I remember seeing a racing 250r motor built with a 400cc Pilot Cylinder. I am trying to find info on it and have searched the site but cant find anything on it.

any direction would be great

Thanks

FTZ is well known for these. I saw one about twelve years ago, and it was pretty wild.

nowdays its not really worth the trouble when bolt on cylinders are available that make even more power..

Cool! didnt even know they made bolt on cylinders, way easier. I am just trying to find the best route for my next 250r transplant. my 250r motor is fine but would like to start building another motor for when my r motor pukes!

great info, now just need to find LONG rods for the 250r.

Thanks
