The GF would like to add that the blue flame is pretty hot on the back of her calf when it "Pops".
Remember when we were kids and would turn off the ignition while driving, then turn the car back on just to get the pop? Well, I did that a few times in front of a friends house at 3am. I guess this is kind of like that only I am no longer a teenager.
So, mapping might help. I would be interested in at least cutting it down a notch or two.

I have been doing some reading on removing the flies.
Number one concern is ride ability on the street. Any personnel feedback on this would be nice.
I have ridden for many years and have logged well over 40K in last 6 years so I am not new to the sport. My other bike is a Buell and I do love the low end grunt and the throttle wheelies. It would be nice to have that pull off the line on the 14. Yes, I am aware that the 14 will lift the front wheel under power and this can be fun but it is not like the Buell that just wants to wheelie from tons of low end torque.

rideability is great, there is no downside to removing the flies. the bike will be more sensitive to throttle input but once your wrist is calibrated it will be fine. you know you want an extra 35 ft/lbs of torgue at 3500.........

...and the Buell will still have more bottom end grunt, because it's a twin and not a 4, but the 14 will wheelie with the mod...much easier than trying to get it up now at those speeds, but if you want even more (and I mean a lot more), go for the 16/43 sprocket change after you remove the flies. That will blow your mind!

No fuel -- and if you give a tiny bit of throttle on decel, it doesn't pop.

I don't think it is a no fuel situation. It takes fuel to make the explosion that I hear as a back fire and others hear as a cool, blue flame producing "pop" .
I am thinking it is a lack of back pressure and raw fuel is exploding inside the small exhaust. Just like the old turn the car off and on while driving in front of your buddies house. Still think a map would be a fix. I was hoping that when the PC III arrived with the M- 10 map that it would be fixed. It was not.
I could be wrong this is just a guess. but no fuel equals no explosion or we just found the first air engine and we all are rich.

the mapping is giving it gas at zero throttle
gas and air = bang

Okay, gas and air in the engine is internal combustion and is how the engine works normally to produce power.
Correct me if I am wrong but this backfire or pop is happening within my exhaust system and not the engine. A true back fire within the engine would be a explosive gas charged cylinder during the exhaust stroke as in a engine that is firing out of order. That is not the problem here as the pipe is the new variable and not the timing of the engine etc.
I am no expert on this subject but I don't know what I don't know as Rummy liked to say.

Still in the dark as to what flies out means. Any light on that term?
So far I am hearing that there is no real fix for the large pop on decel. If it was a few loose fittings I would think I would have had this problem before the M 10 was installed. Has anyone had this pipe on a zx-14 and fixed the pop?
What if anthing is Muzzy saying about this issue? Or do I just need a tissue?
quote]they all backfire. its usually one big pop. lots of info on it.
I would be interested in this info.

Thanks for the link, that cleared things up for me also.

I've been running the M10 for a year or so now. The backfire is huge on decel.
Favourite pastimes
1. Find a tunnel (poorly lit), find 4500 - 5000rpm, find a mate with a good quality video camera and get him / her to ride behind.
Saftey caution
Make sure no - one over the age of 60 in tunnel whilst sending out massive blue flames
ps
Is the end cone on the M10 still hanging out????
I know this is off subject but what type of hp numbers are you getting with the m10
176hp with the m10. About 168hp before with two bros slip ons and no flies

the backfire is happening in the exhaust and it is occuring in a similar way as you described with turning the ignition off and then back on in your old car, raw fuel collecting in the exhaust. the reason for this in the car is obvious. the reason on the bike is this, when the throttle is open then slammed shut airflow thru the engine stops and even reverses direction just for a brief moment before the momentum of the engine overcomes the throttle plate and airflow resumes. during that moment when there is no air the injectors still fire but the gasoline can't burn because there was no air to mix it with. the raw gas goes in the exaust and then is ignited by the next cylinder combustion. the intensity and frequency of the "pop" is dependent on a very long list of variables. it is usually not noticed on a stock bike because the catalysts take care of most of raw fuel before it pops off and the factory does a pretty good job of tuning stuff like that out of the final product
