Bad idea. You should have your friend do it to his bike first. :P
K75 fuel injection is very simplistic. There is no reset on it, period. Nothing changes on it. That's why it is fairly reliable, but if something is off (IE: PCV hose broken) performance will suffer, as there is no oxygen sensor to correct the mixture.
What that would do is an "Italian Tuneup" which can be achieved by riding like you stole it for a bit.
Cleaning the injectors improves more than the flow. It improves the spray (a lot). This makes the engine use the fuel it gets more efficiently.
