Kev, I installed the O2 converter I got from you on my '15 690 Duke, and can tell little if any difference. Unless I'm well above 3k RPM and try to accelerate in, say, 3rd gear, the bike jerks a lot.
I'm not complaining, I just want to get this otherwise fine bike to be less annoying.
I installed a PC-V a year or so ago with auto tune. So it's possible that something related to the PC-V is causing problem. The bike has a simple tube exhaust with M4 muffler (no cat) and I've opened the airbox a lot.
Unless I can eliminate most or all of the jerkiness, I'm seriously considering removing the FI and fitting a carb.
So: 1) What can you suggest? 2) If I removed the FI (maybe only the throttle body), will the ign work properly? 3) An unrelated issue -- I'd like this bike to idle lower, say 900-1,000 RPM. Maybe this can't be done with the FI, but if not, any reason I can't do this with a carb?
Thanx for your help.
