Thanks Chad,
Sounds like the DZ is the one for me... Are there any performance figures for the DZ...?
sounds like it may be even as powerful, or more so than the Saito 200 V-Twin???? It will probably come down to one of these two engines for me. The V-twin has that V-twin appeal and the sound would be special : ).
The plus's for the Y.S. are inverted installation reliability and no fuss setup and consistent starting, idle and operation...and power.
My FZ 91 is without doubt the most powerful and reliable four stroke engine I have owned.

The Saito 200 will have to be a very powerful motor for me to be swayed from the 140 DZ option.

Cheers
