Just double check your oil and coolant levels and also rear tire pressure.
Or know how to block it because sometimes the dyno operators don't know all the bikes.I would make sure you have done the pair mod prior to Dyno tyning.....
Yea, I have a buddy with an 08 GSXR750, and that was a mod on their site to plug the pair valve.Never heard of the marble technique, but whatever works.
The pair system injects air into the exhaust system for emissions and will give a false reading to your dyno operator if left operational. It has to be plugged or removed so that the tuner can get proper air / fuel ratio readings.Whats a diverter valve ?
