn't give off any vapour and you don't reek of pickled onions for days on end either.
It's not the cheapest product but by heck it's good stuff.
Great to see you tackling a bike that's just been left to rot.
Regards Ted.

Thanks Ted....... I should have posted here first as I experienced exactly what you stated with the rust appearing immediately. :)


Do you recommend using Evaporust for stripping down the frame?

It can be done, but it's a bit of a faff and you lose some of the Evaporust.

According to the company's instructions, you need to soak a material in Evaporust (I used Gr8auntiepat's paper kitchen towels! :EEEK :ROFLOL ) and then wrap this around the areas that need de-rusting. Not as good as being able to soak a part in it for 24 hours, though.

Evaporust isn't designed for pulling paint off .It's rust ,but if you immerse an item long enough it removes the paint totally. Id imagine you would need a paddling pools worth to do that frame my old cock Sparrow.
Probably some form of USA paint stripper would be better, then paint it with Phospharic acid and water solution . Or Jenolite which is a Phospharic acid suspended in a paste solution. Turns rust black and stabilizes it.
I have a picture of a tool box that looks like it came from the bottom of the Gulf of Mexico. 3 days in Evaporust and Bosh,it's clean as a whistle. No paint nor nowt . Now it looks likw the surface of the moon but that's another story.
