Not sure if anyone has done it yet but have you installed the Pro Taper adventure bar on your CR like Erik has on his personal 1190SX. I currently have the factory high bars so wondering will the current cabling and clutch and brake lines be long enough or will I have to buy longer ones.

Also my Barker exhaust is due for a repack but have thought I might try some other exhaust as I really dont think much of the look of it, Really looks like a add on and not OEM like others do? I have heard and read the exhaust comparison that was done years ago but not sure if many of them are still in business or if they make the exhaust for our bikes anymore.

I have said this before and I will state this again, there are very few aftermarket exhaust systems better than the stock system for the street. Aftermarket systems typically produce slightly more power over the stock system by optimizing power at WOT in a very tight engine speed range that on the street you very rarely get the opportunity to use. This comes at a cost of very lean running, less mileage and poor power and torque in those engine speeds you do use. I cannot say all after market exhausts are bad, I have not tested them all, but certainly Barkers are crap.

In the days of carburetors, this was easily overcome with jet changes to some degree, but when ECUs and fuel injection was introduced, this compensation became difficult, if not impossible to do without disabling closed loop operation. This is because of the exhaust oxygen sensors are always forcing the ECU to achieve stoichiometry in closed loop operation. Aftermarket exhaust systems further aggravate this simple truth.

The Bike came with the barkers installed and EBR ECU to suit. As the ECU is tuned for a aftermarket slip on there shouldnt be too much difference to run most other exhausts that are available without having to reprogram the ECU unless going back to stock exhaust I spose.

Is the HMF exhaust any good. I noticed before EBR went tits up they actually offered them as a part for the 1125 on their website? Dont hear much about Jardine or FMF anymore for 1125's. The Torque Hammer looks good but I think is a little pricey as our Aussie dollars is trading like shit at the moment.

Stevel, dude, I gotta say, you are as high as a fu cking kite with those statements. Every one of the exhaust systems tested back in 2010 showed a significant gain over stock in the midrange and especially from 8500 rpm and up.

I really liked my Barker on my CR. It was well built and sounded great: ) Jardine... not so much.

SteveL, no offense man but by your own statement :

"I have said this before and I will state this again, there are very few aftermarket exhaust systems better than the stock system for the street.

You don't quite understand how fuel injection, ECM's or tuning works.

Yes, Closed Loop operation looks for Stoich (14.7-1 clean running) and that is totally fine and should be left alone*... BECAUSE it is only active when you are riding at PART THROTTLE and don't need a rich mixture (13 or so) for acceleration (power). Open loop (where you tune the pipe for WOT) becomes active as soon as you twist the gas. Closed loop 14.7 is 14.7 no matter what pipe you have and thats OK because you are not at WOT when CL is active..

That is why closed loop should be left ON regardless of aftermarket pipe or not... so the ECM can do what Fuel Injection was invented for... to automatically compensate for environment, altitude, gas quality, etc several times a second. without having to change jets in a carburetor (several times a second).

Open Loop is where you 'tune" a pipe for WOT and theres no limit to the "RPM range" you can tune at. As soon as you twist the throttle, the ECM switches to Open Loop. Open Loop is a PRESET map where the ECM doesn't look at the O2 sensor anymore and is NOT looking for stoic (14.7) because the ECM is dumping a rich mixture (even stock) to get more power. It is a set map (I won't confuse you with EGO correction) and that is why it needs to be 'tuned' when you change something from stock on the engine.

I get it Stevel I'm stuck in the past too. I re-built a Carter AFB just this morning, but the last carb'd car was when? like 1995? But I totally disagree the tuning fuel injection is hard. In fact it is vastly faster, more accurate, and even much cleaner.

Forgive the oversimplified answer, just the basics...

*as long as the FI system CL adjustment parameters are wide enough to allow it to compensate. IMO most Buells are because they can adjust well over +/-50% global fuel mapping in CL (thats a LOT): )

OP, IMO I agree with you that most aftermarket exhausts are close enough you can run any non-stock pipe tune. The OE Buell Race tune is great for any pipe I've used so far.

Theres still a lot of brands of exhaust for your Buell available, pick your poison.

I don't think the Pro taper bars are that much taller than the High bars, all you can do is try, you'd be looking at custom cables if they don't fit, but I believe they will. I know that I had trouble swapping from clubmans to high bars on my CR but thats a drastic change.
