With everything original but restored what do you estimate one could go for?

I have seen them go between 5k and 8k

Wow, that's a good hunk of cash. Do they still make all the parts for them to?

No. That's why. the bike was historic in that it was the first vertical single air cooled two stroke in a light weight chassis that made good power, was reliable,  easy handling, had reasonable suspension. Oh, and it was not expensive. First bike that worked pretty good on trails and you could ride it on the road too. Everything before then lacked one or more of these characteristics. The basic layout of the bike is still in use today. Yamaha broke new ground with it.

This particular year had many parts that were changed in later models so these parts are even more rare. Check out the tach that is smaller than the speedo. One of those that someone finds stuffed into a box in an attic somewhere that is NOS alone would be worth well over $500. I think the dentless, 1 year only, exhaust pipe that came on mine would be worth more than I paid for the bike should I part it on ebay (which I will NOT do).

I see... Well it looks you have quite the "diamond on the ruff" with this expensive kind of project. Good luck with everything.

I'd have to disagree with your assessment of the DT250.The small bore Hodakas, Zundapps and Sachs of the era had better power to weight ratios, the German bikes handled better with better suspension and all of them were as tough as the Yamaha. I think what distinguished the Yamaha was the advertizing hype that surrounded the promotion of the bike, that broke new ground.I agree as well that the Yammi made a fine street bike.

If you look at Greeves Enduros that predated the Yamaha there are more then a few design similarities.

125 Sachs of the late 60's were actually quicker then the DT. ;D

Points taken and quite true. Perhaps it was the marketing (or the low price, non-intimidating dealers, easy parts availability) but whatever the reason the DT1 really struck a cord and tipped the balance for a pretty large public acceptance of these bikes. As so many of them were sold -- esp the follow on models -- there are a lot of nostalgia buyers out there now that want to recapture their childhood. Hence the demand for these bikes seen today.

The first DT's were very well made and much cheaper then the Euros. I personally really like the Ossa Pioneers from that era, they handled well and had reliable,torquey and fairly quick motors.

Engine on the operating table now. Exploration into its "shiftless" nature should begin this week.  Carb should be taking a swim soon too. Top of the piston says 71 on it, looks like its already 4th over. Oh well...




Zero dents in the oil tank! Draining the rest of the injector oil. Don't think I want to save this stuff...

Is 4 over the most you can go on this cylinder?

Not sure. Probably ok for the jug  but may be tough to find a piston and rings? That said the jug still has hone marks in it. Could be a new 4th over set would work just fine.

Do they at least make the re-production pistons or one that will fit for you? Or are you going to have to look at some used part-out bikes online?

Nice. So are you going to bore it over again, or is it in good enough condition to put a new piston and rings in and call it a day?
