looking to update up to a 250 two stroke from an 02 250f. Wondering about maintenance costs and performance characteristics of the two strokes. The honda is 10 lbs lighter than my 250f, I have read that the yz250 has the motor in stock form to beat. How abut jumping and handling, no complaints on the 250f, it has to be wound up to get the most out of it. Thanx for any info
