Not having the lambda plugged in.. Any issues?

I’ve taken the pc5 off the gsxr as its slowly going back to standard but I’ve left the jumper plug in the lambda sensor socket so the ecu still thinks its plugged in.

Im still running k&n air filter and the yoshi r55 cat exhaust and was wondering would this cause any issues with the ecu not having the lambda reading?

As it is an o2 sensor fueling is likely to be all over the place!!

Nope the fueling is pretty good bar a little bit jerky which is was before. been riding it since Monday like it
