1075cc, cleaned ports, stage 1 Yoshi cams, 29 mikuni smoothbores, Tingate exhaust plus minor tweaks in 1980 8 valve GS1000st equals 105hp at back wheel. Any HP figures that match (higher or lower don't care) Thanks
 
I'll try to get some from the dyno this weekend if I make it out there.
 
1981 Katana 1100 with 57k miles, completely stock including intake and exhaust with #95 main jets instead of the 112's that were supposed to be there for the Euro model 87.6 bhp @ rear wheel. As bought.

fetch.dll


Already have a 4-1 pipe waiting to go on, will jet accordingly. Thinking about stage 1 with drop-in K&N or stage 3 with pod filters. Estimated power about 95rwhp (I hope...).

(And I didn't count the peak in fourth.) :wink:
 
I got 92 rear wheel hp in 1995 when I had a Yosh 4-1 and stage 1 jetting with the cover removed from the airbox. I think it had 122.5 main jets. I have since put a Dynajet stage 3 and K&N pods with a V&H supersport 4-1 exhaust. I have adjustable cam gears to put in (this winter if time allows) and hopefully will get another reading when done.
 
83 GS1100E. 1166 Wiseco 10.25:1 pistons, Cam motion G3 (.345 lift) cams @106IN 108EX, Vance&Hines Supersport 4-1, Keihin 37.5 smoothbores, mild port work, K&N pods = 129 HP at rear wheel. Could get more if I wanted to squeeze it all into the top end I guess.
 
1199 wiseco pistons, 38 smoothbores, Hindle pipe, Dyna 2000 ignition and coils. This dyno was done with a bad clutch four years ago.

So you see, I have burnt my brain out and hopefully amused you all.

So what it is?

Fill in the blank BHP = _________

Thanks :)
 
It's either Butt Horsepower or Brake Horsepower. I think you calibrate Butt Horsepower on the Butt Dyno, but I'm not entirely sure.

Over and out - Buttman 8)
 
It is actually Break (Brake) Horse Power

But I prefer Big Hooning Power
 
1981 GS1100 stock except 1394 ccs and 25lbs boost = Big Honking Power about 236 VERY STREETABLE HORSEPOWER at the rear wheel
 
So if it is break or brake HP then which is it and what does that mean? Does anyone know? Or is this just one of those terms that everyone uses but makes no sence and no one really knows why? There are things like that. I am hoping this isn't one of them :)
 
Brake horse power is actual horse power delivered by the engine to the shaft. It is equal to the indicated horsepower less the fiction of the engine also call at the crank horse power
 
Or brake horsepower is the actual horsepower of an engine measured by a brake attached to the engine and recorded on a dynamometer. Engine 101 class
 
It's the horsepower delivered to the rear wheel. I was joking a bit to much the first time I guess. :oops:
 
I guess the hp can be measured at the rear wheel or at the crank depending how the test is made

Hi Sharpy,

1085cc, cleaned up ports, 3 angle valve seats, Stage 1 Kent Cams, 36mm Mikuni RS flatslides, Eagle exhaust, welded crank. 1978 or 79 8 valve GS1000 in a 750 chassis equals 110 bhp at rear wheel (Dynojet 250 dyno) or 114 bhp if I take the K&Ns off and go up a size on the mains.

Please don't rave on about this and that, just state # of valves , state of tune and hp figures please thanks
 
Raving on is it here! I have a setup similar to Brit but only with 28mm carbs. Havn't bothered with a dyno run. Comparative numbers are not very meaningful unless run on the same dyno the same day. It seems to go ok.
