Im looking at a 2002 YZ426F and a 2003 YZ450F. The 450F has the hot-start assembly on it "not too sure what that is". Which bike would you guys recommend? Pro's and con's of each? Im pretty new to the 4-stroke world. I rode smaller 4strokes when I was a kid and I had a couple of 2-strokes a few years ago. But these new 4-strokes might as well be from a different planet...I rode a 426F a while back and I remember how much of a pain it was to start, how bad it fouled plugs, had to fool around with the pressure release on the handle bars, and how heavy it was, but i've read a lot of people are yanking parts from the 450 and putting them on the 426 to fix the issue. I would assume that I just get a 450 because its lighter and people seem to really like it, but i could be wrong. I will eventually get back on the track, but i'll mainly be riding trails for a while till I get used to the new bike. Thanx for the help guys.
