hi recently become a proud owner of a tzr 125 1990 has a 2rh motor and a newer chassis but not the 4dl .I've ridden others before and one had the powervalve pinned .mine is not running  but will be soon .haven't tested the servo yet but was once told that it is possible to link the valve straight  to the throttle. just wanted to verify?

I have moved you to the workshop.

Say high in the new members area, otherwise you come across as one of the many one post wonders which we get an awful lot of, one question then never seen again.
