I might have a manual that covers that, I had a DT 100 and a DT360 but older bikes. the 100 was a 77 and the 360 was 74 if I remember right. I would love another DT360, that bike was a blast. 2 stroke same as the DT 400 except a shorter stroke. I rode that bike on the highway and it kept up and passed traffic no problem and was a blast in the dirt too.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
