    Yamaha RD250, 350 & 400 owners please note: Installing these reed valves will require modification of the intake port of the cylinders. We suggest using a Reed spacer to move reed cage further back to allow space for intake machine work to fit the cages. setting them up against the cylinder intake. Can cause over porting damage breaking out the intake side walls when releaving the intakes to fit.

    you can also contact us to machine them for you if needed. 

     

    RD250/RD350/RD400 owners looking for more a bolt in application can try using our YZ85 reeds for stock reed cages. you can message us for details.
