I know that Baker makes a 6-speed conversion for XB's up to 2005....anyone know of any for the 2006 and up??? just looking for a lower cruising RPM..... | ||
| Alex |
Can You give me a part number for a Baker 6 speed tranny for XBs up to 2005? The last time I asked at Baker they said "No, nothing like a 6 speed for XBs. Only Sportster/tube frame Buells." Regards Alex | ||

Check the Drag Specialties or Custom Chrome catalogs. They list a Baker 6-speed for Sportys that says will also fit the XB's. It's the same gearbox between the two bikes. As long as it fits the Sporty of your year, you're good. | ||

IIRC You cant put in a Baker XL6 without a trap door. XB = no trap door. What about this? will it work with my 03 NineR? Steel Long Life Pulley Stock Sportster/Buell transmission pulleys are made of cast iron in 27 and 29 tooth configurations. Replace your stock 27 tooth pulley with our 26 for an instant 4% increase in torque to the rear wheel. In addition to 4% more torque to the rear wheel, our pulleys are lighter and stronger than stock. Less weight translates to reduced ‘flywheel effect’ and quicker revs. weight comparison: Install one of these pulleys with our XL6 to significantly increase the performance of your Sportster/Buell and reduce the cruising rpm. * Stock 27 tooth cast iron pulley 2.875 lbs * Long life pulley, 26 tooth 2.375 lbs | ||

So no chance of a 6-speed on the XB????  That is my biggest complaint about my XB9S! I want that extra gear!!!!!!!  | ||
| Wcbrracing |
I was wrong about the years, thanks guys.... I checked bakers website again, 1991-2003 years only.....damn, I want that extra gear!!!! | ||

What about changing out your drive sprocket and belt pulley ? There is a part that is the Canadian inventory (dont ask me why it isnt domestic) but it lowers your final drive ratio, that should help lower your Rpms. Guy at Back to Track 2 swore by it for his XB9R | ||

i've been real happy putting 29 tooth front pulleys on my tubers. not sure if the belt on xb's has enough slack to do that or not. gives a lower rpm for highway and a higher top end if the motor will pull it. tim | ||

"So no chance of a 6-speed on the XB????That is my biggest complaint about my XB9S!" Hold on, there is another way to get overdrive on your 9S. You can make all of you gears taller. Install an XB12 Primary drive. XB12 riders put the XB9 Primary on 12's to lower the gearing. Put a 12 on ur 9 and you lift your gearing. + It cost alot less than a baker trans. | ||

Here are a few #s Disregard "current"  Stock XB9  An XB9 with a XB12 Primary drive  | ||

Baker claims a drop over 500rpms less in top gear (overdrive 6th). This system drops RPM 500 RPM @ 87mph (overdrive 5th) What is is ur normal highway cruz speed in 5th? Here is an example. If your cruz speed is 70mph in 5th you can use 402 less RPM, a drop of 11.7% In general terms the new 4th gear will be like you old 5th.  (Message edited by barker on January 24, 2008) | ||

Has anyone here on Badweb done this? I commute on my XB and not race it. I dont think I would miss a little low end for my purposes. (Message edited by roadkingtrax on January 25, 2008) | ||

Roadkingtrax, I can run some numbers for ya.  Buell Nerd Alert!  I can tell ya how much your RPM's will change with a 29 front sprocket. xb12 or 9? What is your normal high cruz speed? (Message edited by barker on January 25, 2008) | ||

I'm used to having a 6 speed (I've a CBR most of my street motorcycle years), but remember, when you have a powerband like a Buell, it diminishes the need for more gears. If you want lower cruising rpm, I'd just gear the bike taller, like suggested above. I guess I just appreciate the simple design solution of Buells. | ||
| Roadkingtrax |
Well here in Arizona...speed limits are purely a suggestion. I cruise about 75-80 and that puts me close to the 4k ballpark. I am wondering what I could do to drop it down some. Of course,...I could just drive slower...what fun is that...Nerd Away XB12r BTW Tim (Message edited by roadkingtrax on January 25, 2008) | ||

While I tend to agree ,and it's what I did on my Harley, I'd personally rather have an overdrive 6th on the Buell. | ||
| Djkaplan |
...but remember, when you have a powerband like a Buell, it diminishes the need for more gears. You would think that, but XL based engines don't really have much of an rpm spread to work with in each gear. I think on most of the twisty roads I ride on, the Japanese bikes are actually shifting less than I am. | ||
| Barker |
My calculations -6.9% change from a stock 27 tooth @ 75mph in 5th with a 29 tooth front pulley: You drop 254 RPM. @ 80mph you drop 270 rpm. Theoretical top speed goes from 143mph to 154mph. IMHO Not that big of a change. | ||
| Thespive |
How much is a 12 primary setup, I would love to lower my revs at speed, the bike is plenty fast as it is. Also, wouldn't that throw off the speedo? And DJ, I disagree. I ride The Pace in 3rd gear and hardly ever shift on twisty mountain roads. The 600s I follow are always shifting. This could be as much the rider as the machine though, but that is my experience. I would guess the liter bike have enough torque to avoid that much shifting. --Sean | ||
| Roadkingtrax |
You are correct there Barker...not much of a change. Although it was meant to be a joke, I could gain that amount of RPM decrease and a little fuel mileage by managing my throttle hand a little better. It almost like they dont want us to speed...j/k Tim | ||
| Rah7777777 |
One of my problems is i'm used to a 6 speed. so everytime i hit the highway i'm looking for that 6th gear (still have not found it!!!) plus I like the powerband just as is, and don't want to screw it up with gearing. So just someone, please build a good 6 speed for an affordable price :-) | ||
| Knotrider |
Have you thought about a final drive chain conversion ? You can do whatever you like with the gearing with a chain and sprockets. Putting a taller rear tire on will help you a bit as well. | ||

I don't know if this is applicable to the other XBs or not, but let me tell you about some of my Uly experiences. First gear on the Uly is too tall. People who want to use the bike in the dirt frequently switch to an XB9 primary chain, which lowers the gearing by 11%. There was concern about the effect of this mod at highway speeds. The difference between 4th and 5th gear is about 11% so you can simulate the mod by riding in 4th instead of 5th. I did an experiment, riding the bike to a city 90 miles away in 5th, and returning in 4th. It was all interstate, and I ran about 75. Gas mileage is BETTER in 4th gear. The throttle response of the bike is better in 4th. Other people have tried my experiment and some get better mileage in 4th and some don't. Our current theory is it has to do with rider size and how much drag they produce. I hardly ever run in 5th gear any more. The fastest I've ever had the bike is 110, and even there I was in 4th. I tried 5th and it just didn't have the power to pull it at that speed. Pretty much ended my interest in a 6th gear. | ||

I guess the only downside would be accelerated engine wear from the extra revs. | ||
| Rah7777777 |
My opinion on my XB9S is just add a 6th gear, and leave the gearing on 1 through 5 exactly as it came from the factory. this, to me would be perfect. could even make 6th a pretty tall gear, as if any power is needed, you can just downshift. but maybe that is just me. | ||

Coming from imports to my 12R I do occasionally get annoyed with the lack of a 6th gear, and a bit defensive when a rice rider talks smack about my top-end (neighbor with a Hyabusa wants to race  )... ...but it only bothers me until I think about it. I don't really need to shift much on my R -- on a favorite S turn of mine I shift once coming out, my CBR would have needed 2 shifts or it would have started screaming. My buddies always ask me why I never shift on rides through the hills like they have to on their imports -- I just smile. Yeah my neighbor's 'busa will kick my tail in a straight line -- if we are on a airport runway. On the streets of my city or the turns in the area around here I flick in quicker, pop out faster, work less, shift less...etc., etc. I'm not bashing imports -- I am saying that the bottom line is if I had wanted a track bike I would have chosen a Triumph Daytona 675. If I wanted SR71 like supercruise I would have gotten a 'busa. A 6th gear is nice, but on the grand scale of things, I don't need it -- the same as my buddy's HEMI Ram Daytona, it does just fine with 5. I do kinda like the idea of a bit more play in 5th though -- I use 4th much of the time and 5th isn't gonna pull anyways. | ||

I'll try these ! http://www.americansportbike.com/shoponline/ccp0-p rodshow/A17151.html A17151 - XB9 11% Primary gearing increase Kit, 03-07 XB9 11% Primary gearing increase Kit. These are the OEM parts from the XB12, which has an 11% overall gearing increase. For those that just want to go fast, this is the easiest and best way to get there. However, don?t put this in if you haven?t pumped up the engine a little or dogged low end response will be yours. Easily installed, with the possible exception of the monster torque needed for the rotor nut (240 lb-ft). We highly recommend using the Service manual while installing this kit. Note: WILL NOT WORK on 08+ models, a different front sprocket and a retaining BOLT is used on 08_ models. We can get these parts, but we do not stock them. Price: $193.10 Buell original part nº and Price in www.lshd1.com Primary Chain - 40147-04 - US$ 50.40 Sprocket - 40290-04 - US$ 84.00 | ||

I've done the same thing with a custom primary for an XB12. It lowers the revs at 87 mph from 4230 to 3830 rpm. How do I know that? I've just had my licence suspended for doing 3830 rpm in a 2700 rpm zone  |
