Stealy fly wheel11/14/2022 ![]() I sold that RM250 in 05 to a friend who still has it & races it today & it & my 07 RM250 are 450 fast & both have very electric powerbands & very easy to ride. John & I are very good friends & I have sold a number of his bikes over the yrs for him. ![]() I know for a fact that John ran 16, 20 & 22 oz flywheel weights depending on the track. Both of our motors had the cylinders dramatically lowered to alter the port timing to give the bike way more bottom end & both of our engines had YZ250 pistons & YZ250 V-Forces with the carb spacer & both of our engines had 16oz flywheel weights. My 2007 RM250 was built by John Dowd's old mechanic & my motor was an exact copy of his last 2004 RM250 outdoor national set up. I couldn't disagree more with you about novices & enduro riders prefering flywheel weights & reed spacers to tame the hit down. ![]()
