I opted for the YZ instead of the WR because my bro's WR's didn't have the snap I like, and because of the weight. So, now I have to mod for my style of riding. I'm adding a flywheel weight, and fooling with the gearing. What's the general concensus on the "Power Now" stuff? And, any suggestions on trail gearing? I've got the stock 49/14, and man, does it suck! Also- one more- jetting for 5000 to 7000 feet?
