http://www.roadracingworld.com/news/article/?article=27280 "Section 5-44-1 (add) Quick-shifters (devices that cut ignition to smooth shifting) are permitted. The use of pneumatics to aid shifting is not permitted." I was on DynoJet's website, and went to the Power Commander page. The Power Commander is no longer available for the Buells, and that is needed to use their quick shifter. Is there another quick shifter available? | ||

Dale Walker's Power Shifter just may work. The description says it'll work with most every motorcycle. I used to deal with Dale back when I had the Bandit. A great guy to work with, and do business with, he has the same attitude as a lot our sponsors have. http://www.holeshot.com/ In 1991 Dale developed the Electric Powershifter 2. After a year of testing, he came up with the most user friendly unit yet. It's a snap to install, works on just about any motorcycle, and is easy to dial in with the external kill time adjustment. It can be used for dragracing, roadracing, superbike or GP, Harleys, quads/ATV, and shifter race karts. It's awesome! | ||

Mike Ciccotto is riding a BMW for the "8 hours at Daytona". http://www.moto-st.com/Events/2006_Daytona.asp#EntryList Only 2 Buell teams listed. Neither are listed as riding XBRR's in the SuperSport Twins class. I believe that the entry list is closed, so no XBRR's at Daytona. (Message edited by JScott on October 10, 2006) | ||

This caused quite a stir. http://www.roadracingworld.com/news/article/?article=27308 | ||

Like a lot of people, these issues are always iffy and I'd always ASK before putting a lot of effort into something that MIGHT NOT BE ALLOWED. ANYTHING that looks like quick change can be iffy. I have asked about my bikes being 1169cc XB9 bikes - the XB9 is listed for Grand Sport Twins - but the HP of my bikes puts them in the Super Sport Twins class. You can bet I'm asking for an answer before I finish building the second bike! Ditto for quick change hardware. The stock swingarm may actually be better for quick changes than a swingarm with the adjustable sliders. I'm reading the rules there as well but will NOT go and put time/money into fabricating something without asking first. I'm always amazed when people do custom stuff for racing and then bitch when they get busted. | ||

Eboos, Did you find anything out about a quick-shifter for a Buell? Regarding the quick-shifter? Do you really think the Buell trans is smooth enough to quick-shift? It is not near as slick as a Japanese tranny. I have never been able get a good upshift without using the clutch. Am I doing something wrong? Clutchless upshifts like a GSXR would be sweet. | ||
| Eboos |
I haven't much looked into it. To be honest, I never tried a clutchless shift on my bike. For poops and giggles, I'll give it a wack. | ||

A quick shifter can be done. If it couldn't I wouldn't be able to ride mine!  (my left leg is paralyzed for those that don't know) | ||

I shift my 12R up and down without the clutch. That said... I don't shift down w/o the clutch very much at all (maybe 5 times in 30K miles), but in JUST the right conditions it's nice and smooth. Shifting up without the clutch is easy... just roll off the throttle a little and give it a yank (or a shove, depending on your configuration), then whack the throttle back open. | ||

I had to race one month when I had surgery on my left hand (skin graft and a fingernail pulled out - long story) so I could just barely use the clutch on the start because I used a latex glove to keep the stitches from catching inside the race glove and baby powdered it so I could get the leather glove slid on over the latex. I tried downshifting without it and scared myself s**tless. I couldn't use my hand to squeeze the clutch more than twice a lap but went 3 races without using the clutch for upshifting. Like has been said, roll off, bang it up. Nowhere near as nice as the ignition interrupt on the true quick shifters but really does work OK as long as you unload the transmission. The sweet thing about the real quick shifters is you don't have to get off the throttle at all. I've tried it and it is amazing... though for the $$$ - I'm going to spend it on more seat time. Saving 0.05 seconds every shift isn't worth the money right now. (Message edited by slaughter on October 11, 2006) | ||

Downshifting is just the opposite up up w/o the clutch ... I've never done it at any great pace (well, once on accident ) but as you're coasting just blip the throttle and shift down. Immediately let go of the throttle. I don't think I'd want to do it in the low gears, but it seems to work alright down to third and below 5K RPM. Again though... I don't recommend it... I mostly just practiced it a few times just to know what to expect should I ever need to do it due to a broken cable or something. | ||

The reason I knew about Dale's shifter was I had one on my Bandit. Steve, I believe you'd save more than just .05 secs per shift. If I can find my old time slips from drag racing I can show you I cut my time a whole second in the 1/4 mile. Amazing is right! There's nothing like full on up shifts! | ||

It's something I'd love to have but if I put together a second bike for a MotoST team, I'm really pinching pennies now. gotta get the Traxxion AK-20 cartridges for both bikes, upgrade the old bike to the 43mm forks, another Penske and then bring the second motor up to the first motor as soon as I get official ruling on what class the bike is legal to run in (XB9 with overbore) - and all the other spares... sheesh. I'd love to have an interruptor type shifter but that's almost one race's worth of rubber for an 8-hour race. | ||

Steve, If you abide by the HP limit I bet they won't care which class you run in. Restrictor plate? | ||

These are supposed to be extremely good quickshifters and are pretty good on price too. I was thinking of these for our own bike. http://www.moto46.co.uk/Page_3x.html If you don't want to go the whole hog, they also do a Supersport legal ignition interupt switch that works on the horn button. Just hit the switch when you change up for smooth clutchless changes | ||

Blake, We'd rather run the SST class - I'm waiting to read what they say on the MotoST discussion board. The weird thing is that unlike FUSA, the classes are limited to specific named bikes AND HP. My bike STARTED as an XB9 - putting it in the GST class - but its HP puts it in the SST class. Gotta get it figured out before putting the second bike together... Dang but the race in March is much closer than it appears. I'll PM you with the "HYPER-MONDO-ULTRA Secret" rider list for Lavin-Yurassov Racing. It looks really interesting. | ||

Best of luck Steve! Hope it gets cleared up real soon. Nothing like waiting when you have a deadline, and the one you're waiting on doesn't. | ||

There is a quickshifter available for a Buell. Several teams are using them. Hal's sells one. It's basically a Techtronics box with a Dynojet switch. It works great; wide open clutchless upshifts. As far as downshifting, I haven't used a clutch for anything more than stopping and starting for several years. Just blip the throttle and it goes right in. Of course now with the slipper I should use it and get my money's worth! | ||

My translogic shifter works on the same principal. It has an ignition interrupt and a high speed linear actuator that pulls the lever. It's the triptronic system you hear so much about in ferraris etc. There is absolutely no problem with using a quick shifter on a Buell. Even with my 03 transmission  The only issues I've had with it in the past year or so have been purely operator error. Getting a slipper clutch dialed in seems to me like the thing these teams will be sweating. To get them (For a racing slipper clutch)right is more involved than just plug and play. | ||
| Glitch |
It has an ignition interrupt and a high speed linear actuator that pulls the lever. So, the upshift is handled with the interrupt, and the down shift with the actuator? Is that correct? With mine, you still had to down shift the "old fashioned" way, with the clutch. | ||

The XB9 is listed as an eligible bike in both GST and ST, making it the only bike listed in two separate classes in the Moto ST rules. The XB12 is listed only in GST. | ||
| Eboos |
Instead of listing specific models, if a bike will meet the equipment, power and weight requirements, it should be allowed in any of the classes. If they are going to list specific models for certain classes, then those should just be the minimum class allowed for that model. | ||

Yabbut I've got the XB9 with HP that bumps it into SST (about 107HP) and that's the class we want to race. I'd have to de-tune it to drop into GST. I've never run it on 98oct fuel either so don't know if the Sunoco spec fuel would add a teensy more HP. Gotta get that figured out before I build the second bike. | ||
| Diablobrian |
nope, the actuator works both ways (otherwise I'd always be stuck in 5th gear  ) The ignition interupt does not work as well on the way down. On the way up I just keep the throttle pinned. On the way down I still blip the throttle or tap the clutch lever to make it smoother, or it sometimes does not complete the downshift. It's not cheap, but translogic makes quality components. the actuator is far more positive shifting than the electric solenoid shifters that are on the market. I researched this a lot before buying the system I did. Since they aren't allowing compressed gas shifters I would recommend the actuator. It would suck to hit a false neutral in a race. The translogic also goes up and down unlike a lot of the solenoid shifters. | ||

Gottcha. Thanks. |
