With a advent of Erik Buell racing Buell XB owners have performance oppertunities only available to select racers(picked by HD) before now . The HUGE Dyno/horsepower figures you saw before always where accomplished with a mikuni carb set because the stock Injectors and fuel regulators where too SMALL even if tuned to thier maximum. NOW Erik Buell racing sells the racing fuel regulators and racing injectors to the PUBLIC(the 1125 injectors can be used in XB fabbed)AND at a FRACTION of the cost that they where from HD. So now YOU can get those 130-140 hp at the rear wheel figures ., Andy Simon and I are doing the dyno work/tuning ect and will post ASAP with pics. Cross your fingers you know me and computers lol. Again I do not make a DIME on any of this , I just like helping fellow Buellers . The SHOCK on peoples faces when I tell them My Buell Firebolt is faster on the bottom end than my new Ducati 1198 is priceless lol. They cant say im biased because I own BOTH and the Ducati is the newer of the 2 bikes . Anyway ill keep everyone posted as soon as bikes are done AND look for the new 19row forced air oil cooler THAT is a break through good for any sportbike period a cool engine is a happy engine . Take care Jake | ||

130-140hp at the rear wheel on... I'm assuming an XB12? How does that work? That's significantly more RWHP than the 1125 motor, with a 3500+ RPM lower redline. Or does this process also involve balancing the motor and moving the redline up? | ||
| Froggy |
Syonyk, his bike is nowhere near stock, including some crazy amount of displacement (1700cc?). http://www.badweatherbikers.com/buell/messages/327 77/491683.html?1257943422 | ||
| Greg_e |
1700cc and 729 cams and valve changes might as well work on putting the 1125 motor in an XB. Probably cost less to do the 1125 mod than all the engine work. Now if you get all that with a STOCK motor, we'll be a little more likely to pay close attention. How about with a stock 984 motor? | ||
| Syonyk |
Aaaaaah... ok. Sorry, I misread that as "Swap in the injectors, get 130rwhp on an XB." I didn't realize it was "If the engine is massively modified, the stock injectors can't flow enough fuel." My bad! ... though thanks for the link, that's a truly sick bike.  | ||

Guys sorry for responce delay . Back killing me this week and shop broke a water pipe on sunday flooded the place . Anyhow the Bike a 2007 XB12R Firebolt with the common 88ci kit you can get from various performace dealers (Revolution performance, NHRS, Cycle Rama ect) with stage 3 heads. The BIG dyno numbers with 88ci having 140 RWHP ALL used mikuni 50mm carbs which took a TON of modification and loss of streetability because we (buellers=regular customers) Couldnt get the race injectors and fuel regulators from Buell race dept because HD forbid it unless you ad AMA race licence . NOW with Erik buell racing being formed we ALL can buy race injectors and fuel regulators . the best part is when HD sold the race injectors and fuell regulators the IF you did get them it cost 1200$ minimum ! now your looking at 300$ from ERB his prices are GREAT ( look at the Showa race shock =650$ anywhere else 1000$) This is a PASSION for me. ( health is screwed up, my days are actually numbered =heart) I will be posting pics and REAL lol dyno numbers with my new Ducati 1198 for comparison on SAME dyno. The BIG BORE ( 1700cc-2600cc) machine is a different project altogher. Not something for the average Bueller. Beleive it of not im not a BRAND guy with rose colored glasses on , I just HATE to see a good bike UNDERRATED Buells have a real Race Chassis , just because joe average rider isnt good enough to ride a race chassis he thinks its.. twitchy .. and bad mouths it . THAT irritates me . yes the harely isnt the best engine in the world but that doesnt mean the bike handles poorly . Thats like saying if you put a chevy 350 in a Ferrari it doesnt handle well anymore !! More important is the forced air oil cooler . THAT is good for ALL Firebolts so keep an eye out for it. A COOL engine is a happy engine . After we get the Firebolt cooler done we will design one for th tubers also( I have a 2001 Cyclone and a 2008 1125R) | ||
| Jake318 |
BTW I know its tough to get STRAIT info on Buells . On the internet its so tough because there is American Buells and what parts we could get and EUROPEAN buells which could get MUCH better parts. The average European Bueller could get race injectors, fuel regulators , race headers. intake systems ect ect. So you THINK they are bullshitting when its not (example =Hillbilly motors injected , non turbo bikes . MUCH faster than our bikes ) SO if you want any mor info feel free to PM me and we can talk on the phone , Im a lousey emailer lol. But ask froggy I like helping fellow Buellers | ||
| Jake318 |
FORGOT... The Compression on the 07 1420cc(88ci) bike is 12.5. In ALL performance upgrades ... without compresssion your not going to get the greatest results. Thats why the forced air oil cooler is SO important .(compression makes HEAT) Anouther tip is that the harley AND Rotax engine needs to be balanced, one cylinder inherantly runs stronger than the other. The cylinders FIGHTING one anouther robs power . Dris from TWINS in the netherlands reprogrammed my ECU on my 1125R and it runs significantly better/stronger. | ||

Jake, if you want I can move this to the quickboard so it gets more exposure. This section is intended for announcements from the motor co. and similar published things. | ||
| Jake318 |
Thanks froggy yes please do I thought this would get exposure . You know ive been trying to get people to install coolers and head temp gauges on there bikes. Next its the head temp gauge from dakota digital. I tried the cheaper one from jegs but they dont hold up to vibration . the dakota digital ones do . the dakota gauge cost 135$ BUT then you save 80$ not needing the oil temp gauge in the swingarm which you cant see riding. (xb models) The Dakota head temp gauge you see INSTANTLY you see rear cylinder temp which is the problem cylinder and it looks cool lol. | ||
| Jake318 |
Froggy Im sorry I was the shortbuss kid lol. Could you put this thread in the XB forum? I will rewrite thread in tuber section when we make a forced air cooler for the tubers . This forced air oil cooler works so well if i could afford it I would just GIVE everyone the new cooler on the site . BTW the new forced air cooler was explained to Eri Buell and he DID say ...dam! why didnt we think of that lol. | ||
| Froggy |
Moved to XBoard  | ||
| Livers |
Good luck, and keep an eye on those cylinder studs. | ||
| Hogs |
Interesting tell us more Jake when ya get them numbers etc etc...! | ||
| Brightbuell |
Wow! This is all great news. i dont believe this would all be moving as fast if buell had never been killed. Thanks jake318 for all the info. I will link Buellxb.com to this info. | ||

sounds cool! | ||

I am excited Erik Buell Racing is offering those parts!! What size injectors do they offer? I know you can get 310cc, 370cc, and 450cc/hr injectors from RC engineering: http://rceng.com/Motorcycle-ATV-Watercraft-Snowcra ft-Injectors-C13.aspx?UserID=5639409&SessionID=kQR d4fMGF94sQl1uuu3i The V-rod destroyer injectors are right around 450cc/hr too. All of these will fit with a slight mod to the injector bosses. Here are some pics of my manifold with the V-Rod destroyer injector relief on the left aka rear injector boss:  And here is the V-Rod Destroyer injector on the left and the stock XB injector on the right:  The relief is to clear the injector plug and allow the injector to seat all the way down. As for the fuel pressure reg., Delphi has a 400kpa available which adds about 10psi over stock. Their part number is FP10153. It fits a 1996-97 Dodge Caravan with the 3.8L V6. I am running that FPR on my Buell as well. Here is the outfit I purchased from. They had the best price at the time: carcode,1308822,parttype,6124,d,1996_DODGE_GRAND_C ARAVAN_ES_3.8L_230_cubic_inch_V6_MFI_L_OHV_Fuel_In jection_Pressure_Regulator.html,http://www.rockaut o.com/dbphp/x,carcode,1308822,parttype,6124,d,1996 _DODGE_GRAND_CARAVAN_ES_3.8L_230_cubic_inch_V6_MFI _L_OHV_Fuel_Injection_Pressure_Regulator.html (Message edited by EricZ on July 07, 2010) | ||

Erik/everyone the injectors fuel regulators are on Eric buells racing site http//www.erikbuellracing.com the fuell regulators are 450cfm the injectors just say =racing injectors so erik (the bueller here lol) you will have to call and talk to mike to get specifics .Well im off to shop dam 100+ degree weather makes it dam near impossible to tune correctly. this is why Dris (twins motorcycles in netherlands) air conditions dyno room | ||
| Sneth |
i just bought a ducati as well, and hearing this is making me rethink selling the buell. Would be a fun project bike if things like this keep it going. | ||
| Jake318 |
HELLO ALL GETTING CLOSE!! Even though the shop is Still 100+ Andy Simon has the bike in the 130s(hp) Erik Buell Racing has been involved also and been great, cant say enough good things about them . They Sent ANDY some new maps to try from the XBRR race days and ERIK BUELL even offered to send a bigger race(65MM) throttle body. That was VERY nice of him but I declined WHY? Because I want this project to be something that ANY BUELLER can do EASILY and AFFORDABLY. The 88ci/1420cc kits are readily available, ANDY or BC-GEROLOMY bores the stock throttle body to 50.5mm Andy is writing down and loging all the maps , and hes making the forced air oil cooler keeps the whole engine very COOL AND A COOL ENGINE IS A RELIABLE HAPPY ENGINE . WE are NOT making a RACE bike . This is a high performance 1420cc Firebolt with hp in the 130-140 range thats reliable/STREETABLE. Yet has more BOTTOM end power than my Ducati 1198 . The 2001 Cyclone ANDY and I did earlier has all Bolt on parts and It did 102hp and 98lbs torque which is great for a tuber ( Andy is in the RECORD/HISTORY books for his woRk with those harley heads /motors thats how I found him Brian NALLIN said he was a living legend =Andy would kill me if he read this lol) These numbers are Hp at the rear wheel btw . I MAKE ABSOLUTLY NOTHING AT THIS ITS JUST A PASSION!! I WANTED MY FIREBOLT TO HAVE MORE BOTTOM END DRIVE THAN JAP/EURO SPORTBIKES. I knew it could be done because you get the power/torque at such low rpm where as the jap/euro bikes have to wait till high rpm for power. I KNOW they will pass me down a LONG strait but having a sweet handling bike that drives off the corners like a rocket is the best feeling in the World !!! BUT THEN AGAIN YOU ARE BUELLERS ALSO, SO YOU ALREADY KNOW THIS LOLOLOL (Message edited by jake318 on July 10, 2010) (Message edited by jake318 on July 10, 2010) | ||

PS I do love my Ducati 1198 ...Just not as much as my worked Firebolt !! | ||
| Gunut75 |
Ahhh...... theres no replacement for displacement......neato! | ||
| Greg_e |
You keep mentioning this forced air oil cooler, do you have a link to this or pictures or something? How many rows of tubes does it have and does it have a much larger area than stock (longer tubes). | ||
| Sticks |
Yes, we want pretty pretty pictures of the cooler. | ||
| Rsh |
I believe he is referring to this one from Twin Motorcycles. It is a 19 row cooler, with a ram air duct.  | ||
| Jake318 |
VERY GOOD .. BUT >>> you HAVE to have a second scoop to force the air through the oil cooler the air is taking the ath of LEAST RESISTANCE and passing BY the oil cooler and going to the rear cylinder. But thanks for pulling up the pick . I tried to pull that pic up before to no avail. RSH/STICKS do you see how it wont go through cooler. ( except by venturi effect but thats a minimal amount) Once you have second scoop the ventri effect does help as the scoop is pushing air through the front of oil cooler and the venturi effect is pulling air through cooler from behind | ||
| Rsh |
The original Hals XB Formula Extreme race bikes used a oil cooler setup similar to Twin Motorcycles.  The XBRR oil cooler is rotated to take advantage of airflow at the slight expense of added width.  The XBRR fairing has a slot to feed air to the oil cooler.  I totally applaud your effort to build a high performing XB in an effort to surprise the everyday GSXR,CBRR,R1 and ZX10R rider and give them something to scratch their heads about. I think it would be more beneficial and fun to turn your 1125 into a 1190 for the street and really show people what time it is. (Message edited by rsh on July 11, 2010) | ||
| Jake318 |
RSH the XBRR oil cooler set up wasnt as good as the TWINs and about 1/10 as efficient as our NEW forced air oil cooler. Erik must have putting moves on the umbrella girls the day he did that lol. For one , the slot was OO small to build enough pressure and Secondly the oil cooler stood vertical with about 6 inches of free space to the right. The air just went AROUND IT . RSH I also have a 20009 1125R with German HPE race exhaust , intake and race ECU . tuning by DRIS in Netherlands. With a XB1420cc giving 135HP115 torque at ONLY 2500/3000RPM it Is faster off the bottom end/ more accelleration/ drive off corners than a WORKED 1125r and even the 185hp /100LBS torque 1190RR . WHY?? the 1125R AND 1190RR use over square combustion configurations ( bigger bore than stroke) and delelope power at 10,000/11,000 RPM . YES its more efficiant and YES and oversquare high RPM engine produces more HP..but .. you have to WAIT for engine to get to those RPMs. The XB engine is UNDERSQUARE = Bore is SMALLER than stroke. ITS less efficiant , produces LESS HP but MORE torque . BUT>>>> you get your HP at LOW RPM = right away/instanly . the 1190RR having more HP eventually will Catch up and Pass the XB 1420CC firebolt on a LONG strait away .

RSH/everyone ... ERIK BUELL COULD HAVE MADE THIS SAME SET UP AND BEEN ON ALL THE COVERS OF CYCLE WORLD. why didnt he? the epa !! THE XB IS AN ancient low tech engine . IT NEEDS BIG CAMS, BIG DISPLACEMENT, BIG THROTTLE BODYS/INJECTORS/EXHAUST TO ANYWHERE near COMPETITIVE. so it would never pass the TREE HUGGERS REGULATIONS | ||

>>>>so it would never pass the TREE HUGGERS REGULATIONS Name one race only motorcycle that does. By the way . . the XBRR was on the cover of Cycle World. |
