Poll - 449/511 EFI butterfly removal

Ha ha, cool.

A motorbike mechanic mate of mine has an funny saying he rolled out when I told him about mine.
'Parts removed cost nothing & cause no problems'!

Meant to be 'tongue in cheek' but might be true in this case I think.

I removed the fly by wire butterfly from my 2012 TE449, now my throttle has no brain I get to do it myself. I like it! The bike has much improved throttle response and it seams to start faster, no waiting for the computer to make up its mind.

I am concerned that my bike may be emitting more carbon.
So I am going to stop eating beans in order to limit my methane output.
This should keep my carbon footprint at about a size 9.5.

Ha ha ha.
I had concerns too, Radar!
I have planted some thyme in the garden , so I'll reduce my carbon footprint AND have more thyme to ride!!

I had a custom map on my 511 SMR (PCV) but I still had the occasional flame out, now my flame outs may be different to everyone elses. I never got flame outs straight off the throttle but I would get countless flame outs/dead throttles when I was clutching up wheelies. Since removing the 2nd butterfly I havent had a single flame out

The 'dead throttle' is the second throttle not opening up.
Can't happen if the butterfly isn't there!
Awesome dude, glad it is working for you

Don't forget to cast a vote in the poll.

Pull the EFI butterfly out of mine last weekend. Cant say I really noticed more power or power delivery, but it has 100% removed the dead throttle problem, which is what I was chasing.

I did wind my Air bypass back in about 1/2 a turn (was out 5 3/4) thinking I could run it a little less, but found my flame outs came back on tight single trails. Move it back to 5 3/4 turns and no flame outs, and now no dead throttle. You could say its "like a new bike should be".....

Bike is 2013 TE 511, Map 3, Australian delivered with RACE MAP II.

Cool. Yep, FBW throtte can't be 'dead' if it isn't there!

So it wasn't snappier down low for you, as in quicker to respond?
Removing the butterfly doesn't make more power outright, it'll be the same, but certainly made my bike snap like it should be when cracked open, not doughy.

Pulled the butterfly today. My bike has map3 and fmf power core. I did not adjust the TPS or idle. It ran good before the removal and better after. With these 3 mods the bike runs strong. One of the best changes is hot starting. I was having difficulty with that. If I added a little throttle it did not help. Now I can add a touch of throttle and it fire right up. Doesn't seem to make much sense with the fbw butterfly being open a bit, but it did make a difference. From the bike purchased to now is night and day improvement.

Rode my TE449 last weekend with butterfly and engine brake stud removed. Heaps more fun to ride now. Much more responsive, I love it.

The way they should be!

Hey Motosportz, did you break off the clutch bleed nipple too?

You do not have to remove the throttle stud. You can just do the butterfly first and see how that is. Removing the throttle stud gives you lots of engine braking and prevents 'hanging idle'. I believe Kelly just did the butterfly and not the stud.

The guys are correct. You can do just the butterfly & have a have a test from there. Even if it needs a little tweak on the JD, I think you'll be surprised by the results. I still have my butterfly......in a bag!
It won't ever be going back in ha ha.

I remember many years ago, removing secondary butterflies on a GSXR1000, and it was very effective.
Suzuki, and yamaha had those secondarys on their superbikes, I think to give smoother throttle response,
and maybe to keep the newbies from flipping them over, LOL!
