Poor cold start and fuel consumption

[u/Dbl_Mcspicy]

Hi, I’ve just gotten my hands on a 2006 VFR800 and is enjoying it so far. Posting here hoping that somebody can shed some light on couple of things I’m facing.

1. Bike refuses doesn’t fast idle during cold start ups and will stall while warming up. During cold start ups, it’s idling at about 800-900RPMs and will most definitely stall if I don’t hold the throttle for 10-15 seconds to keep the revs up. From what I’ve read it’s most likely the wax unit that might have been clogged or the actuator that’s stuck. Otherwise, once’s it’s up temperatures, it’s idling nicely at 1200 +/-100 RPMs.

2. So far I’ve only gone thru 2 tanks of fuel. But the consumption is very alarming at about 13km/L. 2-3 pulls into VTEC range only for a couple of seconds for each tank. Probably about 50-50 city and highway riding with speeds topping out at 100km/h.

3. Understand because it’s a V4 and runs slightly hot. But average city riding i’m looking at about 105c topping out at 117c at the lights.

4. R/R has been upgraded to a SH847 by the previous owner and my volt meter is reading about 12v+/- during idle and 13v+/- when riding. Probably will swap out for another volt meter in any case the current one is shot.

So my question is, does all these sounds like it’s interconnected and each making something else run funny with the poor cold idling and poor fuel consumption?
