Could anyone tell me how much hp a std 85-86 gsxr750 put out???

 

[oldgixxer]

Cycle magazine's dyno from back in the day said 79 at the rear wheel for the 750,and 89 for the 1100.

before I did the motorwork I had it dynoed at 85rwhp with just the Hindle pipe for modifications. It may have been around 80 or 82 stock.

I acn not believe that none of you gave the right response to this question... The correct should have been "not enough, you need more HP."

It was at 115 before I crashed it.

Well i picked up the bike tonite after work and steve (the dyno man) was as happy as shit

mate! hows 101 rwhp sound to you (he said ) the first run we had 91 and rich as can be and now you have 101 and its a good strong motor so on the trailer it went go it home put the tank & tail on took it out for a ride and wow

Nice, even pulled my first power wheelie

going for another ride tomorrow.

thanks again for the imfo now i need to find out whats been done to the motor.

A standard motor with 36mm CVs and an aftermarket pipe should give nigh on 100 bhp. With a well-ported head (note I said 'well-ported', as a poorly ported head will do nothing), you should get significantly more than 100 bhp. 101 is not significantly more than 100... Have a word with the bloke who ported the head, and tell him to get a different job...
