F2 was rated at 63 bhp by Yamaha, 31K models were 59. Bear in mind that these figures are 'at the crank'. On a dyno, you're more likely to see anywhere between 45 and 50 or low 50's for a good one  |

My Mito fitted with a 31k engine gave 53.5hp at the rear wheel on the Dyno if that's any help to you . It's running Mircon GP pipes and pod airfilters ( no room for an airbox ).

Dyno 'brand/type' used to produce those HP is a BIG factor.
Eddy brake type dynos give dramatically lower HP numbers than those printed out by the Long proven to be poor; Dyno -jet contraptions.

As bare says . different make of dyno give deferent BHP readings . you may get 58 and your mate may get 63 but in realety yours has more power its down to the machine being used and how its set up .
