in this "quiet" period would be good , interesting and appreciated all of you Racers showing your bikes and spending some words about mods upgrades and technic experiences engine , gearing , suspension set-up exct. exct. .....just an idea , just curious ( sorry...not a lot of Buell racers here to speak with). to Buelldyno-guy Thank you , sincerely , the upgrade you told me about the pump seems to work fine. give you a pic. bye Alessio  | ||

I did a bulk of my planned work last winter, but this year I will be adding a new rear shock, an 1125R fairing and stay, a Starline Athon lap timer, and rework a couple of other things. I don't have a digital camera right now, but I will post some pics when I can. | ||

Eboos, I ran an 112R fairing all last season without switching to that stay. The 1125R fairing will bolt to the lower XB-R stay boltholes and with a very simple flat piece of sheet metal on each side, the top bolts right up. I'll try to get a photo up in a day or two or pm me. Now I'm just waiting for Zero Gravity to release their new double bubble windscreen. | ||
| Eboos |
I am a little more retarded. I am adding this to my M2. I got tired of kissing my gauges in a tuck all last year, and the protection will help. All and all, this is pretty cheap for me since Airtech kind of owed me after last years bodywork fiasco. | ||

Added a Penske before my second race on my Buell, final of the season, in September. Wondering if I should consider going with a heavier spring or two for my inventory. Buell springs up front. Was using 15wt oil as whatever came in it just had no dampening for me at all. Swapping to the chain conversion with swingarm. If anyone is looking for a chain kit with the manual adjuster, PM me please. Gonna tear apart an extra wiring harness ans strip it down to nothing along with looking for any weight I can get rid of on the bike, and me. Need to tear down the motor. I really don't have a fourth gear. Shift drum seems to be the culprit. I have a race tail on the way, and I'd like to replace my Hal's full upper and lower with head light cut outs for a proper full race upper. Sourced a lower on line a couple months back, and I think it's Yoyodyne, so I'm looking at selling the Hal's street bits to buy the upper from Yoyodyne. I have a Yamaha/Brembo master cylinder to install. Might go with the ZTL2 caliper. And I need to install a slipper clutch. And, and, and...LOL! Daytona is feeling too close. Not sure if I'm going, but I think I need to plan toward it. | ||

Gearhead i read on your profile your race xb is a 04 like mine so maybe you have already done the fuel pump mod or you swapped with the new one , if not think about it . it will save you from some really bad situation . it is doable and costs just the price of the new o-rings. bye Alessio | ||

"Was using 15wt oil as whatever came in it just had no dampening for me at all." I had the same problem after I rebuilt my forks. I used 5wt oil as recommended by racetech. I had GMD computrack redo them after that. I am not sure of the oil weight, but everything's good to go. I have mixed feelings on stripping my wiring harness. This bike will likely never see the street again, but I am not sure I will see much of a weight savings for the effort. Have any of you dropped the starter motor? This was a weight savings idea that I have been toying with. Oh, I just realized who you were SD26. You're SuperDave from CCSforum. Welcome to Badweb.

hey dave, i've a buell upper fairing number plate that fits right over the headlights if your interested. already painted yellow,if your an amateur. i run a ZTL2 on my racebike with a gsxr m/c i got of ebay for $40,works great. | ||
| Eboos |
He will need to paint it white.  | ||
| Babyhuey |
that's what i like to hear! i'm gonna have to paint my plate white too.  | ||

Alessio66xb12r, I am very interested in your fuel pump mod! I've had fuel starvation problems heading out of turn 5 at Road America, I understand. I'm planning on removing mine very soon after reading about your mod, I may be in touch as I know what an '06-'07 pump costs!! | ||
| Alessio66xb12r |
chain conversion with SWINGARMi really miss it sometimes change of rear sprockets is a drama . i ended up with two chain and 2 different adjuster just to use the 4 sprockets from 47 to 50 of my Freespirits kit. another drama : mod a WP rear shock due the use of the long ss swingarm 40 cm inter-axle its what needed ( +/- 1 cm adjusting)  i found the longer swingarm better for track use. not sure , i think short frame and long swingarm is similar to the xbrr quotes. bye Alessio | ||
| Skinstains |
What "mod" is there for the fuell pumps ? | ||
| Alessio66xb12r |
Gearhead don't know about a new fuel pump cost , for sure here the cost is crazy , for me it does'nt make sense because the new pump has the same fuel pressure and all you need are a couple of small tubes . for what i found out the only difference with the new style configuration is a tube that directs fuel from pressure regulator housing to the fuel screen. (to be honest) i think is an Henry Duga mod told me by Terry P. . very happy of this mod , it was a Big problem ....and dangerous. feel free to ask if in need , i'll be happy to give you all info and pics . bye Alessio | ||
| Alessio66xb12r |
Skinsaint read the "engine turns off" thread here a couple of days ago bye Alessio i'm sure all the 04 and earlier models race bike owners are interested in this | ||

Hey, Eric. You got it. I'm incognito...LOL! Yeah, I've had a white plate for "a year or two"...  ...or twenty. I picked up a second harness to do the strip. I'm in the same boat. Maybe it becomes a street bike, maybe not. But if I leave the stock harness stock, it's certainly better than cutting up one and having no back up. I don't see much weight being saved, but with it all coming down, I might as well go for it. I haven't really taken the time to building a better race bike in some time, and the Buell needs a little work for the task and goals, so I need these little bits. It's an investment of time. I like the idea of the headlight cover, but I have that extra lower, I might as well go for a proper upper. And the full Hal's thing should finance that, I hope. Andrew, how do you like the ZTL2? What made you change? I was thinking that I was gonna get a little better life out of pads from the ZTL, but I was wrong. And the timing was bad too (during a race) when it went to mush. What's the general take on the life on the eight piston vs the six piston? Braking performance? I guess after I raced the second weekend, I'm thinking that maybe my braking performance wasn't as good as I felt it should be for the effort that I was putting into the effort. Eric, I've got one of the Starlane lap timers, and I've got some data from my Buell and from my GSXR, so I'm going to look at that one of these days and compare. I think maybe once the geometry is all messed up with the longer chain drive swingarm, maybe I'll get some different weight transfer, some better lap times and all that stuff. | ||

dave, the only reason i switch was my pads were worn out, so instead of just replacing the pads i got a whole caliper loaded ready to go. it seemed like the logical time to up grade. i didn't have any problem with the old one since i changed my riding style. i used to burn thru pads at trackdays until i changed how i use the brakes. when i first started trackdays i would be so hard on the brakes that the rotor would great cooked and the pads would crystalize. now i use alot less brake, i brake earlier and lighter, carrying alot more entry speed into the corners. most corners i can get away with using almost no brakes and just engine braking. i can make alot of time with corners speed(its really fun)and be alot smoother. as far as the liking the ztl2, if i need the stopping power its there,no doubt about. i had a panic stop a couple of races ago and popped the rear wheel up into a corner,not a big deal normally but it got about a foot up. so by the time i got it down i was way to deep. i wouldn't change anything tho .-andrew | ||
| What_the |
gear this may help...... XBRR fuel pump anti cavitation cover. P0304.07AH | ||
| Gearhead |
What_the, Thanks for the heads up on the XBRR part. I'm going to stop out to the dealership this afternoon so I'll check on the availability of this part. Hopefully, they'll have a photo to help me figure out how I can utilize it. Thanks again! My teammate, Troy Walbaum, CCS Amateur #173, just spoke to Henry the other day and he recommended replacing the valve springs after every season with stock springs. It makes sence to me and since I've never had my engine apart it's now on my to do list, also! | ||
| Gearhead |
I checked the XBRR catalog for the XBRR fuel pump anti cavitation cover, P0304.07AH but there are no photos of this part or the fuel pump. My dealer couldn't find it in their computer so it must be a Henry part. "What_the" can you shed a little more light on this part or have any photos? If the RR's have an improved part and it's affordable, I'm in. Thanks in advance! | ||

Eric, Rather than dropping the starter [which will then require the use of a starter cart - something of a PIA] consider losing the charging system and stock battery in favor of a small NiCad battery running constant loss and a on-board jack to plug a starter battery in. Much more in the way of weight savings and less parasitic drag on the motor as well. Worked well on my S1 racebike. Contact Robert Johnson at J.E.T. for how-to. | ||
| Ceejay |
couldn't you just bump-start? Mine's turning into a track only bike after a recent bumper test and that's what I was thinking of doing. Run a small battery to account for over/underloads and just throw her in third and go for a little jog... | ||
| Slaughter |
Having been around these bikes with failed starters NEEDING to be bumped, I'd STRONGLY recommend that you just remove the rotor/stator but KEEP the starter and battery. Yeah, they're not very light but they make life so much more livable. Really the ONLY way to go racing without a starter motor is to have the starter/start cart or starting rollers in the pits and keep the bumpy or second start cart down by the track entrance... more trouble than its worth. The FIRST TIME you have to shut the engine off for a delayed start, you will be cursing life... and the FIRST TIME you stall the engine - same thing. NOT FUN | ||
| Xoptimizedrsx |
on the fuel pumps can minuplapating the duty cycle help you guys. as i can give you the codes to rearange it in time or just shut off the cycle look up. this is for all buell bikes even the 1125r. ecmspy will do it to all buell any year. as well as the delay timer resetting to apply the open loop correction % applied. and wot fuel % mike | ||
| Alessio66xb12r |
to Xoptimizedrsx i asked about the "duty cycle" few days ago...what is the duty cycle and how can we work on it using ecmspy the codes to rearange it or just shut off the cycle look up.....that means ??? let me understand please , i have a vague idea not enough to play with it. thank you in advance bye Alessio | ||
| Sd26 |
Let me see if I can point him your way. Do you have his email address? | ||
| Xoptimizedrsx |
sent pm. what ecm i can tell you the locations to either make it 100% at all times or scale it to 100 later. you will also want to scale the temp fuel correction to 100 at all times for safty. its at 97 % up top. i change mine to add more as heat get extreme. you need it as a coolant. even though the afr goes down heat will kill it if you get a oil issue. it just may make you finish a few needed laps and finish. with out the dnf on the score chart. finishing last is better than not finishing at all. if you chase points. log into the pm and post in my area in racing. i'll tell you there the codes. | ||
| Alessio66xb12r |
thank you S.Dave and Xopti | ||

There are some of us that with the use of the Kimbal DOS Program have seen the inside of the Henry Duga Buell Race Only ECM. I believe you can't do that without developing a respect for the Buell Engineers that developed them for both race and street. I have tuned the Henry's Race Only units as well as re-tuned Buell Stock units using both Direct Link and ECM Spy. So I caution anyone willing to listen, just because there are programs that let you make changes, does not mean it's the right thing to do. If you are on the track only then you may have more latitude in what you can get away with. I have built and tuned XBs with big motors making 126 RWHP and yes we bumped the fuel pressure for wide open throttle, but again that was with a replacement part from Henry. Never had any reason to change the temp offset or pump duty cycle. And BTW this bike runs on the street all the time and the AFV is always at 100% +- 5. There are things inside these ECMs (algorithms) that without engine test cell data are best left to those who developed them. I know if I spend 10 - 20 hours of dyno time developing a special map there is a reason the look-up tables have certain values and yes you can go in and change them but your at your own risk to do so. I have shared some of what we have learned with several racers here on this board, but we do that with the idea no one has gone and changed some of the constants. I have developed maps for both 380 and 450 kPa fuel pressure regulators, and would have no idea what they would do if the duty cycle of the pump had been revised. ... Just my humble opinion and hope it helps someone. ... Terry JT&S Performance | ||

i do believe all the guys are looking for is the constant to become fixed. i have ran test myself on a few bikes with it set constant and variable. the o2 does change as well as pattern on the cells. you can see it apply fuel differently. i like mine constant. then it easer to adjust the fuel maps for me. i also like the multiplyer to be live for the track and one second on the street. as we set the lfuel(AFV) table fuel to a 100 afv fueling. then apply the open loop zone a respected fuel. using the tps acceleration enrichment and open loop enrichment values to adjust the fuel for power yet setting the fuel table all to blend the maximum afr for the bikes power. done correct you get great power in open loop with economy miles(laps) then the wot is set for max afr needed. yes its tricky at first but once you get the calculator out and figure out how each area works together at once its not bad at all getting the ecm to become powerful and smooth. there is a few ways to do it. if you are moving everything at once and not sure set it back to factory. then do one area at a time and watch how it reacts on the 4 gas and dyno. create info sheets then over time it will click. i dont know the dos system at all. i do know cells you dont see in ecmspy but can change in hex code if you know the values meanings. just do it carefully sometimes less is more. the lfuel(afv) needs to run a 100 +-5 maxium. i prefer a 99.0 to 101.00. then its sweet. those on the 1125r bikes and a afr of 100 is not uncommon on the last update. the multiplier set it to 110% and duty cycle set to constant it makes a great improvement. yes ecmspy will update this . already road tested it and the afv (l_fuel is not corrected) still the same every time. every test. thanks for the post terry!!!! nice to get good incite on other tuners with time on there belts. mike | ||

Good point slaughter and one I hadn't thought of too much...I rarely puke my bike, but the thought of running down pit lane seems silly... |
