I've been reading for a couple months now and still haven't figured out the motive for this. Why would someone buy the WR and do all the mods (Cam, grey wire, etc..) to get it up to par with a YZ? Seems like you could just buy a YZ and throw the lights\heavier flywheel on it and it would be cheaper than doing what people are doing. I personally bought the WR for trail riding and didnt want an MX bike. Is that not the general thinking for buying it? I realize a lot of guys do trail ride with all these mods, but that brings me back to why didnt they just buy a YZ to begin with..buy a YZ and a heavier flywheel\light kit and save your cash. Please don't flame, I'm just trying to understand what the thinking is.
