I never knew for one they had a 426 till I came across it in my local cycle trader. So anyway whats the deal with them? What years did they produce them? Are they a pretty good mx bike? Do they feel more like a 250f or 450f. Are they slower then what the displacement tells? I found one for 1600 which seems really low and the guy said it needed carb adjustments Im going to call him tommorw to get more info but any help would the helpful. Thanks!
