2017 RC 390 Long story short, I installed a PCV with WB2, K&N air filter with MT open air lid, straight mid pipe, cheap slip on with out baffle, and map from Rottweiler for open air box and comp exhaust. Bike will not stay running at idle, and struggles on all gears unless I’m wide open in 5th...

I thought I saw somewhere on here that cleaning the throttle body might solve the issue of the bike cutting out while downshifting(?). I only experienced it downshifting to first. I'm not sure if the issue would occur in other gears. Is there merit to taking the throttle body off and cleaning it...

. So now that the PCV is installed. it was time to install the Dyno Jet Wideband Commander 2 ( WBC2 or WB2) p.n. 15-7023x........ so we could have more Control over the Fuel map on the bike. As many of you know the KTM 390 has a difficult ECU that doesn't allow closed loop to be altered...
