Running lean (I think)
So I'll start off by saying don't crucify me, I've sifted through all the posts I can find but didn't really find exactly my symptom. It's not the clutch basket problem (Which I definitely have and will need to address), and it's not a constant flat spot in the factory tune as that would happen at all throttle positions.
What I'm experiencing is a slight lean out condition, or what I'm assuming is it running lean, anywhere from 2.5k-4 at cruising throttle or very light throttle. Just a light surging and if I let off the throttle when it happens some slight pops from the exhaust. If I power through it it's perfectly fine.
I have a Leo Vince exhaust system with the baffles out. If I put the baffles back in it definitely helps, but it's still there.
I'm coming from the land of carbs so I know a lean condition from tuning them, but my question is shouldn't this be well inside the stock tuning parameters? You'd think the FI would be able to account for the slightly more airflow an aftermarket exhaust would give. Is it a pretty primitive system?
Could this may be tight exhaust valves? Bike has 60,000km on it and the last owner wasn't aware of the valves ever being adjusted. I couldn't find any threads that explains the symptoms of a needed adjustment.
A power commander was always in the future for this bike so if this is just a classic lean out condition because of the exhaust and stock tune then I'll just bite the bullet sooner than I planned to.
Thanks guys, loving the V-strom life so far!
