Is the 1125R stock muffler really that bad?.... Well no, for a stock boring muffler that you don't want to get power out of.
 
stock exhuast on any internal combustion engine from manufacturer, regardless of how many wheels it has WILL ALWAYS UNTIL THE END OF TIME = way to restricting, potential of power needs to be unleashed with an exhuast that allows the engine to blare itself at the top of its lungs and clear its thoat of the exhuast pouring out of its valves

dunno if that helps at all.....................
 
The stock pipe is purpose built part. It kills db's which in turn hurts performance. It flows good for what it is. The "EPA" tune that comes stock on the bike is weak. A EBR ECM u will notice a difference in performance and drivability at low RPM is much improved. If u want the ponies ur going to have to replace it at some point. I would recommend a Keda-Design pipe but do ur research and find out what u like.

the stock muffler is a real pice of art, complying with noise and emission standards, meant to last for a VERY long time. But that doesnt mean i'm not taking it off as soon as i get back stateside for a Barker...
 
im not sure that the ebr ecm is the way to go....why not log the rides with the stock and burn new fuel maps to it?
From my understanding you cant do that with the ebr unless you drop the 750$ and you still cant log only tune with a dino. Not what I want to be doing....
American Sport Bikes shoot out shows 121.6hp at the rear wheel with the stock map the barker only shows 125...The FMF actually lost HP!
So, my question still stands whats a good tune for the stock pipe do for it?
 
It's hard to say what the numbers would be after a good tune. You wouldn't lose any power or torque, but you might not gain huge quantities either. It really depends on your bike and your riding environment. It would certainly greatly improve power delivery and rideability, which would likely feel like a real gain in numbers.

Only one way to find out! If you book my Tuning Package 3, you can get a custom tune on your stock exhaust, and learn how to retune your bike if you ever choose to change things up and put something aftermarket on.

That pipe Jeff posted, EBR's ecm with the matched map on their dyno and a very abused dyno bike made 143 hp. The shootout showed mine at 137.8 hp, so squeezing out a little more isn't too much work.

You can tune on a stock ecm, I've seen it done a couple of times. No reason why you can't do it on a dyno, but that costs whatever the hourly rate is. You need to (or should) buy wideband O2 sensors and controllers to do it right, EBR already did that and got it pretty close. I bought sensors and controllers for mine, it was almost $600 I think.

I don't remember who did it, but I think I saw or heard of a stock pipe hitting about 134-135 hp when tuned. I don't know what EBR's tune makes for it. I've seen the results from 6 pipes (DSB spec, FMF, HMF, Barker, Drummer and mine) from them and I know which one's make what. I was surprised (pretty happily) to find out mine made more than anything else out there except for a full race system. Looking at the ASB shootout give a pretty good idea of where things stand, although there's a 3-4 hp gap at the top.

I'm starting to seriously think about doing a full system, I guess there's maybe 4 serious buyers if I build it right now. Pricing will be the hard part. EBR's $1800 kit makes a known amount of hp on an otherwise stock 1125 (144-145) but it's also good on the 1190 as well. Those have made 175+ hp, so it's something to shoot for, although that included timed cams, headwork and who knows what else to get there. I'd settle for 155-160 on a big bore kit and pipe.
 
I have 2 in the garage right now. Mine will be torn down sometime in Jan for a valve check, That's when I'll probably look into it. The owner of the other bike offered the same thing, his has all the plastics off of it now anyway and is in need of the valve check as well.
