If wheelies are your thing and you've done them before, you'll have no problem doing it on the FJR. It's not my thing, but, I have inadvertantly lofted the front once or twice. I swiftly pulled over and gave myself a slap on the wrist. 1st gear from a rolling start, get 'er above 2500 rpm and grab a handfull of throttle (and cover the rear brake pedal). Don't know about clutched wheelies...never tried 'em. 2nd and 3rd gear wheelies over hill crests are simple, too. Wouldn't dream of doing stoppies with that much weight.
Just read some of your other posts and see that you might be on one of the european hp-restricted models. If so, disregard the above.
