Hello Are the flies or plates still used in the 2012 & 2013 models?
Thanks

Yes.

Thanks

Greetings to all-

This past Saturday, I bought an '08 with a full-system Muzzy and PCIII. I'm coming off of a GEN I Vmax so I'm still getting used to the power of the 14. My question to all is this: Is it considered normal/acceptable for the bike to 'lurch' at or below the 2500 RPM mark? If yes, so be it. If no, I'm curious if there's a small adjustment to be made to the PCIII.

Many thanks in advance - all the best-

Devin

If the lurching is happening at the same rpm always and it is like a sudden zing in power not coinciding with your throttle input, that has to be your flies opening. I don't know how much lower than 2500 you ride but it's possible the engine will bog if you apply a lot of throttle at lower rpm than that. You may also notice a second power spike higher in the powerband (maybe about 8000 rpm--I can't remember).

A good map should smooth it out. Self tuning will almost eliminate it. I can't say if this is the case with flies in but if you remove them, a map should be able to just about eliminate that. I can tear the throttle open 100% at 2000 rpm in any gear after self tuning and the engine spools up very smoothly.

Come to think of it, my 08 does feel very choppy at low rpm going from 0% throttle to just a crack when the motor is hot. It's like there is no fuel for for an instant and then it takes off. I think it may be the PCV's limitations in mapping the fuel table. It has always done this with the PCV. I don't remember if it did it without.

Exactly; when the motor's hot is when it occurs. Thank you for the input.

All the best-

Dj fuel tables go from 0% TP all the way to 2% in the next column. The PC5 has the ability to average fueling between columns and I have seen clear evidence of this in data logs and tuning runs. The fueling averaging function may not work so well at very small TPs. Maybe that is why dj recommends not adjusting fueling in the 0% or 2% column. I bet that is it. Funny we don't hear more complaints about this.

I only notice it when the bike is well warmed up. Much less so if the motor is cool. I don't seem to notice it when the bike is at speed. It happens in first gear and maybe a tiny bit in second. Only when going from 0% throttle to tiny bit bigger TP. Annoying, YES but I'll deal with it. Has been that way for years.

Agreed. Tonight I was out on it with my daughter (130-ish lbs) and with the two of us, rolling through the small towns at 30 mph in 3rd gear produced no symptoms. When it's just me (195), I suspect there's just not enough load so the computer doesn't know how to act as well. All-in-all, I'm not going to worry about it any further. Thank you again for the feedback.

Thinking back on this, I can almost say for sure I had this stutter even before the PC5.

Man, dying iver here....bought a 13' zx14r. Got delivered last night and only got a few cranks before the battery was drained. Anyway, my local shop told me not to remove the flies (which is a moot point since they are already gone) but he said it could make the bike much harder to start. Any input

I have a Gen1 with flies out and it starts as good as it did with flies in. The only thing I can see being a problem with starting flies out is the fueling possibly. I rather doubt it would make that much difference for startup since the engine isn't sucking air in that hard anyway. Normally tuners don't mess with 0% throttle AFR so I don't think you would find a map that would fix this. Also, if flies out makes it harder to start, wouldn't a full system also make it harder to start? I think you just have a dead battery. Charge it up. It might take a few cranks if it hasn't run in a while but a fully charged battery should turn that motor over at least 20 cranks before it starts to draw down. Just some thoughts. I'm not sure if Gen2 people are removing flies or tuning them.

My first post, I have a 2010 zx-14 i just had the flies out, PCV and new full yoshi system, after about 200 miles my bike doesnt go faster than 45 and takes forever to get there. It also sevs high when i start out, this just started happening to the bike, I am gonna take back to the shop unless there is a easy fix i can do at home..Any help

Strange one, John. Couple of home checks. Completely remove the fuel piggy. That, or swap maps to all zeros so it's back to stock. Dealer level wise, if I were the manager, wanted to make you understand how closed the fuel injection loop is, charge you to remove the piggy, or return the bike without the piggy, leave the flies out, yoshi on. I see a (+) variable even if you removed the ground off the piggy, the (-) is still at the injector grounds. It could or might not matter with the main ground removed from the piggy, but this is; 'to remove all doubt' that the ECU is in complete control.

Remove a plug and read it... wet black is oil. Dry black is over rich so check air cleaner. White porcelain is spot on... lean is mean.

Let's say what it's not:
-Flies out makes no difference.
-Any pipe makes no difference.
-ECU? And that's with a question mark saying; well, it's showing no codes for other loops outside the ECU. The ECU can still show it can start; so not the crank sensor; not the injectors; not spark advance; if it's sitting at 10° for starting; it can run the fuel pump to start. Can't point to the processor with it showing all those things.

Let's say what it might be:
-A compression check just to remove all doubt; the tail off your ass chasing that one... saying it was this all along. You missed the very first step before the wallet comes out throwing parts at it.
-Spark plugs. This is every 7,500 US miles you change out and replace the same iridium type it calls for.
-Air cleaner is so clogged up without it being changed out per book interval or less.
-PVC enters the loop and alters stock setting... is one possibility.
-Fuel pump enters the picture because of fuel demand... says the pressure is low.

67 ml/2.26 US oz. or more. That's key on, line out of tank into measuring container. Turns off within 3 seconds, so you test a few more times and see if the measurement is consistent. Have the fuel tools for a pressure gauge, that's 44psi at idle.

Throttle position sensor?

Hello, Redwings08. Try posting in the Q&A section; you'll probably get more responses there.But it sounds like your computer needs the most recent software and a remap. You may also provide the year of your bike and the sort of computer it is, such as a pc3, pc5, since I am not an expert in computers but have read a lot on our site. It is a simple remedy, and others have had it and fixed it.

Greetings, Redwings08.
