alright... did some research, looked around, peered around... and cant quite determine if this has been asked an answered.

I would like to replace the the two o-rings on the injectors, or put it this way... ensure I have o-rings on standby when I remove the existing ones.

Bike... 2009, 103, Fuel Injector Assembly w/ o-ring PN 27609-01B.

Anyone have this info on standby?

 

I understand your concern, being in there and not having them.
I've been in a bunch of intakes and the o-rings always look fine, even after years.
No doubt they can go bad but I've never seen one. Yet.

Parts finders don't seem to list them separately but I bet if you hit the counter at either HD or an automotive parts store you'll be able to find them pretty easily.

Good luck.
