PCV on a GSXR600 w/ Full Exhaust (no o2 sensor) and not dyno tuned - worth it?

However my bike doesn't come stock with an o2 sensor

You can get a bung installed in your exhaust then you can run the autotune (or bazzaz w/AFM). Tony from Bluestreak has the best price on PCV+AT200.

Key thing with the autotune is either tell it not to tune the very low throttle ranges (say under 10%), or keep an eye on the trim values and don't just keep accepting them if they max out in the low RPM range, it will soon get very crazy and the bike will surge and do weird crap at low throttle. Easy to fix by just wiping the map in the affected areas then telling autotune not to mess with those areas. When you're on the throttle is where autotune really shines.

Speak to someone like Pro 6 or Z1. In some instances there isn't much $$$ between a proper reflash and a custom tune.

I fitted a full Yosh syste, bought a used PCIII and got a custom map done by Z1. But thats for a track bike. Not sure I'd bother so much for a street bike.
