Y.S. 140-160DZ
I never really cared to much for the Y.S. 1.40 DZ's idle charecteristics and transition, but it made some serious power and when it was right it was pretty awesome. Now take that motor add approx. 500 R.P.M smooth out the mid-range and idle and you have the 1.60. I am really pleased with the way this engine runs in all aspects, its like the 1.40 FZ was 5 years ago. If you are looking for a good powerful and reliable combo., its going to be hard to beat. I have been told they are currently making a production run of these engines so they should be hear within the next month or two.
