After many phone calls, wrenching, jetting, and paper work we finally have the results of the OEM cylinder shootout for the 250R.  This shootout started out to be a 12 cylinder shootout, but as time progressed, and builders either called or told us that they didn't have the time, or they just couldn't meet the deadline for entries. Therefore, when it was all said and done, we had 3 builders that stepped up to the plate, FTZ, APX, and MP Racing.

First of all we are not going to be declaring a winner because in there own right each one of these motor builders can build you a fast engine if you give them specific details what you want out of your motor.  We just asked for one that would be competitive in 300 ft. And as the times dictate, they each went about it in a different way.  (Editors note: The note that was sent with the APX cylinder stated this cylinder was intended for MX racing as the stronger 100-200ft time's show). We did not use their complete motor packages as we didn't want to get into a package deal issue but wanted them to build something to compliment what the average owner already has for pipes, carbs and reeds.  For more details on the requirements please refer to the following article.

For more info on each of these cylinders please contact the following builders as each cylinder has its own unique characteristics such as the carbon impregnation done on the APX or the welded up intakes and Top Hat style piston that MP Racing runs.

Each one of these cylinders is very capable of winning. We spent all summer racing each one through out NY State and won with each one of them.
