Yes, they are fuel injected but the the V92 likes their warm up time (about 2-3 minutes, summer getting into it easy out of 1st works best for me). Wait until winter gets here and you are next to a Carbed bike and listen to their hassles vs yours.
My start up in warm weather is ignition over with no fast idle, fires up within 2-5 seconds and just let her idle as I am putting my gear on/getting set for the ride. Maybe crack the fast idle just a hair if you want.
Kill the fast idle if I had it on, a couple easy blips on the throttle and off we go. Not so say it may be a little slow on the response until you get past the first mile and I love my leaning so slow and sure wins the race for me. Once at op-temp, runs like a scaddle ape.
Winter start up, open the fast idle just a tad, start and bring it up to about 1300 rpm. 2-5 minute warm up as I am gearing up, keep fast idel on for first mile as I am heavy residential and alot of turns, etc. Come from work, just out to the main road then kill the fast idle. Again, once op-temp (5 min or so) she runs great.
If your getting backfires from blipping cold or not, just the nature of the engine from what I am told. Rarely after a good warm up for me. Hope this helps, safe riding!!!!
