475cc STROKER kit for your YFZ450
for any of you yfz 450 owners that want more power, B & B Racing now has a 475cc stroker kit available.
depending on elevation and exhaust setup, this kit should net you between 55-60 hp to the wheels.and thats with stock cams and stock carb, put in some webcams and a FCR-MX 41mm carb and watch the rocket go then.
we will disassemble your motor,stroke the crank, bore and replate your cylinder, port and flow your head, put in our custom 12.8:1 compression piston. then reassemble with all new gaskets.
the torque increase you'll get will far exceed the hp gains. but it is torque that accelarates you not hp.
you ship us your motor, and in 6-8 weeks it will be shipped back complete ready to bolt in and go.of course you will need to rejet, and i will be able to give you jetting requirements at that time.
the entire package shipped back to you complete is $2025.
have any questions feel free to ask. just don't ask me what the dimensions are, those are a trade secret. and we don't wish for any of our competition to get ahold of them. we are the first and the best performance engine builders to offer a motor kit for the yfz. our kits are built for reliability and to kick ass.
and the motor will look bone stock from the outside so you'll never have to tell your friends what they just got smoked by.
