What you all are describing sounds familiar, similar experiences! I thought I would miss the pops and occasional bang once they're gone or most likely, lessened. Major carb jetting changes are usually forced by modifications to the intake tract. The 750 ACE will lose low end power with straight pipes, but other than that the bike, because of its mild tune from the factory, is pretty much immune to pipe changes. The screws work in concert with the pilot jet so a larger jet requires less turns. Don't turn the mixture screw out too far (much over three turns from lightly seated) or you may find them missing. 410 shotgun.Īssuming everything else is right, no exhaust leaks, complete intake tract, the usual cure is to turn the low speed mixture screws out a turn to richen the mixture and/or swapping in #42 pilot jets. Now take the mufflers off and corn popping turns a whole lot louder and once in a while when the mixture in the pipes gets just right you get a bigger bang like a. The 750 ACE backfires on the overrun when absolutely stock, like popping popcorn, it is a function of the lowspeed circuit of the carbs being lean and perfectly normal, Honda did it to meet emission standards. But how great is it for the engine, is my concern. Car about to turn into your lane, let off a little (bang bang!) and we've got eye contact again haha.

I agree, I have gotten used to it, can even predict the loudness and frequency depending on the gear/speed combo which in a way is really nice. Ended up replacing the graphite bushing, solved all. Had the same with my parents 250 cc Vespa. (I do have new exhaust gaskets for the re-installation of the pipes which would take care of the suggested potential problem regarding an exhaust manifold leak. I'll be getting back to you with more info. Is there an air filter better suited for that? Or would you suggest a stock filter?Īnyhow, appreciate your time and patience. Let there be a baffle soon, it's still a lot more air out than a stock configuration. A clean filter is always a good thing however, there's no doubt about the pipes and them being open. I guess it's a good idea to start at the beginning, air intake. In the mean time, half my problem is that I have no idea where to start looking because it seems that there are many possible contributions to decel popping.

I gotta do some research about all suggestions and will need to take a look at the air filter which I'll update this post with tomorrow.

Only twice did it sound like a fire cracker went off first thing upon hitting the starter button! (Starting the engine). I would say it's more of a continuous popping on decel with the occasional louder pop/pang.
