Everyone in the 440 Micro class knows how hard it is to find 440 motors, what im proposing is that we run a 250cc liquid cooled motorcross motor as an alternate engine allong with the existing 440cc sled motors. One of the first years at Grand Bend Speedway they allowed a 250 cc car to run with the 440s. The 250cc motors are eadier to find, the are run in all shifter karts and the US micro sprint cars (they allow 270 cc max). They are cheeper to maintain and to buy, you only need to rebuild one cylinder and set up 1 carburator vs 2 of each in the 440. They have the transmission already included, thus more savings they are lighter allowing you to move more weight arround. The cars with 250cc engines can be push started , or using the kick start. These motors typically produce anywhere from 45 to 55 HP in stock settings and 60 to 70 HP with the same mods as the 440's. The 440's produce arround 50 HP stock and 70 HP with mods. In the 2008 season I will be fielding a car in that class, if approved I would run a 250cc engine in my car to prove that the car can be competitive and safe. The location of the rad is the other factor, placing it infront of the motor on the right side would be the ideal location. Anyways, give me your thoughts and ask around to see what others have to say!Ryan Desat
