Could you point in in the direction of this disabling the secondary air injection I keep reading about?Had mine out on some forest roads yesterday, no popping at all. I have not touched the air injection system .

You tube isn't narrowing it down and neither is the search here. Lots of dead links.
Thank you sir.Follow this link. I did a tutorial. Scroll down and you'll see it.
2022 KLR 650 EFINow we getting somewhere. Yes the moped trick clean out the header flange weld and port match. Block off plate with resistor. Yosh pipe and slick...www.advrider.com
The air injection is supposed to flood the exhaust with fresh air when the throttle is closed to go ultralean and Hypothetically burn off unused fuel. What happens is the oem catalytic converter and muffler also gets really hot. We can thank commiefornia for this gem.Thank you sir.
I doubt I'll do the mod, no decel popping (yet). But no lighter and better exhaust either.
If I change my exhaust and experience the popping I'll know where to go. The running cooler someone mentioned piqued my interest.
I mean is it improved throttle response, or how "rides like a totally different bike'?
You need to make a correction Tom. The MC Mod involves Advancing the exhaust timing.For example, the highly-touted but bereft of proof MC Mod involves retarding the exhaust valve timing. That removes a lot of engine braking as a side-effect (while at the same time increasing cranking compression due to mistiming of the KACR).
This Closed Throttle Fuel Cut became a thing for emissions on bikes that needed to pass the 2008 standards. So many bikes of that era, ended up with that crap and so many of them ran like crap during that transition on/off throttle. I recall, manufacturers struggled with smoothing it out. I recall, my 2007 VFR800 was horrible, until I fixed it using a Power Commander. I also had other bikes and they all sucked like that. My friend's 2006 BMW K1200S was a freakin' beast during that On/Off throttle transition. It wasn't until manufacturers started fitting secondary throttle control, using electronics to smooth out the transition, was it almost fixed. Even early models of the Yamaha FZ09, Suzuki GSX1000S, and others, struggled with this abruptness. It was a hot topic of discussion in their forums.Shutting off the fuel in the FI is done for emissions and was poorly executed (by all accounts) with the '22 KLR design.
