I'm in the process of replacing the injector o rings on my 5KT head and was wondering how exactly to get the new large (fat) o rings on the injector. Do you just stetch them over the tip of the injector? I have removed the small circlip, but the o rings seem alot smaller than the injector tip. Any responses appreciated.
