after many many hours of searching the internet, on both versys and other bike forums.
Having examined and reviewed their fixes for FI leaning out the mix caused by the closed loop, o2 sensor etc.
looked at reviews and reports on memjet modules, PCs, others
I decided I wasn't going to have another British summer haunted by this annoying trait.
After reading up on resistors, potentiometers, checking the versys manual for allowable voltages etc
I purchased a couple of potentiometers and a mulitmeter and decided I was going to fix this one way or another.
Anyway Today disconnected O2 sensor plug at side of engine, and just for to see started it up.
No major disasters, yes FI light was on as expected.
Having read about it, tried the starting the engine before the FI boots up completely, yes that worked, engine running no FI light.
So again just to see I took her for a half hour spin, completely different bike,
I'm a lot happier
No surging, engine running very smoothly, when caught in traffic burbled along at 4k revs nicely, no snatching at throttle. Less engine braking as expected with more fuel in the mix.
Seemless transition from low to high revs.
No strong smell of fuel when i got off, or coming from exhaust at idle.
yes i expect fuel consumption to rise a bit
Not counting any chickens just yet, but i'm hoping perhaps ?
what do you think ? potential disasters ?
