I'm picking up my 2011 yz450 (blue) tomorrow. I currently ride a 2001 yz426, so I can't wait to feel the difference. I only plan on putting an hour or so on it tomorrow, just to give it some break in. I'm picking it up and heading straight to Milestone. I sat on a few, and man is the suspension tight when new. My question is, do you set your sag on it when it is brand new, or do you ride a few laps and let it go through the motions first? I'm about 205 pounds, and the new ones barely move when I sit on them. So, I'm not sure if I should let it go through the motions a little bit first, or set the sag before I ride. I don't want six inches of sag once it loosens up. I've read plenty of the posts on these bikes, but am also interested in anything else that someone might recommend for the first ride. I'll check all of the bolts, chain, tires, oil, coolant, etc. I'll probably not take it too easy, but will give it a few easy laps, then let it cool off and recheck everything. Then, I'll ride it harder the second session out, and not baby it. Once I get it home, I'll replace the chain with a Regina ORN6, grease it up, change the oil and filter, change the coolant, and put new tires and radiator braces on it before I ride it again. I may raise the bars 5mm with washers, after reading some posts about the bar height with the stock bars. I also plan on getting the tuner and changing the tune before the second ride. Any other tips? It's been about 20 years since I had a new bike!
