Sounds like a PCIII map issue. Lean most likely. Try running along at 2,000 rpm ~45 mph in 5th gear. Is it smooth or staggery?I notice mind has a very twitchy throttle responce around the 2k mark. If I am off the throttle rolling up to a light in second gear then try to get back on the throttle without using the clutch the thing starts bucking like an idiot.
Just a follow-up, now that I have a PCIII installed (and a Chuckster Intake), it no longer surges around 2000 rpm. I'd say it's the new fuel mapping that got rid of the surging.Mine does this too. All stock except for the V&H Longshots pipes. No fuel controller or any other changes (yet).
Yep. I installed the 019 map by accident. Meant to install the Thunder map and later realized I did the 019. I was comparing the 2 maps using the comparison tool and got myself crossed-up. Thunder map is next.Your mapping richened up the lean condition that usually causes the surging. Which map did you install?
Understood. I checked it this morning and the PC was reading 2% with the throttle fully closed. I reset the closed throttle setting and left the full throttle setting as-is.When you hook your laptop up next also make sure your throttle position is calibrated so the PCIII shows zero % with the throttle closed and the bike running (idling). This is IMPORTANT if you want good small throttle opening mapping. !00% at full throttle should be close but is less critical. Running along at 2,000 rpm in 5th (~45 mph indicated) is only 2% throttle opening with good mapping. 65 mph cruise is only 7-8% open. Being off a little can be alot.
