R1100GS, 1998, 52,000 on the clock. Almost fully worn Heidenau K60 tyre rear was to do dyno machine traction.
Did better than i expected. Put a racing can on, very old one, from 1990
, but compared to stock it's light as air and i put decibel killer in it, otherwise helmet would vibrate on your head while riding 
. I'm testing it for the third world sheet fuel tolerance use, since i clogged the CAT and poisoned the Lambda sensor with Iran fuel last year on the stock exhaust.
Dyno measured 51.5kW from the back wheel. It's a 18% loss from the shaft drive (chain is 11% power loss). So it does 61kW (82hp) from the crank (factory spec is 58kW!).
Interesting is that the torque and horsepower peaks get together virtually at the same time which was surprising for the dyno guys and very good spec they recon. Meaning the racing can+db killer for proper amount of engine back pressure+OEM (paper) air filter fit together well. Looking the R1100GS dynoes with stock exhaust they don't mach, horsepower peak comes later than torque. Didn't put K&N filter on, it gives too good breathing for the engine and it takes away some low rpm power and adding more top end which i have no need for.
It wrenched torque 87.1Nm from the back wheel. It's 103Nm from the crank (factory spec is 97Nm).
I adjusted TPS a bit (to 0.375 volts as a medium fuel/air mix), but that created a slight drop in the 3 to 4K rpm range with the racing can. Must see if i can make it better, altough it's not very noticable on riding.
15£ per dyno run service we have here, fantastic way to get the overview from your bike's technical status
All the factory "horses" are there on mine after 50K of riding, it did even more horses acctually than the factory specifies, so it's properly run in now? 
. Uber reliable engines those 11xx boxers are, probably no need for the top end overhaul less than some 200,000 miles or so
