     Easyrider |
The old topic is here with all the development work: http://www.badweatherbikers.com/buell/messages/290 431/410940.html?1232660010 Besides it was cold, slippery raining, we did what we can to shoot some movies. I could't WOT in 3th and 4th gear, only wheel slip, this was too dangerous now so no wheely's. We used a very small photo camera and there was a lot of wind. Later on more pictures and movies. The exhaust is prototype II. Thursday the welding starts for the production versions. I hope to ship them soon too Pete so he can make some people very happy. The sound is great, not too loud but deep and dark. The performance is even better. The bike feels completely different and pulls very strong. Later on it will be dry for 30 minutes and we will try again.

Is it just me, OR does that thing look Huge and out of place...? Looks like it weighs a Ton.... Whats the RWHP and Torque??? Number of flashes done etc etc??? | ||

To me, it only looks large because it's sort of bright. I don't think it's any larger than stock as far as I can tell. I'd like to see it in black, which would likely make it less of a focal point. For starters, I definitely think it looks better tucked under the bike than all the other products available. The pattern we've seen most the can sticking out the right side beside the swingarm, which is a total turnoff to me. Easyrider, got one in black you could post? Looks pretty good to me! | ||

Hogs, hehehe, THE WEIGHT of the stock EURO exhaust is 10 kilo The TM exhaust is 6.5 kilo. It looks big, But in real it's not. We make with the stock ECM, not ready yet 140 HP and 118 NM of Torque, I still have to finish the mapping of the stock ECM. We will paint it in black and take some more pictures, This is the prototype II. It's more a matter How to generate performance then making the most beautiful exhaust. Also the heat inside the exhaust is a big problem, we solved, by letting the exhaust open on the top and bottom, which you cant see direct. (Message edited by easyrider on January 23, 2009) | ||

a well not to slippery for a burn out fast pas.. mind you it was very cold, wet and slippery running out to idle | ||
| Easyrider |
Pont1, it became dirty in the rain, I cleaned it with RVS polish. I make it black later when the heat is out. | ||

How is it that the exhaust on the XB's seems well-integrated and simple, but the 1125's look huge and out of place? Maybe the solution requires a belly pan to "fix" the aesthetic and performance challenges created by the Rotax design. Another thing- what is creating the heat problem... is it different from other under-engine exhausts? Did the XB's have the same problem? (Message edited by redbuelljunkie on January 23, 2009) | ||

I think it looks great, Easyrider. Clearly, you are a man with taste. The 1125 needs a substantial and black exhaust underneath it... all of the other aftermarket exhausts (perhaps with the exception of the Saron, which is too loud) look too wispy for a bike with a big black fairing and large black pods that cry out for visual balance. The stocker balances, but is a bit too raw looking with the prominent welds. Also, looks like you've got around 90 ft-lbs peak... that's excellent. (Message edited by Pariah on January 23, 2009) | ||

We are VERY interested for racing by Eric Pinson for Antelope Valley Buell in AMA MotoGT and at Willow Springs this season. To be sold by Pete at Grandstand Designs?? Very interesting. (Message edited by slaughter on January 23, 2009) | ||

dris,any set price yet? | ||
| Easyrider |
Pete (from Grandstand), will make the prices for the USA. I gave him a call and, when he is able today he will set the USA price. Later on I will post some pictures in the black version mounted under the bike. | ||
| Easyrider |
Slaughter, Let me help if you decide to use this exhaust with the fuel map for the Race ECM. I will finish it next week. | ||
| Easyrider |
Redbuelljunkie, If I was able to get the same amount of power, with a smaller design, I would do it directly. It's smaller then the original exhaust (not that much) but it's not bigger. Let's see what happens with the looks when the black version is mounted. (first the paint has to dry (-; | ||
| Helicon |
Easy, so are you having to remap the ecm in order to generate those numbers? or are you using a factory map? | ||
| Easyrider |
Helicon, First purpose remap, get rit of the lean areas. Let the engine run cooler, and stronger, and get more fuel in. Second purpose, New ignition map and new fuel map for all the area and then HP and Torque go up as well. | ||
| Slaughter |
Dris - that will be excellent., I will be talking to Scott Kellerman - General Manager of Antelope Valley Buell when he returns from the Dealer meeting in Washington DC. Steve | ||
| Easyrider |
In cooperation with airtech we will also develop a tailor made bally pan for this exhaust for the circuit. | ||
| Bud |
   made some better pictures, rattlecan black, off course the production versions will have profesional coating (Message edited by bud on January 24, 2009) | ||
| Jaimec |
Wow! Someone managed to design an exhaust system even more hideous than stock! I'm impressed! | ||
| Rah7777777 |
that is the BEST looking pipe so far!!! Fills it in well. Black looks good! I like it!!!!!!!!! GREAT job guys! -Robert www.xblights.com | ||
| Jpfive |
I like it too - and also the dyno chart. I think the runs were done w/o the solenoid, and with a custom map - is that correct? How does the dyno look with the stock mapping (latest flash)? Jack | ||
| Xb9 |
Definitely the best aftermarket exhaust available IMHO, with the numbers to match. And it is not obscenely loud. I forget how many dyno pulls Easyrider said he has in developing this, but I don't think you will find a better engineered, better performing, and durable exhaust system for combined street/track use. | ||
| Easyrider |
Thank you Jaimec... Jpfive, It is W/o Lamda and w/o solenoid. With K&N filter and Race ECM. I am now mapping a stock ECM. When I am finished I will post the dyno results on the stock ECM and with the remap stock ECM. | ||
| Marcodesade |
I hate to change the subject (I AM interested in the exhaust), but can you say a little about those front brakes? Thanks. | ||
| Bob_thompson |
I also like it a lot. Best "fit" and look so far and I am looking forward to Easyriders numbers with the stock ECM which brings me to a question: Not to hijack this fine endeavor, thanks for a great muffler Easyrider, but once again I'd like to ask if anybody or everybody that has bought and installed one of these other aftermarket mufflers has had a really good experience with the stock ECM adapting to a new system? Many theories on this matter have been put forth. I'd really like to hear from Anonymous on this or any BMC electronics engineer. In lieu of that I'll take Easyriders word, at least for his. Awaiting Kevins also. (Message edited by Bob_thompson on January 23, 2009) | ||
| Markrd500 |
Dris,you da man baby! It looks the dogs nuts man. Any price for the UK yet? Please tell me its sounds better and a bit louder than stock. Im definately on for one of these puppys. Excellent work.  | ||
| Xb9 |
stock ECM adapting to a new system? Without some comparison testing & data collection with the proper tools how is anyone to know? With all due respect Bob, asking people if they "think" they have had a "really good experience" and asking if it "runs OK" is not going to help us determine the answer to your question, it will just muddy the water. We went through all that with the first couple of factory calibrations if I recall.... Let's wait and allow Easyrider to show us on the dyno the facts, not conjecture. Be nice if the other offerings would do the same....... (Message edited by xb9 on January 23, 2009) | ||
| Easyrider |
Bob, Please explain what you mean by adapting. I try to awnser your question. My daily work is making And adjusting fuel maps, for our customers. From my point of few, whenever you change the air filter or the exhaust, you have to adjust your ECM for that specific setup. All the exhaust (good and bad) have a different gasflow/pulse, and a different demand for fuel. There is no self learning ECM system as far is I know for the Buell. I always make a stock run for the customer with the stock exhaust and stock ECM. Then I make a run with the stock ECM and new setup, most of the time exhaust and K&N air filter, And 1 run with the remap of the ECM with the new exhaust and K&N filter. Every time there are areas where the ECM needs to give much more fuel then programmed in the stock ECM. Because the new exhaust has another demand for it. The stock ECM, is not able to compensate the demand of fuel for the new setup. So your bike is running even leaner then is was doing with the stock setup. | ||

Markrd500, in the first topic there are some sound movies and in the first topic started by bud are some nice movies and a burnout. Yes it sound deeper and darker the stock but not too loud. The price here in Europe is 640 euro excluding VAT. There are discount possibilitys for the UK because we have no distributer there. | ||

+1 Easyrider. Someone explain to me why one would think if they change intake and or exhaust flow, something magically happens inside the ecm and it suddenly knows the correct value for each of 320 different cells representing 320 different TPS/RPM combination in a fuel map (X2)? Magic? Please, I don't understand. I've been scratching my head for years.....I guess everyone wants a free lunch. |
