Is the m4 slip on brand new ?
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 .... 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 ?
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.
:rantSo 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?
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.. 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.
