My 75 DT400b is definately more peppy than my 73 RT3 360 enduro but not by a whole lot. The 360 is definately more rider friendly as far as the power band goes. The DT400 prefers a lot of thottle or none at all. The 360 you can actually hold a steady rpm for cruising a lot easier. These bikes are so old nowadays that it's hard to get 2 perfect stock running examples to get an accurate comparison!

That's interesting what your saying about the 400, mine rode just like that, loved throttle but hated cruising.
Amazing how you forget how these old machines actually rode 

I have the same bikes (well 76 400) and totally agree with what you said. Man the 400 is peppy!
(Can't move my reply out of the quote...sorry)

There's a new behavior sometimes with quotes...  I fixed yours above...  see this post for how to do it.
