Don't know a thing about Nology Wires except that if you want a good price on them, check out the JC Whitney Catalog. They are in there.

After listening to Erik Buell talk in depth about the history and design of the XB12's velocity stack at the Buell 20th Banquet, I wouldn't think of messing with it.
There are so many other avenues to take to add to the performance of an XB12 that this would be my last resort. |

Nevco:
Good point...you may recall my comment when folks discovered that a REALLY well thought out design for the stack yielded no marginal improvement over stock.
It was something to the effect that some really good engineers, being paid, had worked really hard on it for a long time. My bet, knowing a good many of them, is that they covered most the possible iterations.
By the way, remind me sometime, to tell you some of the performance things that Buell has wondered on to COMPLETELY by accident.
Smart is nice....smart and lucky is divine.

Court...Agree totally.
The interesting thing about the velocity stack and the cone combo it is that Erik figured that one out back in his racing days and shared the information with his R&D department while they were working on some intake air flow issues with the XB12.
If I remember correctly, Erik's experience with the cone/stack combo preceded his original Buell motorcycle manufacturing company. Well, at least it sounded that way and I would hate to misquote Erik. Can anyone confirm this? |

Bill, thats the way I understood it as well.
Anothering interesting thing about the cone & stack deal, has anyone looked inside of a hypercharger aircleaner? If you get past the gimmicky butterflys, you would notice there is a similar setup going on inside that unit. So it would appear as if they actually did do some actual work to make it flow correctly. |

You guys make it sound like Erik Buell invented the velocity stack.
I was running velocity stacks on my Triumph in 1978 and I can assure you they've been around decades even then.

Rocket, its not the stack but rather the little inverted cone deal that fits over the top of the stack. The XB9 doesnt have it, but the 12 does. |

Like BASF, Erik Buell didn't invent alot of things.....he just made them work better.
Look around for something as slippery as an RR-1000. Don't even think about a Hayabusa, you're gonna have to do lots better than that...and the 'Busa is a darn slippery bike.
Sometime ask me where Erik Buell tested the early designs. I can tell you....but...well, you know the rest.

Court;
Ya gotta quit teasing us with this "..remind me to tell you sometime..." crap. TELL US!!!! That's what we come here for each night...Buell Mecca. C'mon, spit it out! |

Youo're just going to have to corner him at a Buell event and force-feed him beer till he starts hemorrhaging information.
Man, does that word look wrong. |

Rocket...Thanks for pointing that out.
Didn't mean to make it sound like Erik invented the velocity stack. Was implying that he employed the stack'n'cone concept to rectify an air flow problem he had way back when. Then conveyed the concept to his R&D staff to help solve some air box issues with the XB12's.
Don't know if you ever met Erik, but if you did, you would have a clear mental pic of the posts about him, especially Court's. One would naturally expect Court to always take the Pro-Erik/Buell position. However, after meeting both, I can assure you that Court's posts about Erik are a true insight into the man and Court is most certainly not playing Corporate Cheerleader.
Erik is a typical Type "A" personality on a mission. A real hands on type that would love to sit and tinker with you and enjoys the challenge of going against the flow to create a better bike. Erik is a naturally enthusiastic and exciting individual, not a corporate stereotype. When he talks, it is from the heart not the wallet.
I can only imagine that not being in a position to manufacture the different format bikes we ask for is a frustration for him. However, in the sport bike and streetfighter class, he has done quite well given the limitations BMC faces in order to survive and grow.
Am still looking for some input from a higher authority concerning when Erik first employed the stack'n'cone concept in relation to beginning his MC manufacturing days. Not that it is important, I just like timelines. As Dyna is the only one that responded and we heard the same presentation, we could be either right or wrong. |

A good story told to me by JB2 (who tells it better than I can );
But - at one of the early Brag events, everyone was lined up to go on a group ride. Except that Erik's bike, parked at the front of the line was missing it's rider.
Everyone was waiting - people scurried around looking for him - until someone noticed a bike at the back of the pack being revved repeatedly. And there was Erik, on the ground with a screw driver adjusting air/fuel/idle to dial out a "just-on-the-throttle" cough on a customer's bike.
How about that for hands-on from the head of the company.

I have had the pleasure of having talked to Erik several times in the past 4 1/2 years that we have been a Buell dealer and I,became a Buell junkie!
I always come away from those talks, mostly informal talks, very impressed by him. Not the corporate type for sure! Very refreshing.
Ride to the edge!

Henrik...even with my limited exposure to Erik, I would assume that is typical behavior for him.
Of interest, at no point during the 20th did I feel like he was meeting with customers. It felt more like he was simply interacting with friends.
I also appreciate Court's portrayal of Erik as a family man. Have seen way to many family failures among corporate exec's due to their career involvement.
Heck, I even failed at two marriages for that very reason. Thought I was doing the best for my family and learned the hard way that money can't buy happiness, but it can support your ex-wives quite well. LOL |

Damn, I wish I heard Eric's talk at the 20th about stack design! Here I am trying to "reinvent the wheel" on my own, with nothing to go on but 30 years of machine design. I must admit I'm having some fun with the solid models during the months when riding is impractical here in Jersey. I've had some good suggestions from some knowledgeable folks but I'd really like to talk to an expert before I cut metal on the next one.

Erik's use of the cones with velocity stacks initiated on the RW-750 protoype in 1981. Being a rotary valve motor, it had it's carburetors aimed sideways right at the inside of the fairing. When a more aerodynamic fairing was fitted, the engine started running wierdly. Looking for ways to improve the flow without building big bulges in the fairing over the carb mouths led to making a matched set of big radius velocity stacks with cones attached to the inside of the fairing. It cured the problem. |

I bought my 26 tooth sprocket from DFK and they were great! Not only did I get my part right away, they sent some stickers and some company notepads. They were easy to talk to on the phone and quick to get things out!!! |

Erik's use of the cones with velocity stacks...
Kinda makes ya wonder why he left 'em off the XB9.
Not complaining just wondering, I got the 12 box top from Buckin as soon as I heard this was the way to go. |
