Mennis -- that boot between the carb and the manifold is the third cheesiest part on the bike (first, kickstand switch, second, manifold to head gaskets) . .. . . replace it, it's cheap if your carb has the cables attached to the forward side of the bike, stock cables should be fine . . .. . . .do like Henrik sez, adjust em both alternately, and I think you'll get it nailed | ||

Mennis, Don't push the carb in dry, use a bit of grease. This prevents distorting the boot during assembly. | ||

Like a virgin. What Bluzm2 said. | ||

Will drilling holes in a XB12 air box lid impair any properties designed into the air box? For example, designed airflow. | ||

Hey everyone- I have a California bike and installed a Hypercharger. I put the breathers back into the carb via the "T" , no problems there, but now I have left over the line running from the carb to the Charcoal can, and the hose coming from the can to the old air box- can I take off the charcoal can now and just plug the line from the carb? Or what do I do with it? Thanks! | ||
| Sandblast |
Nevermind- figured it out- thanks Ferris. BUT- Now my hypercharger is rattling really bad- it is not constant but sometimes under acceleration or deceleration it will rattle really loud and its driving me crazy- if I put finger pressure on the butterfly it goes away. The middle screw on the back of the vacuum motor is backed out quite a bit I noticed, I dont remember if this is an adjustment thing and was always like this or what? Anyone have similar problems? | ||

Alright my speedometer and tail light are working now but now my bike isn't running correctly. Its been what i thought to a little spit back at about 60 70 mph or at constant speed and sometimes under heavt acceleration. Its almost like it skip a beat and start back up. When it happens it makes a sound similar to backfiring, well tonight i went out to eat and at an intersection it died, i started it and went on when i got to the resturant(sp) and came back out it was having trouble starting, it started once and black/dark grey smoke came out of the right side i'm assuming out of the carb. well to keep her running had to be constantly revving it and giving throttle when i got home i started it and theres a sound arounf the carb like an air leak, the boot might be loose but i couldn't check with hot motor. I hope you all have a sollution because if i can't fix it and someone here doesn't figure out what it is then everyone will have a chance to buy a 2000 Buell Blast with V&H and many small accessories. I love my buell but snce day one (not always the bikes fault) i've had to say "well as soon as i get this done it will be ok" its been constantly one thing after the other | ||

I'm still runnin' the stock airbox and filter. Just had it off and cleaned all the oil mess out of it and took a second look at how the filter fits into the inner housing. Check out the pic. At BEST, they are only using about 40% of the filter surface area, since the housing fits so tight. Does anybody know what they were thinking when Buell designed this?????  | ||
| Ara |
Yup, you're right. I long ago replaced the "filter housing" with a flat plate of alloy shaped like the cross-section of the filter but with two "ears" with holes for the bolts. It's simple and it serves to open up the surface area of the filter. The snorkel is a casualty of this change. If you like "intake honk" I recommend it. | ||

Bobpaul, the stock setup is meant to reduce intake noise at the specific rpm the EPA does the test. ( pull the helmholtz tube & you WILL hear intake sounds, including valve tick ) If you remove the snorkle ( helmholtz tube ) and use the venturi ring listed in the knowledge vault Carburetion, Fuel Injection section ( Venturi P/N 29179-88 Venturi Ring ) use stock bolt ( locktite blue ) and alloy strip as shown above (ends are cut to shape of & will fit inside of stock filter box w/holes aligned ). This is one of the 3 best setups for airflow & knee clearance. Force intake or clone is very good, but $$ and may damage carb, intake if bike is crashed on right side. Stock box, snorkle with holes filled (milk bottle tops ) and K&N filter as on forcewinder is highly thought of too. ( details in here somewhere ) Other setups may flow better?, these 3 have best knee relief. IMHO YMMV ( run a catch can! never have to clean airbox of spooge again! ( have to clean catch can instead )) | ||

The gutted airbox and venturi ring certainly look intriguing, but has anyone proved that it actually improves breathing and performance? | ||
| Bobpaul |
Aesquire, Thanks for posting the pic and the info. Looks really easy... no problems with the screws vibing loose? I got the venturi ring.... was only 95 cents! agreed on the legroom, as I have 34" inseam. that's the reason I've stayed with the stock airbox. Djkaplan brings up a good point... I wonder if removing it really does improve breathing. Helmholtz resonators do strange things with speakers (experience from a distant past life), the main reason they used it was to dampen out certain frequencies (as you have pointed out) but I always thought there was some kind of performance tuning advantage. Don't the engine designers call that "secondary" tuning? ...when they tune the intake runner or snorkel for ram effect. It's hard to imagine that Buell got much gain oweing to the restricted air cleaner, as shown in my pic. The advertisements from '99 claimed that the airbox inlet is in a high pressure area where the air is slightly compressed at the front of the bike, but they didn't explain the theory on how the airbox worked. Always curious on that one! In any case I think my next project will be making a bracket and removing the helmholtz tube. If nothing else it'll satisfy my urge to tinker! | ||

Greetings,wanting to remove plastic ducting from around tank on my 99 x1 lightning can anyone tell me whats involved once removed? | ||
| Reepicheep |
What does the snorkel in the XB actually accomplish? Is it simply noise reduction? Does it help protect against heavy rain? Is it a tuned length to address particular holes at particular RPMS? | ||

Tat developed a taller velocity stack years ago, its a good part that I've had on both my S1W and S3 with the Buell race oval. I haven't personally dyno'ed it, but I saw his plots years ago and it seems a worthy addition. It looks like this (shown next to a stock HD venturi ring).  It's a useful item if you have a gutted hemholtz box, or a race oval or Westtek. Won't work with the stock S2 filter height, would pinch off flow. He ordered a bunch of them at the time, minimum molding fees being what they are, and we have a bunch here still. They were $34.95, I think we can do much better, they're now $12.95. Part number is 5637, if you want one, order here or just give us a call. Al | ||
| Al_lighton |
A clarification, due to the number of questions I've received. That tall velocity stack is only useful on the tube frame bikes, NOT the XB series bikes. Thanks, Al | ||

I want opinions on the advantages/disadvantages of the Forcewinder compared to the Buell carbon fiber race filter. I'm running the Forcewinder now but may have a line on the CF Buell set-up. I like the way the Force looks, but it sticks out far enough to cause damage to the carb in the event of a laydown. Does the CF offer any performance gains over a Force? What is the hot set-up for racing Buells? Does the CF filter interfer with knee clearance? Will I have to get banjo fittings for the breather tubes to clear the backing plate on the CF filter? What do you guys run on your tube-framers? | ||

I have an '02 X1 with a Forcewinder. I ran the breather lines over the engine into a American Sport Bike catch can with a hose from there down to near the exhaust outlet. I like it, works/looks good, don't know about HP gains, don't worry about its effect on bike in wrecks. Frank   | ||
| Oldog |
Ftd Looks Sweet! here are some numbers http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=47623&post=388610#POS T388610 old school xr2 thread How do you like the cleaned up under tray  | ||
| Reepicheep |
I saw an S1 highside with a forcewinder. The filter was shredded, the intake scooped a mouthfull of asphalt, but the carb did not appear damaged. The forcewinder even appeared serviceable, though it needed a new filter. | ||
| Cowtown |
You may like this,   I made a venturi ring ¾” thick, 3 ½” OD, mounted a K&N RC-1790, 5” diameter x 3” wide. I’m 6’ with a 36” inseam, during aggressive riding my knee will rest against the filter. As you can see I used banjo bolts. | ||
| Buelliedan |
If you do destroy a Forcewinder filter they are dirt cheap to replace on e-bay now. | ||
| Ftd |
Olddog, I like the CF undertray and tank inserts. All came from American Sport Bike and fit/look great. Frank  | ||
| Devdawg |
Al, I'm running the tall velocity stack and Westtek intake...both from American Sport Bike. Seat of the pants dyno says it was a very good addition. I would recommend it to anyone considering the tall stack. | ||
| Gundog |
Cowtown, How much was the filter, and where did you get it? Thanks | ||

DJ I'm running the CF on my M2. I think the Forcewinder *looks* a little better, but I believe there is a slight performance edge in airflow when running the Buell race kit (which I am) and long duration cams (which I am)and high flow carb;i.e HSR42 (which I am). I have a 34" inseam and my knee rides up against it which irritates the he!! out of me but I'm getting used to it. If stylin' is your game, go with the Force. If all-out performance is your bag, well, you choose. I did have to cut down one of my breather fittings to clear the frame, as it threads in further to clear the back plate of the CF filter but didn't need the added expense of banjo bolts.  | ||

Frank, The X1 looks really great. I'm a sucker for Black and Nuke blue lightnings. IF X1's had looked like that on the showroom floor, I bet I would've bought one of those in '99 instead of my S3. Gorgeous. However, your breather routing is perhaps suboptimal. Conventional wisdom says that once the breather lines leave the head fittings, the tube should only run downhill. Otherwise, a trap is formed in the line, causing blockage, then burping. You'e got a catch can, so if it isn't needing to be drained too often, and you're not blowing seals, well, maybe it isn't worth worrying about. That's just one of the reasons why I really like the XB rocker box conversion. The lines start high on the top of the engine, which allows the breather lines to be run to virtually any place on the bike. Well, that and the fact that much less oil gets breathed out to begin with, since gravity pulls oil AWAY from the breathers rather than dumping it in. Al | ||

Gundog, I ordered it from 4filters.com, cost 35.55, and I don't think they charged taxes or shipping. Here's a front view so you can compare how far it sticks out to other systems.  | ||
| Gundog |
Thanks for the photo. I think I'll give it a try. I've been switching back and forth between a de-snorkled stock airbox and the race kit CF on my M2. With that little K&N, those big jugs are on display for all to see. |
