Bonneville August 2010 BuB speed record attempt
2-9-2010 - updated 28-08-2010. We will try to set a speedrecord with 3 Buells in August 2010. Because it is speed, what we need (-:
BuB only runs motorcycles and they're under AMA and FIM rules.
Twin Motorcycles will be closed from the 20th of August till the 12th of September to try to set a speedrecord attempt. http://www.speedtrialsbybub.com/2010_event/index-2010.html We will do this together with Glendale Harley Davidson in California USA. In the first week from the 20th of August Dris will dyno 3 Buell Motorcycles at Glendales. 
1. Buell XBRR (special engine build). The XBRR is running in the APS-PF 1350cc class APS-PF is special construction partial streamline pushrod engine fuel. 2. Big bore XB9 (special engine build). The XB9 is running in the APS-PF 1000cc class 3. 1125R (special cams and pistons). The 1125R is running in the AG 1350 class.....special construction / gas. All 3 Buells will go for a speed record attempt in a different class. Pictures of the XBRR. The XBRR is running in the APS-PF 1350cc class, APS-PF is special construction partial streamline pushrod engine fuel. 
2. Pictures of the Big bore XB9. The XB9 is running in the APS-PF 1000cc class. 
3. Pictures of the Buell 1125R. The 1125R is running in the AG 1350 class.....special construction / gas. 
All engines are a special build by Glendale HD for speed purpose and Twin Motorcycles will make the fuel maps for it and help with the maintenance at the Speedweek. We will fine-tune the bikes at the salts to see what speed we can achieve. Enthusiastic Buell riders are welcome. Because this is our first Bonneville experience, we know we have a lot to learn, but if you don't try, you won't succeed (-: I just finished testing stuff for the 1125R for Bonneville, these parts will also become available for street use. The stacks will be available at the end of September. They were made by my friend Pasi from Finland. The 1125R has special pistons and cams, that will become available also later this year. I just finished intensive testing for the intake stacks on a 2009 1125 CR Buell. 
In the graph below, you see a 1125CR 2009 model with a Jardine slip-on, K&N airfilter and our tune: It makes 139.4 HP and 110 NM of Torque, this was a difficult exhaust to tune right. 
Because we tested 4 different intake lengths, I only will show the longest and the final version. Important are the following notes. Same bike, same day, same gasoline, same dyno tuner, same engine temperature. Below is a graph with the longest stack we developed, it made 134.4 HP and 113NM of Torque. So we lost about 5 HP and gained 3 NM of Torque. 
Then we opened up the air box with the K&N filter, left the K&N filter in place and made a run with a open air box. The results were: 137.1 HP and 117 NM, so we gained 2.7 HP and 7 NM of Torque. Look below: 
Then the final version. It made 139.9 HP and 114 NM of Torque. So we gained 0.5 HP and 4 NM of Torque, look at the results down in the graph, compared with stock tune. 
Then we tested the final version with a open airbox and also left the K&N filter in place, only took the cover and inside cover off. The results were 141.6 HP and 115 NM of Torque. So we gained 2.2 HP and 5 NM of Torque, look down for results. 
Below is a result with the longest stack we tested and with the final version in a open air box situation. 
After all the dyno testing, we made a final choice for the stack height and take them in production. We will also use these at Bonneville, because we need a lot of HP and Top Speed. For people ,who race, this is real cheap Top end HP and Torque. They will be available in September as part in our shop exclusively. update 12-8-2010 Stack's for Bonneville are ready and for sale. http://www.twinmotorcycles.nl/webshop/artikel.asp?guid=YXHFSC&aid=3005&cid=0&s=stacks&a= 
Update 22-08-2010 After a long flight with KLM, we arrived in beautiful California. Picked up our rental car and drove off to Glendale HD to meet up with Don. 
It is really nice over here. We started with getting everything working for the dyno the way we liked it. The Buell XB9R was already on the dyno, so we started checking stuff and started dynoing the XB9R first. 
We first needed to get the Dynojet dyno running properly with 2 wide band sensors. So Dris started tuning and we started to do the last preparation for the Buell 1125R and the Buell XBRR, before we put them on the dyno. 
And it is always (see picture below) nice to see our own developed products in a world record speed attempt. 
After some testing and different dyno runs, we decided that we take the XB9R off the dyno to change some things. As you can see below we have long and busy days with friends wrenching. I am lucky Martin is also here to take care of everything besides dynoing, Martin thanks for that (-: 
So the 2008 Buell 1125R was ready and we put her on the Dyno. After some runs and getting Idle and a lot of other stuff right, I made the first WOT run and gained 155 rear wheel horse power SAE corrected on the Dynojet Dyno and there is still room for some more :-) More to come, stay tuned. Update 22-8-2010 Okay, I finished tuning the 1125R 2008 model today, with our pistons, cams, intake stacks and Fuelmap. It makes on a Dynojet Dyno in de USA SAE corrected 161 HP and 92 ft/lb (125 NM of Torque). Look down for the graph. THIS IS DONE WITH STOCK HEADS AND STOCK CYLINDERS. WE STILL NEED TO MAKE A 1190 KIT AND DO THE HEADS (-: FUNNY HOW THINGS GO IN LIVE. 
The problem was that the Dynojet Dyno has a limit of 222 Mile per hour, it braked and all red lights in the screen hahahahahaha, that is 357 km per hour. Shitty Dyno that Dynojet Dyno (-: I make that in 4th gear, so we were not able to see how much top speed the bike could make. Oh, well that's what the people at Bonneville will measure for us. Update 24-08-2010 XB9R update. Because of some engine noise, we decided to pull her engine apart. Good thing that we did, the crank had some small connecting rod play, and the valves already hit the pistons. 
Okay, where to find some rods and bearings.. Luckily we had a little help from the crank wizard of SOCAL, who brought us a new one. Thanks Will. The XB9R engine was closed again and the bike rebuild, and now she is ready again for Dris to do his magic on the dyno. 
When we pushed the 1125R back from the dyno to the work shop, I noticed there was something dragging.. first thought brakes sticking or rear wheel bearings where gone .. Nope the 1125R did chew her transmission , Damn… Don made some calls and luckily Buell Racing still had some transmissions in stock, should be here today. Thanks Michael. Todays job would be pulling out the 1125R engine and taking it apart.. 
XBRR ready for the dyno Update 24-8-2010 We got the XB9R fired up again after replacing the engine and checked everything twice and she runs way better now and gave her to Dris to complete the tuning. I pulled out the 1125R motor and completely took it apart to find the binding gear. 
Box of goodies from Erik Buell Racing Mainshaft and the suspected 5th gear looked okay, the 5th gear was still the old type so it was a good thing we opened up the engine and we replaced it anyway. 
Engine out and on the work bench We did find a piece of plastic that was being chewed trough the gears, we still are puzzeling were that piece was coming from and how it ended up in the engine, all shields, guards, guides and plastic gears were okay. 
The above plastic pieces were binding the mainshaft We're putting the 1125R engine back together, everything looked fine. This baby is going to scream on the salt. 
Cases ready for the crank to go in 
Very heavy duty connecting rods and bolts. The XB9R is almost ready on the dyno. we achieved 88 HP and 68 ft/lb not bad for 1000 CC.
We were able to let her make 180 miles per hour. So hopefully she will be able to run fast enough. Update 26-08-2010 Okay the XBRR is ready voor Bonneville, I achieved 147. 45 HP and 140.36 NM of Torque SAE corrected. 
And the XB9R is ready: 88.44 HP and 92.80 NM of Torque SAE corrected. 
Be aware that this is 1000 CC. We have no time otherwise we would be able to let her make more power. We are packing all our stuff and go to sleep. Tomorrow morning early we leave for Bonneville. It is possible that there is no news a few days. Stay tuned I update through Facebook and Twitter. On our homepage you can find the links: Twin Motorcycles Update 28-08-2010 After a hot and long 16 hours drive through some very nice spots in California and Nevada, we arrived. 
On the road 
Nevada long roads 
We reached the Salt, the first views are breathtaking, incredible how far you can see and there is a whole lot of nothing there. 
We got our pit area up. We needed tents to stay in the shade and don’t overcook ourselves. 
A lot off sun overhere Did our last checks to the bike and run the bikes up for registration and technical inspection, which they passed without any problem. 
Waiting game for tech The salt conditions are good, still a little wet, but the wind picked up in the afternoon and this will help the Salt to dry really fast. 
Tomorrow morning the speed trails will start and the waiting game will start. 
Did I tell you it's hot out here? 300 riders will start with the short “5 mile mountain course”. After the first run the fast bikes will go to the long course, we need to let 2 riders pass for the test (fingers crossed). Rachel, being the rookie, first has to go trough the briefing and run over the track to see where she is going and get a better feeling and understanding. Because the Salt Lake is so big you really get disorientated and you can get lost there. So a test run over the track to get a good focus point where to aim for while driving, is very helpfull. Tomorrow more news and pictures. Update 29-08-2010 The salt is really more difficult than we first thought. Our dragrace and road race experience will help us to understand this, but we have a lot to learn. After 1 day at the Salts, we focused on the XB9R and the XBRR. We have the XB9R stable and our driver (girl) Rachel is getting stable. 
Mug shot from the drivers Rachel did her first run 125 miles per hour, her first run ever on the Salt (Mind you, she did get her motorcycle drivers license only last December !). Second run was 141 miles per hour and getting more stable. The 141 was enough for a record, so we made the return run. We had a very bad wind 14 MPH in the front. 
Rachel on her 141 mph run She was leaning all the way to get the bike straight and still went 133 miles per hour. Way the go Rachel! The record is set at 137 miles per hour. What happens is, that the average the 2 times from the front and return run and that is the average record time. 
Camouflage leathers Richard is driving the XBRR. He is a experienced Salt driver with 5 years Salt experience. 
Richard back from his first run His first run was already a record time. 166 miles per hour, the old record was 165 miles per hour. 
After a record run the engine has to be sealed by the tech's He was learning how the bike was going, not bad at all. His second run, he did 168 miles per hour. The current record is set at 167 miles per hour. There is still speed, RPM and potential in the XBRR. 
Rachel prepping for the second run We are now focused on the 1125R. The swing arm was lengthened a lot and that made the bike very instable and impossible to open the throttle. It was spinning the whole bike to the left and rear. Yesterday evening we took the weight off the bike, brought the rear wheel back to his original position and started all over again. Just to see how it handles the power. 
Debriefing by Andi 
Don prepping the 1125R to get more stable 
The Buell Brothers and Sisters pit 
The XBRR from NRHS Update 29-08-2010 Tonight in our hotel we heard it rain very hard and the one thing you don’t want, is rain. We were not permitted to the salt flats, because there was too much water on the salt. 
Wet spots on the salt After 10.00 in the morning, we could get to our pits and we started working on our bikes , it dried up good and fast. We fitted the data logging system on our Buell XB9R and gave a little run over, we could hear that she was running rich, but we needed to analyze the data to see how much we needed to adjust the fuel. 
Bikes lined up in pre stage On the 1125R we changed a lot. We have an unexperienced driver and a very difficult and hard to handle bike with a lot of power. We shortened the wheelbase back to the original length and for the first time set the suspension up. We started playing with the tire pressure and asked the driver to take her for a spin, just to check if we were going the right way, get more stability in the bike. It felt a lot better right away. So with all the changes we were on the right track. We made some more changes and now he felt he could launch the bike for the first time. The track dried out good and runs were started at 15.00. Both Rachel and Andi were lined up. 
Line up at the 3 mile marker on the long course And both made their first run of the day on the long course starting at the 3 mile marker. Rachel did very good again and made an 141.6 mph run, faster than she ever did go. Andi shake down run felt also very good, bike handled so much better, only the speed was not what we expected it to be. Rachel did not get the back time she needed for her run. So no upgrade for her personal record yet, but the Buell XB9R has the potential to go much faster. 
Rachel ready to start 
Andi at the starting point We checked the bikes and lined them up for their second run of the day, but we ran out of time and the track was closed for the day. 
Early mornings at the salt The weather conditions for tomorrow looked promissing, the XB9R and the 1125R are lined up as first to go, to get some runs today.  Rachel on speed Update 30-08-2010 Very early 05.30, we went out to the salt flats. Rachel and Andi are the first to line up. So the pit was set up and drivers got themselves ready to go out, we checked the bikes and the data logger was mounted on the XB9R, so Dris could check the changes he made to the fueling. 
Our little record breaker, we're proud of her We programmed the 3 bikes for this altitude, but a little on the save side, because we had no experience with the salt, the fuel, the conditions with the humidity and barometric pressure. The 3 bikes were running a little rich, but better that than way too lean. Understanding the conditions on the Salt Flats is not an easy thing to do. You need to spend a lot of time to understand what’s happening. 
Andi back from his run We tried to let Rachel shift a little lower in the rpm range, just to see if that would give her some more speed and if the bikes was able to do that with the gearing. That did not work very well, because she shifted back to 4th gear to keep the power up. The gearing choice was maybe not the right one. Andi finally got some speed in the 1125. That bike is a real mean bitch to ride, so much power to get to the salt and the rear wheel slips about all the time and when really giving full throttle, it feels like a rolling burn out all the way. 140 mph was all he could get out of it. We started experimenting to get more grip on the rear wheel, we dropped the gearing down to make the bike pull a little less hard, lowered the rear tire pressure even more, looked again to the suspension. After everything was done, both riders lined up for their second run of the day , this was going to be a long wait. Richard took the XBRR out to see if we could improve the record a little more than he did the day before. 
Richard was flying again to just get a little more The first run was 171 mph… that bike is flying with wheel spin all the way. We went back to impound, to let the technical people inspect the bike and get their approval for the return run. To make it an official record nothing on the bike is allowed to be changed, only fuel and repairs can be done under supervision by a technical inspector. He was ready to go to the line up at the other end of the track for the return run. He was able to do that with an 167mph run. That was all he could push out of that bike with a lot of wheel spin in all gears. We were going to try and make some changes to see if the bike would run any faster. The biggest problem was to keep the power on the salts. The bike makes power enough. 
After being cooked at the starting line for 4 hours the drivers needed some shade and relaxing. Looking at the starting line, it would take them 3 to 4 hours, before they could have a next try. We decided to call it a day and prepared the bikes for tomorrow. We took the bikes to a car wash area to get all the salt off, nasty stuff this salt. It is really getting in everywhere, in the most impossible places.
