No 3 relay can be removed, It was put in to appease the German market, basically it makes the engine leaner at low revs to improve the emissions

and boy what a difference removing it makes! My Adventure is more responsive and much nicer to ride with this code plug removed.

Don't forget if you do remove it, you need to reset the throttle position sensor (TPS). You reset it like this:

Engine off
Remove the code plug (relay 3 in Quattro's pic)
Remove fuse 5 for about 20 seconds & then re-insert it
turn the ignition on
twist the throttle grip 4 times fully open/fully closed
start bike & go for a ride

Enjoy the difference. The only downside is my fuel economy isn't as good - but with such a performance increase, it doesn't worry me

great, thanks, that was exactly the info i was after....

i fitted a y-piece and did the above a few days later, the y-piece made a noticable difference but not so the plug removal.... strange.

If you put the code plug back in do you have to reverse the ignition on twist throttle etc procedure?

As far as I know -yes. If you dont do it, the motronic fuel mapping isn't optimized. When I fitted my spotlights I disconnected the + battery terminal and forgot to reset the TPS. The bike felt lethargic and I thought I'd somehow cocked something up -it took me a while to figure out that the throttle sensor needed re-calibrating.

It only takes a minute so it's not really a problem to do.
