YPVS Controller Modification - An extra exhaust curve for TZ250L.

I've been working on some YPVS controllers for Pete(GB), Gavin(GB) and LES(CA) and I just found out a new exhaust valve curve that I want to share.

Pete owns a Tz250H converted to an L (electronic power valve). I have a few TZ250 (mostly reverse twins) exhaust valve curves on the blog but the below one is new to me.



Paul's Nsr250 Mc21

Many thanks to Paul(USA) for the photos of his Nsr250 and his kind words about the Battery Eliminator.

I purchased your battery eliminator for my NSR250 and it works great. Bike starts easily every time. Thanks, Paul
