KTM 690 SMC-R, exhaust + airbox = running lean, fix?

[u/kurvix2000]

Hi guys, bought myself another 2015 KTM 690 SMCR, as opposed to the first one that got stolen, this was was not dyno tuned. Bought it with an exhaust system and an airbox delete but it's running lean. It pops on decel, engine breaking slows it down while going down steep Irish hills, and temps go up to 75% when she idles for 1 min at the lights. Other than dyno, how do you guys mitigate it? Is that a TuneECU job with some custom map I should look at? I've dabbled in some car diagnostic software and PC III in the past so i know what I'm looking it if that's the path? Thanks!

Give Gary or Karl a shout in MotoTuning, they do postal ECU flashes so cheaper than going full custom tune on a dyno.

If you do decide to go full tune, I'd also recommend them, Gary has worked on a number of my bikes & the results have always been great.
