Hayabusa 2gen pops & bang

[Mr Brown]

Well that certainly backfired ... it was meant as a joke, you know, in the spirit of the Fast n Furious franchise. the GP bikes don't actually pop on decel. Anyway, I won't be quitting my day job anytime soon

Au contraire mon frere....

all kind of backfire is not very nice to the exhaust valves and can cause violent costs .

the racers don't care - their mech. guys do the repair and their sponsor(s) pay for that.

if you only wanna flames inject some extra fuel to exhaust and then light that (by a spark plug or so)

I add 16% fuel in lowest tps angle, no effect

One of THESE has to work. I read it on the internet.
Rubb.

You have the Pair removed, you won't get the popping....put the Pair back in if you want that noise.

It's not as simple as adding fuel. What kind of exhaust you have makes a difference, so does timing.
Why do you want it to do this?

This can cause difficulty in AFR tuning if you ever need to do that.

I'll bet you could tune for decel pop. Add fuel to the 0% throttle position at whatever rpm you want the pops at. I have heard of one guy removing all fuel at 0% TP except for idle speed to eliminate decel popping from his ZX-14. That bike decel pops a lot. My busa only does it if the pipe gets very hot, nothing like what we see in those videos though.

My 14 is a total PITA with deceleration pop. I need to get in there to the power commander that bikes been so lonely

@Kevin Jones Come to think of it, I noticed a reduction in decel popping from my 14 just by blocking the clean air hose. I just pulled it out of the bottom of the airbox, stuck a dowel in there, reinserted the hose and hose clamped it so the dowel would stay put. I'd say I got about 20-25% less popping on decel. After removing and blocking the PAIR, there was no further inprovement but going PAIRless is a good weigt loss and it opens up some space on top of the engine. I don't know if you can mess with the PAIR on a Gen2 ZX-14 but the Gen1 doesn't need a PAIR.
