Sorry to post another "what's faster thread" guys, but I just bought a clean 400f, and this is my first of the performance type four strokes I've had. I am very impressed with the amount of power and the hook up this bike has. Twenty years or so ago I had a pig of a bike, a 1982 YZ 490, and was wondering if anyone has ridden with someone that had one, and how do they compare on power. Obviously the 490 has more ponies but loses most of them in wheel spin. Can the 400 hold it's own with it's tractionable power delivery. Just kind of wondering as its been SO long ago on the 490.
