on my 06 600rr with the -1/+2 sprockets on them should i set my speedo healer at the -16% or the -11.2% the -16% is what the healer says for the sprocket difference and the stock error ratio on the bike the 11% is for the sprocket change and saying the factory speed has no error should i go -11% or -16% any help is appreciated thanks

 

if the online speedohealer calculator says to set it at 16%, that's your setting. you should always go by actual speed relative to indicated speed. that's how the speedohealer works best. find a speed trap, a cop or go to the PD and ask that your bike be speed trapped. a dyno can give you actual speed as well. don't go by the estimated calculator. 11% difference is huge for stock error.

 

find a hand held GPS and use it.
