Shortly before we went into lockdown I got the major service done on the vfr1200. After paying more than a grand for this, and a few other niggly bits that needed doing at the same time I was expecting a brand new bike. Well…
The bike is running super rich. Fuel economy down big time - maybe a drop of 5mpg at a guess on an already embarassing return. It’s clearly drowning itself, particularly on start up, where it will cut out once every 3 times or so.
I spoke to the mechanic at the garage about this, and he said well it’s got a power commander V and previously had a hiflo air filter in it so would have been set up for that and the girthy deljkevic end can. He’s put an OEM air filter on as reckons the hiflo air filters are no good for the bike. Honestly I’ve only ever heard that about K&N but there we are. The power commander came on the bike and I installed the hiflo air filter 8k miles ago as when I went to replace the air filter that’s what was previously there
So my plan was to disconnect the PC and see if it made a difference, and if so find a map on google that would be better suited. I lifted the seat up to see the lead snaking off under the tank somewhere. I can access the pc itself though from under the seat.
Does anyone have any experience with issues such as this and know of a good solution? If I can I’d like to keep the power commander in place as my throttle was previously buttery smooth through traffic and I want to keep it that way (not that it is anymore since it’s been playing up).
I have only done about 800 miles on the bike since the service but it’s been about 3 months (basically two weeks of commuting then haven’t ridden since we got sent home). I don’t know if I’d be within my rights to ask the garage to sort it out, as they’ve done the work to an OEM standard and it’s the after market PC seemingly causing issues, and even if I were, I don’t think I’d want to do that to an indy business that’s just been ragged by coronavirus impact.
