Trying to make an 02' YZ-250F into a dual use bike (mild Moto & non-technical Trails). I plan to add a heavier flywheel (+ 10 or 12oz.?) and an added tooth (or two?) to the rear sprocket. Also a Power Now carb. unit. I still want to keep a lot of the throttle snap of the YZ, but get a little more traction. Also, I hope to be able to lower the idle a little. On the right track? What set-ups would you recommend?
