Could the EFI problem be self induced??

I wonder if the EFI problem is rider induced. I ride my bike very spirited. So my bikes computer learns that it should be ready to richen the mixture cause it knows my driving habits. OTOH, a person that babies their DL and drives it like an Old Lady in a Land yacht. Their bike thinks, hey I can lean this baby out; I don’t need to make power. So when the Old lady gets frisky and want to give it some power the bike is not ready for this unusual condition.. I don’t have any stumbling with my bike. (An 03 model) Now if I stupidly let the RPMs drop below 2000 In 6th gear and give it a big twist, it will bog down, but that’s not a stumble, that’s because the bike is in the wrong gear… I think many folks are confusing this with stumbling. Go get out your bicycle, put it in top gear, and now try to climb the next big hill. Your body is still making the same power, however its not being effectively used.. Anyway just an off the wall hypothesis…

The lean condition at 3200 RPM's or so is very real. You don't get a "grinding" sensation whilst rolling through that point? It really doesn't bother me anymore, but my dealer will replace the ECU next week or so....we'll see what happens!

Bike is delivered too lean, as Suzuki must meet EPA stuff.

there have been several threads about the system's ability to "learn". common wisdom so far is that it can't, or won't, or doesn't. i understand what you're getting at, but from all i've heard, the problem is an improper set-up from the factory. i think maybe "learning" is a sixth generation ability (should roll-out on the '08's.)

There's no active feedback to the ECU for it to learn anything. This might have changed with the '07 and it's catalyzer but I haven't seen anything yet.

V Strom Lean

I own a K7 and by looking at the pipe it is running very lean. In less than 400 miles it is a "golden brown" the aft cylinder exhaust looks as though it will melt soon as it is a crispy "toast and black". I will report after first service.

The EFI issue is an old one for Suzuki. Early FI Gixxers and Busa's have it FWIW.

well

i was just wondering as mind seldom drops below 3500... from 3500 to about 6000 the thing pulls like a freight train. I wonder if folks are driving this thing like a Cruiser V twin and simply lugging it to much..
