Ignition Advance Rotor

 Adds some power at all part throttle positions. That equates to more "snap" in throttle response for you. Mileage, on some bikes, if properly tuned on the low end carburetion, will increase slightly.

State Of The Art Motorcycle Dyno Analysis Software

CBR1000, 93-96
The above graph plots power changes from red (run #3 - hottest) to blue (run #2) to green (run #3 - coolest)
Run #3(red) shows slight richness in midrange (power loss as engine warms to full operating temp) and near perfect at top end. (power increases as engine reaches full operating temp.)
Run #1(green) shows slight richness when compared to run #3(red)in midrange (power is higher when engine is below full operating temp) and probably ok at high rpm when compared with run #3(red) at top end. (power increased as engine warmed)

Even though you couldn't hear or feel it, the rough looking plots show cylinder #4 missing at 7200-7700 and 8800-9600 rpm!

Try seeing that kind of detail on any dyno other than the Tiger 950id!!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
