Removing the secondary flies-Question

[Evert]

Just flies out seems to make the bike feel normal, or what you would expect. Gets rid of the bogging feeling. If it were lean you'd know it right away when you backed off the throttle at any given point, because it would surge.

I agree with your assessment and know that there is at very least one forum lurker out there who told me he put 60,000 miles on an '08 with flies out and nothing else.

I have nothing against pc's or the guhl reflash except the cost, especially if you live in Canada. Took the flies out myself and have no doubt Connie and I will live happily for a long, long time.

that seems like a valid answer (albeit anecdotal) to the OP's original question...

Uh, Posts # 2 and 7 did.

Indeed, but they contradict each other, so...?

Based on what I read here, I don't think that you'll hurt the bike by pulling the flies and leaving it at that.  If you don't like it, then get PC.  Or you could just get a Guhl reflash and leave it at that.  It's really whatever floats your boat.  There is no wrong way to do it.  The only issue that I see might be if you mess up pulling the flies out.  There have been some problems reported by members having issues getting the screws out or bending something up.  Depends on confidence level and using the proper JIS screwdriver.

OK, so an analogy-you go to a hooker house, the goal is to get laid.  There are two options, one is very pretty, but has smaller headlights, the second option is drop dead hot and large, yet perky headlights.  What do you do?  Go with the pretty free one or pay a bit more for the drop dead hot version?

Reminds me , 18 years ago I'm walking  into my Hotel in Warsaw Poland and the most beautiful girl is near the elevator , Hi I say ... one hour,  two hour,  ALL night she says 

Well I never touched her  ( never did the whore thing ever) she did show me the town  drinking  dancing and I spent the night at her place, good clean fun.
She said she was dirty so I guess she had something I did not want to go homee with.

OK...I am going to remove the dadbern flies, so what do I do along with it, install a PC V? Too much info here on this thread for me, I'm not real familiar with all the fuel mapping stuff.
Thanks

You don't have to do anything.  Removing the secondary butterflies is something that can be done without any other mod.  It doesn't build on anything else, and the change is significant on its own.

Good read gents, couldn't put it down. 
Nice ending MOBlues
I have a decision to make now flies out or flies out with a PC V.
I had a PC III and Yosh pipe on my Bandit 1250 and it helped. Then I added a Header, filter mod, took the flies out ( couldn't bring myself to putting a hole in the headers for a O2 sensor) changed the PC III to a Dubec EFI box(tuning on the side of the road with a flat screwdriver)  and huge difference. The bike lost close to 50lbs with the exhaust change and the removal of the centre-stand. It  actually climbs the chain in second gear now.
Anyways back to the C14 I guess I answered my own question, but all info in this  thread has definitely help me think of which way to go.
Then there's the reflash!!! Hhmmmm?
Leaning towards the PC V with auto tune because of all the Mountain Passes I travel through. My FI light came on on  decent a number of times this summer. Hoping this would be the cure.

If you add a PC and download any map, whether it's for the ZX or the GTR, you will see in the map that they take fuel OUT with the flies removed.

So the worse case you have, with the flies out, and no PC is a slightly rich mixture which will not hurt the bike... more fuel cools the valves and might blacken the exhaust pipe IF you run around all the time at 25% throttle and under 4000 rpm.  That's where the map take out most of the fuel.  Big deal.  Much to do about nothing.

The only reason the take out the fuel is to gain a few hp in that range by running a lean mixture for optimum power.  An added 2-4 hp in that range.  But by taking the flies out, you added 20 hp, even with the rich mixture... so your huge gain is in losing the flies.... the PC just adds the cream on top.

The OP was for a 2008 that has no TC. Mine being a 2014 has TC and I am curious how much removing the flies will affect the TC. I'm sure I read somewhere that the TC uses more Fuel control then the use of the secondary flies when activated.
Any thoughts on this would be appreciated.

Reflash the ECU at Guhl motors and you don't have to worry.

New to this discussion.
Read it over quickly and will go back to reread in detail.

Have 2 questions that I don't see answered in my quick read.

Cost; What is the cost of "remove Flies and add PC" vs "Guhl Reflash"?
Warranty: Do either (or both) void the bikes warranty?
                (I suspect the reflash would be harder to detect and less likely to void a warranty)

Ride safe, Ted

Ted, the reflash is the way to go for anything after a 2010. The reflash is, iirc 375.00, to properly set up a pcv and autotune you're going to be closer to 650-700.00. Steve

[connie_rider]

Thanks. Fred highly suggested that and I was leaning towards the reflash anyway.
But it will be down the road after I get some miles on the bike.

Just wanted to know the difference in cost.

Ride safe, Ted
