Fuel injected bikes started to become mainstream in the early 90's (Though the first mass market fi bike was the Kawasaki KZ1000G in 1980...) - it was early 00's when carbed bikes were pretty much killed off for good due to tighter emissions regulations.
not a choke in the true sense, just a fast idle.
nice fer when yer need both hands off the bars to light a *** and such....
Really thought it was a choke. Seems a bit pointless having a slide fast idle adjuster on the handlebar and one on the side as well doing exactly same job
