I'd say if the bike starts in gear with clutch pulled in, should be fine. Changing the lever itself could break the switch timp off but grip only, no problem. I guess, just clear the codes and see if they return. As for ABS and no actual code, it's weird. Make sure that plug is fully seated in the area behind the Akro can and all wiring along the right lower and upper frame rail to be in good shape. Again, we are assuming it's the rear doing it. Without a more specific code I don't know. On the PCV and the AKRO map, I've looked at it. Do you find it rich and crappy MPG with that cal. Reason I ask is the leanest spot was only 13.8 or so. Main thing is it runs good with a base cal. That's rare in itself.Hi Ron,
I did coast down a long hill a while back and maybe that triggered the B1154. I also replaced the grips when I first got the bike, but the clutch side was the easy side. Really not much to mess up there.
I did install O2 elims when I removed the sensors. I'm running a PCV with the akra map.
