Is the m4 slip on brand new ?
2013 zx6r mapping M4 gp slipon
So, there is still a foot of snow out there, but many of the roads or clear.. So i had a chance to insure the zx6r and test out the mods i have done this winter.
I talked to a local shop, and i wont be able to get in to get my PC5 mapped for a few weeks, as they are booked solid until then.
I loaded a pc5 two brothers slip on stock air filter map from the PC website..
up past 5k rpm she runs great, but lower down, 4k and below, she backfires like commercial popcorn popper upon decel.
i am going to do a little more work on it later today (its stored in a garage about 20 minutes away due to my house and road having about 2" of ice still.
anyone have suggestions on how i can get it running a little better while i wait to get it tuned? i was thinking of reloading the stock map, but any other maps that may suit it better? Just looking to get some ideas before i head out.
the only mods to the engine will be PC5, and m4 gp slip on, (still have cat) air filter is stock.
Engine temp was holding around 163F
outside air temp was 28F
Took it for a ride out to the highway and on its way out, it sounded like the popcorn popper, once it hit the highway, it was great. Very smooth acceleration, and deceleration. And back into town, back to the popcorn. Definitely sounds like a crappy map for the bike.
edit: that was running with the removable tip out. I have both the one that came with it, and the stage 2 tip that i can try for some added back pressure.

yes. Right out of the box last month. First time road testing it
Mine popped like crazy for the first few hundred miles until it was nice and carbed up now mind you I don't have a pc5 or bazzaz yet, mine still pops on decel due to way Kawasaki has ECU dumping fuel into motor upon decel .... Another this is .... So I've heard its a good idea to do the smog delete as it interferes with the PC5 and doesn't close the loop of burning extra fuel, that's what I've heard not solid facts anyone hear different ?
i normally dont mind the decel pop. my 650 does it with the muzzy, but the way this one is popping is just ridiculous.Mine popped like crazy for the first few hundred miles until it was nice and carbed up now mind you I don't have a pc5 or bazzaz yet, mine still pops on decel due to way Kawasaki has ECU dumping fuel into motor upon decel ....

maybe ill just play with the remainder of potential premade maps i have avail for now.. and if nothing reduces it, ill just live with it until i can take it in for a proper tune.
though if anyone has input on that smog delete i may be interested in that.
Do you have the power commander program on your computer to adjust the map?
divide the RPM range into thirds, highlight the first third and add 5% fuel. This is done by clicking the up button on your computer. Each click is one percent.
Load map and go ride. Repeat with middle third load map and go ride. Repeat with top third of RPM range load map and go ride.
Before you start take note of every fuel cell that is zero and keep it at zero when you save the map. Example if the throttle position at 20 % for 15000 rpm and the fuel cell says zero and you add 5% to it, return it to zero.
The map you now have loaded off the website, do not make it leaner trying to solve your problem.
FYI i had my bike on the dyno and mapped for pump and U4.4 (which i never use) and it backfires once in a while on deceleration. It is a race bike.
Good luck, it is always a learning experience!

While I understand what you're getting at.. Wouldn't the decel pop be due to richness? And adding more fuel cause more pop?
I'm sure I'm wrong. I'm just curious as to why you suggest what you suggest

In any conversations i have had with Power commander, they always said increase fuel. Don't lean it out unless you have it on a dyno. Leaning it could damage the bike, making it richer is not as harmfull.
Always go back to the zero map when in doubt.

Fair enough. Maybe I'll reload stock and try what you said
Did you delete the kleen valves on the motor? I know those are a big cause of popping on deceleration, and you really notice it after adding an exhaust.
You will need to remove the emissions and get some blockoff plates problem solved.
Yep, it will completely eliminate the obnoxious popping and make your bike sound like it's running 1000000x betterYou will need to remove the emissions and get some blockoff plates problem solved.
It's easy to do and a cheap mod
I have read that I can plug the airbox hose that feeds the pair system for the same effect.
Pros and cons of that vs block off plates?
Am I safe to do that until my plates come in?
That or is the popping harmful? I can live with it for now. But it is fairly embarrassing for how bad it is.. Lol

I think I'm going to load the stock map, as 90% agree that a stock map plus slip on won't run lean enough to cause damage.. At least until I can some block off plates and a tune.
I just want to make sure I'm not harming my motor.
How much popping is too much? As I stated before.. As soon as it hits 4k rpm or lower it sounds like a war zone.. And that somewhat worries worries me.
Should I maybe pull my plugs and check them? Or is what I describe typical for a "good enough" tuned engine with no block offs.

So if I were to go with just a slip-on (like the M4 or the Two Brothers) would I have to do a PC5 or will it run fine with everything else still stock?
:rant
I don't even know how this is even asked anymore. No, you don't need a fuel controller or any adjustments in fueling for a slip on. It will run fine regardless if the slip on replaces the premuffler or not.

You could run the slip on with the zero map, there won't be any issues. The reason people like me suggested the block off plates is because you wanted to stop the popping.I think I'm going to load the stock map, as 90% agree that a stock map plus slip on won't run lean enough to cause damage..

You honestly don't even need the PCV. I don't know if you're planning on decanting the headers but right now it's just added weight.
The whole point of me buying the pcv, was so I could delete the cat and run a aftermarket filter down the road and have it tuned right.
They were on sale, and I knew down the road I would need one. Probably next year.
I also liked the fact that a lot of people report a smoother accel and decel even when stock, with the pcv. Hence why I want to get it properly tuned even with just the slipon.
However I may hold off until I gut the cat.
For now I just want to get the popping under control. I don't care I'd its still there. I just don't want it to sound like the thing runs on backfires alone.

Then as said already block off plates problem solved.
roger that.
already on order.
it seems people are fighting left and right with these block off plates.
sifting through all the YOU NEED TO DO THIS AND NOT THAT crap... it looks like..
pull of the stock plates with the sensor. Jump the sensor, plug the hole that will now be void in the airbox, bolt ont he new plates, and good to go?
lots of people saying be careful with the crank vent as you'll explode your bike etc etc... but from what i can tell, there is no modification to that system by installing the block off plates over the reeds. So i can assume just hook it up into its typical spot and be done with it.
am i missing anything?
