Oh yeah. Forgot the accidental wheelie. Couple of years ago some kids about eight years old were hounding me at a traffic light to do a burn-out. I shook my head "no" a few times then one of 'em said,"You won't 'cause you can't!"
BINGO! That's the button!
The old Dunlops would light up pretty easy. The brand new Metzler hooked up instantly! A hair's breadth from looping it and a hard landing from the sudden chop. Scared the wits out of me. Must have impressed the heck out of the kids, though. |

Eric! Where ya been hiding man!? Glad to see you back on BadWeB. Got any new tales? 
Bomber,
I thought almost all Japanese bikes had cush drive hubs. Every one I've ever seen apart does. Haven't seen one apart newer than a 1997 model though. Still, I'm pretty sure they all still use a cush drive rear wheel hub. |

Thanks for the welcome, Blake. Been keeping a low profile over at Sportster.org but they got a thread going about "colours" (club patches) being banned at the Laughlin River Run because of a shootout in a hotel lobby last year between rival biker gangs. Anyway, a lot of chit chat about freedom and making us all look bad and so on. None of it really my cup of tea.
Then someone posted about hearing about "coloureds" (Afro-Americans) being banned from Nevada for the weekend and "My daddy was in marches in the sixties..."I thought it was bait, quickly swallowed, but I now think it was maybe real. In either case, I felt a need for more intellectual company, so here I am again.
No new tales. Never finished "Dances with Storms." Looking forward immensely to Supersplash. There'll be one for that!! You should come up!
I'm really finding this thread to be gripping. My riding bud, with an S1 and a ZRX says that the Kawi dealership says says, "No need for a clutch when up shifting."
A Volvo I had a few years back (Yeah,car) had a manual that said depress clutch pedal fully to the floor.
I'd love to speed-shift through the day! My clutch arm gets dog-tired after 6 or 7 hundred miles of twisties. (You've gotta see the Pacific Northwest!) Convince me that it isn't hideously expensive and I'm gonna thrash this puppy some more! (Previous tranny woes sorted by replacing the whole thing with a slightly used newer one,BTW.) |

I've not speed shifted (not used to how these shift yet) but, shift hard and fast, and going into 2nd & 3rd, the wheel comes up effortlessly. |

Eric,
I'm sure speed shifting is harder on the dogs and gears than nice easy clutch actuated shifting, but speed shifting seems to work smoothly under hard acceleration. It seems to be a bit herky jerky in more casual less aggressive scenarios. I mostly speed shift on the race track. It also helps to use a GP (reversed) shift pattern. |

Other than to revel in the feel of the tranny action when you do it (which may be its own reward), the purpose of speed shifting is?
To save clutch wear at the cost of tranny wear in a race situation where the clutch may not last the race?
To reduce the time in which you're not on WFO in order to save a thousandth of a second per shift?
To show off to yourself for your coordination? (No offense intended, its probably my prime motivator.)
In any case, if the cush drive on a race-rep cushions provides the same cushioning as the belt drive and primary chain slop on a Buell engine, then, all else being the same, and I think the Sportster tranny has a good reputation as being relatively bullet-proof, then if you can speed shift on a Kawi then you can on a Buell?
As with everything we do, we have to consider tranny parts to be "consumable items" and budget for occassional replacement as a cost of flogging the suckers. You can probably get 100k miles out of these machines and 30k miles out of a set of tires if you never rev over 4000 and never go over 55mph. But who'd want to. After that, you have to weigh the fun factor against the cost.
On a different note, an alternate definition of speed-shifting occurs to me: to keep the throttle WFO when shifting and just use a quick clutch to unload the tranny for the shift. This was a drag racing technique (amongst teenagers) in my youth. Not sure if it has any point but would use up a lot of clutch. The clutch would probably slip for quite a time. |

Seems to me the shift forks are the weakest link in our trannies. |

Eric,
On the track or hard after it accelerating on the road, a speed shift gets you where you want to go a little more quickly. It is the manually operated equivalent to the ignition cutout pneumatic shifters that the pros use.
I've always called the WOT fan the clutch shift a "power" shift. Not something I want to do when I'm leaned over exiting a turn.
Rick,
I think the forks mainly get abused when the shifter pawl gets out of adjustment/position. I've literally stomped on my shifter when upshifting. I can't imagine bending a fork unless something is preventing the dogs from engaging normally. |

I broke the belt on my race kitted 1999 S3 "speed shifting" from 1st to 2nd. It would pull the coolest speed wheelie while doing it. I stopped doing it after breaking the belt. at the time the bike had about 35,000 miles on it. |

A proper/smooth speed shift should not hurt a healthy belt. If it does, I'd hate to think of the stresses to which the transmission gears and bearings were subjected. I've never tried speed shifting from 1st to 2nd, that definitely would be a difficult speed shift to execute well; the engine speed climbing so terribly fast would require very precise timing. |

Hey Glitch,
You said your 9s will lift the front end "effortlessly" in second AND third? Is this before or after you put the race kit on. I'm starting to wonder what the deal is. I'm not a big guy- 5'7" 165lbs and my 9s does not come up easily (except in first gear). Well when I romp on it and run through the gears it may come off the ground a few inches, but it doesn't loft the front end.
I have gotten the font up a little on a clutch wheelie in second, but only a small one. Not comfortable with the whole clutch wheelie yet. I'm to used to dirt bikes and being able to just open the throttle in about any gear and riding the rear forever.
I guess thats one of the reasons I started this thread. I've loved to ride wheelies ever since I was a kid, and now that I'm hearing about other guys doing it I'm feelin kind of cheated. Especially since I just chunked down 10 grand. |

"Is this before or after you put the race kit on."
It's always had the race kit, bought it that way.
And yeah, I've never had a street bike wheelie so easily. Just get in the power band and go. We're about the same size, I'm 6" and 160lbs. From what Scott Zampach said, the race kit really wakes the bike up. You really otta see this guy on an XB9R. He's got a Speed Triple that'll rip too. |
