@@hugoparox Mine has a locked power valve shown at 0:05. I believe they used this to close the PV and restrict the top end power instead of a cdi restriction on the earlier UK models.
@@RHauto And yet it's still really fast, that's awsome. I wonder if that's a thing in the rest of eu as well. But is it a plate making it unable to turn more or is it specially made to be restricted?
@@hugoparox I read online that the UK dealerships installed them to comply with learner licence restrictions.. The biggest problem now is it lacks low end power when the PV is adjusted fully open, but I can live with it. Riding a DT with a working YPVS feels like a completely different bike, it surges forward faster off the line
I´m driving a 1997 4BL Model and it runs with stock engine and exhaust same speed... i would recommended everybody. It´s easy to upgrade to 25Hp or more with exhaust made from gianelli and membran made of carbon. Some other jets in the carborator and this maschine is a beast compare to other 125ccm models.
