Poll - 449/511 EFI butterfly removal

I want the beta cross trainer....Sick of all these valves and stuff

I like valves, just not in my inlet tract connected to the ECU

It is one concern of mine with the new Sherco that I will be digging into PRIOR to purchase. they are running out the same

'ECU controlled smooth power' line Husky used with the TEs...

None of that rubbish on the Yami or Suzi, both are end-user tunable systems

G450X running Akro and PCV from day one, have not had flame out/hanging throttle issues, this does not seem to be the same issue it is on the TE for some reason. However I have always been disappointed in initial throttle response. Had my first and only (hopefully) flame out yesterday so pulled the FBW butterfly and left the idle up arm in place. Still starts instantly hot or cold and throttle response is now brilliant. I will try some accelerator pump settings as well, but wanted to try one change at a time. Thanks DM.

The accelerator pump on the PCV is abrupt, especially with the butterfly removed. Start small and work your way up.

I started big thinking it worked like the JD Accelerator Pump, and almost looped the bike on several occasions after turning on the PCV AP. If you are woods riding, I think a tiny bit of AP just past 0% throttle would be good. Anything beyond that and you are playing with fire, in the woods.

Thanks for that, I was going to start with the settings on Tinkens 511 map?, what settings did you settle on?

Thanks Campbell

Haven't decided on a setting yet. I have to get in there and play with it more. Last time I had it hooked to the computer I was setting up the AutoTune and forgot to tweak the AP. Besides, my 2T has been getting all the attention since then.

I want one of those stickers too!
Where can I buy one?

Edit.
I worked out not long after this post, the map sensor plays no part in the fuel mapping while running.
As far as I'm able to tell, the map sensor is only used to give the ecu an atmospheric reading after key up, PRIOR to starting.
I've run the engine with the map sensor hanging by the wiring & the port blocked. It ran perfectly.

Regardless, the bikes run well without the second butterfly.

PM me I'll get you some.
