Acquired another Enduro today. The photos on craigslist showed a black tank, and it looks like it was built for hill climbing or stump pulling. I traveled to Portland (125 miles each way) hoping it was an RT-1, but it ended up being an early DT1B according to the serial number. (DT1 15624)  Has not run in years but the engine turns over and the wheels roll. It has some interesting parts on it including the front fender, the expansion chamber, and the seat.The expansion chamber tucks into the frame and comes out behind the seat. The front fender is a little different then I have seen before, but was probably common back in the day. The seat is also different then I have seen before, but looks after market.  Would love some feedback from all of you.1969 DT1B, 1971 DT1E, 1946 Chief,  1949 Scout,   1949 Arrow,  1979 FXS ,  1999 1200S,  2002 Scout,  2006 Crazy Horse 124 Chief .

Look forward to pics when posting is back on track. Sounds an interesting DT1.

I really want to see pictures of this thing mainly the expansion chamber tucking into the frame. I just built an expansion chamber out of some sheet metal i had laying around with a pie cut header but dont really like where the chamber routes. I was thinking about routing it under the seat but went the easy route and just put it where the old exhaust went. Now that i know that i can do the pie cuts without too much effort and i actually refilled my bottle of argon so i dont need to use MIG, i'd like to give a under the seat route another go and make another.

There are still photos up on Portland Or. craigslist.

found it i think

YES thats it,
