My new project, plan to use everything I learned from this terrific group! My new project, plan to use everything I learned from this terrific group!

You are now officially an Enduroholic.

A great starting point. Look like it is mostly all there. What's the mileage?

8500 miles
kicks over with a very substantial compression bump
tank without dents, cap on tight so haven't gotten a peek inside
only thing missing that I see is air filter cover and tool kit
gonna power wash it up, take off head to check it out, clean carb and validate jet sizes, check pump output after flushing (still oil in tank so hopefully nice), get spark and get it started. 
want to get it titled and Reg for original '71 plates. 
 

I'd try and see if it'll start with fresh gas!

I love the way you think!
will try and see if I get lucky!
no key - does unplugging ignition switch unground primary side of coil?

Found an extra 30 mins this am
But for a pint of very stinky brown gas the tank is clean!
diconnected black wire coming out of main switch and got strong spark!
going to drain carb and lube and free up throttle and then hook up mini $10 Amazon tank and hopefully start her up tonight 

thanks all I will do until title search comes back un-hot!

what's best chem to clean out stink from tank?

thank you
 

Check the VIN the color of the tanks and headlight look like a 70DT1C

I pulled up your handy dandy VIN table when inspecting
came up as DT1F-35983, which I thought ties back to '71...but it was dark and my eyes aren't so hot

Yes just unplugging the switch will let it run. But if your old fuel is anything like our crap pump gas in NZ since we went unleaded then it's likely the carb jets will be gummed up. Can't come to much harm draining carb & trying it first the so long as throttle is operating freely & good idea to have an escape route if the throttle sticks open to be able to kill the spark--like a kill switch just tapped into the coil primary. Early DT's had a black short wire with a female cover coming off the black out of the mag loom--that black runs the motor so the short black is easy to get at as will be unused & easy to hook to. Love the old DT1's.
