i was wondering what anyone has done to get a lil more oomph out of their XB. personally i have done the usual (full race kit, pro series plugs, synthetic oil...ok ok not really a performance upgrade) on my 04 XB12R. since i had my top end torn apart (rusted cylinder and busticated rockers) i had a 5 angle valve job done along with porting and polishing. now im down to the expensive stuff. American Sport Bike as a "race tuner" available, Red Shift has cams, and Zippers and Nalin have big bore kits available. has anyone tried any of these parts and if so what did ya think? lemmie know. | ||

If you cannot enjoy the power of your xb12 with minor mods, naybe you should sell it and buy a GXR1000 or something that will have more power than you can use. | ||

There's lots of goodies to be had as far as performance.....try the sponsors section. | ||
| Kowpow225 |
Oh...how did your cylinder get rusted? | ||
| Unbuellievable |
holling! how dare you deface this message board with your gsxr smut! haha! anywho, im not interested in rice rockets at all. i'm a gear head just looking for advice from others. 150 hp gixxer isn't all that impressive. 120 hp 100 tq xb12r...now that's something to talk about! and thanks kowpow for the advice, but i'm looking for thoughts from people who have TRIED the parts available.  | ||

oh and to answer your question...i have no idea how the rust got there, its definitely not from a lack of riding. logically nothing makes that much sense so im gonna go with factory flaw, probably not the answer but thats all i have. plus factory warranty covered it, so no money out of my pocket muahahaha! | ||

I'll bet if you contact Revolution Performance, Cycle Rama or NRHS and ask if they have any customers you could talk to who have done XB mods and how well they like it, they'll be happy to supply some references.

I'm happy with the 1250 mods that Hal's did on my 03 XB9R. I'm sure with some tweaking and hotter cams there is more power than the current 99.6 rwhp and 86 ftlbs of torque. I think keeping it "mild" will help to keep it from dying pre-maturely. If you take it to the ragged edge expect the motors life span to be significantly shorter than stock, but that is true of any engine. A stock XB12 with an open air box, and drummer ss, or Micron serpent with direct link tuning will produce 100 hp these days. | ||

Diablobrian, Has there been made a direct link map with the drummer ss and open airbox for the xb12? (Message edited by riclyd on November 06, 2006) | ||

try 180 hp on a gsxr not 150 well the 1100 any way and its for sure impressive i love my xb12 no doubt but not even in the same catagory | ||
| Unbuellievable |
ok this is my argument pounder...150 or 180 hp gsxr is well pretty zzzzzz. they are a dime a dozen and every 16-24 year old has one. don't get me wrong that's great and all, but doesn't make my pants feel tight. nothing gets my blood boiling more than a strong v-twin at full throttle. it's not that i'm unhappy with my bike cuz i love it to death! i'm just a grease monkey that wants more. i'm sorry but getting more power is my crack. i'll always want more. is it really all that much of a bad thing? and i have read everything that nalin had to offer about their kits. i've noticed most companies are using the components. but if i call them and say, "tell me how good your kits are," that's exactly what they are going to tell me. i think ill save the long distance money. that's why i brought up the question. so if ya have done anything let me know. AND TELLING ME TO GO BUY A GSXR OR SOME OTHER OTHER RICE BURNING SCHINANIGANS IS NOT GOOD ADVICE!!! IS JUST PLAIN BLASPHEMY!!! i love my john deere technology and i plan to stick with it. haha. oh and thanks for the advice diablobrian. | ||

Talk to Al at American Sport Bike. He and Terry P (Buelldyno_guy) have been developing maps. DaveS at Appleton has also been working on maps so the database should be growing. The XB12 with open airbox with the Micron has a lot more development, but they were supposed to be doing a map for the DrummerSS in both places, so I'm not sure if either shop has a map they are happy enough with to release. | ||

I recently saw and talked to the owner of an S1 with a big-bore kit. I asked him the usual questions... More vibration, MUCH more power, less mpg, ran a little bit hotter, more snap to the exhaust note... He already had the upgraded exhaust, airbox, etc... Can't compare the ignition though... What he told me is the same opinion I have when I bore & stroke an HD motor. A little less drive-ability at lower rpms, then arm-pullin' power all the way to red-line! If your lookin' for power, go big-bore. Then you can add nitrous later! | ||

I have a 1250 with Nallin heads and to be honest I dont think it feels any differance vibration wise than a stocker. I beleive it runs cooler because of Nikasil cylinders and a much more efficient exhaust. I gave up no driveability. It has stock cams, air box and filter and a Drummer SS and couldnt be any funner to ride. | ||

Thomas... Did ya have to go with a Direct Link tune or just your Buell Race ecm I see you had a xb12 before hand.. So you just went for the extra 50 cc`s instead of the 1450 kit, Thats where I think the mods stop until someone can figure out the ECM for the BIG bores...! | ||
| Fullpower |
Thomas L: do you happen to know your compression ratio? did you bolt up the nikasil cylinders yourself? what are your octane requirements? does it behave itself running pump gas? do you notice the nikasil cylinders warm up faster than the iron barrels? Lastly, are you running a custom map, or just a out of the box race ecm? I know, a lot of questions, sorry...... Thanks for the report. Dean | ||

I really dont remember why I didnt go for the 1450. I did use 30 dome pistons and had the chambers cut for them.I did some additional port work and chamber work also. I tuned it with a Innovate LM 1 and a DFI the best I could. I want to have somebody tune it on a dyno and a direct link but around here and with my schedule it just isnt gonna happen. I wasnt interested in building a racer just something torqueier and no maint. | ||
| Thomas_lindemann |
compression is 10.5 I did polish and I mean polish the domes and chambers. I set the deck up at .040" Yes I built the motor myself Nallin did the heads and I did some additional work to them.I run 93 octane in it and havent had any problems yet. The Nickasil cylinders I dont think get hot any faster but I know they run cooler I personaly think it runs cooler than a stocker even with an additional 50cc and some more compression. Tuning it for WFO is simple but its the part throttle thats a pain. I have tuned a Hayabusa with a data logger also and it takes forever for part throttle to be right. I put a chain conversion on it simply because I needed to get rid of some gear on it it always feels like you need to put it into 6th. | ||
| Hogs |
Hey Tmomas, Mind IF I email ya and ask ya about the Innovate LM 1 and stuff?? | ||
| Thomas_lindemann |
dont mind at all tlindys@aol.com | ||

Speaking of GSXR vs Buell XB.... I went from a Busa to a Firebolt XB12R. Honestly, I don't miss the power. Sure. It's nice to open up the Busa and just have your ass get planted on that seat hump and your arms stretched! But after that, I'd take the XB any day. Believe me, even though I have a constant need for speed, I rarely ever took my Busa beyond 8k RPM--it was so freakin' fast. Anything above that range and I needed to be in the wide open desert. So if I was to be honest with my wants and needs, 100 rwhp is plenty good for me. Anything more and it is wasted 90% of the time. The XB's torque, lightweight, and meanuverability keep me very, very happy. | ||

It never ceases to amaze me how obsessed bikers are with spending money on expensive tuning modes to gain that extra couple of BHP above 6000rpm. Unless you are a seriously good rider and are riding the bike at it's limits (usually on the track) these tuning mods are of the Bling variety. IMHO the best thing you can do with your XB is set the dynamic and static sag to suit you and your use (track or road) and then fine tune the suspension to make sure this excellent chassis is work to its best ability. I am an 'elderly' rider of modest ability and other than a race pipe and XB12 airbox my bike is untuned. However the chassis is carefully set up for the track and as a result the bike can be ridden around or under EVERYTHING (including Ducatis) else on the track. OK it's a little frustrating to have R1s and GSXRs blast past you on the straight, but you eventually get far enough ahead on the corners so they don't all catch you again on the straights.....and I know it frustrates the hell out of the other guys to have "and old guy on a Harley" ride round them on the corners. Put your emphasis on the chassis not the engine... Just my thoughts for what they are worth. | ||

What the "old guy" said, I concur,sir!  | ||
| Tigerbythetail |
hi...........I generally agree with the "old guy". A lot of talking is done regarding how to gain more BHP (and so little is really done about it).....I personally have invested a lot of money in reducing the rotating masses and how the power is delivered (lighter primary components with 35/56)........I also have introduced CNC maschined yokes and different bearings for the steering to make the front stiffer....including a custom solution with a Matris M3 steering damper......I ride a lot of twisty country lanes and here it is useful to have the support of the steering damper to reduce the effects of bumps........the suspension is still an area where I will need to invest...the 2005 fork is OK for me (70 kg).........but I do have problems with rear end in particular in down hill section where the rear end becomes very nervoes. The first investment from my point of view and by far the most rewarding to increase the performance of an XB is the change to the Michelin Pilot Power.......this really transforms the handling and is actually cheap.........my main focus is handling and here the concept of the reduction of rotating masses makes a real difference. tiger | ||

Tiger, I completely forgot the tyres - probably the single best tuning modification you can make to the XB in my experience especially if you got one with the old 207s.. Great website BTW though my German was stretched beyond it's limits - this site is worth a look everyone. | ||
| Tigerbythetail |
hi.........Surveyor. Thx for the kind words. I am just in the process of translating the essence of the site into English. I gather in about two weeks time I will be able to upload a completely revamped version including the english contents........I follow a number of threads in the BWF and I particularly like the stuff Steve Slaughter has written. | ||
| Dstrat1 |
Old guy, you are so right , i see liter bikes all over town with inches of unused rubber on the edge of their tires, went to the track the other day and watched a good friend with 30 thousand dollars of ducati 996 with every last mod you could possibly buy get completely whipped by a young kid on an aprilia 125. I have done a little racing myself and it is embarrassing to find that too often it is us that is slow, not the bike | ||
| Garrett2 |
i agree with some of what is being said here, but some of it is just ignorance. not everything is about the twisties and track time, some of us do like to feel a big kick when we crack that throttle. some of you are rediculous. |
