I went into the race shop w/83 hp, left w/89.

92 F2 w/vance & hines ss2r, jetted, K&N and a 94 motor.

A.

 

so did the hpnumbers change from 91 to 94?

 

my 93 f2 is stock and is quoted as 95bhp (UK). Not sure how true this is but it's pretty fast

 

All the reviews I've read for the 93 say something like 90.8 hp at the wheel, and a tad over 100 for crank.

I'd like to get mine dyno'd just to see what it's making.

 

It depends on the dyno ,and who did the carbs.

My racebike made 88.7 on pump gas,with a nice linear power delivery, before the motor started to die.Stock motor,Two Bros full system,paper air filter.This was done on a Dynojet 200i eddy-current dyno.Pulled like a truck.

If the dyno is the "standard black" type,it will read optimistic (high). Eddy current dynos are much more accurate.


Current motor makes 101 on the wheel,on pump gas

 

It depends very much on the dyno. While at the Dragon, I dynoed my bike at Wheelers Performance shop. My bike didnt make the power I thought it would/should!!!
See this thread:

So I had it dynoed again here in my Hometown, totally different dyno and it made 90.5hp/43.4ft/lb !!! Much better numbers!!!!

I know mines a F3 but it shows the difference in dyno's!!

 

My 1991 F2, K&N, dynojet kit, hindle pipe, +2 rear teeth with vortex sprocket 520 conversion, pulled 87 at the rear wheel.
