StrykerEnvyNoMore so, I did this yesterday. I can tell a lil difference . drivability is better, acceleration a lil sluggish maybe from low rpm. ill ride a lil and check plugs, maybe just replace them while I'm there. c1 +14 c2 + 16

Its easily seen after you remove the battery and tray.

gerdawg Leave O2 in (at least I did), no resistor. With the O2 out you'll be running really rich in a lot of scenarios. I'd do what you said, back to stock and do CO adjustment. The bike certainly runs better with the mod and it lightens up a bit of the twitchy throttle/chugging.

If you have extra scratch, go with Ivan's ECU tune though...it most certainly makes the Stryker run the way it should have from the factory.

StrykerEnvyNoMore so leave the o2 plugged up with this mod?? what about the resistor? remove it? leave it? I'm currently running unplugged. loses performance but drivability is better. I'm guessing back to stock and then increase values with CO adjustment..
