If you didn't do any of the nats rounds so far then they probably didn't send anything. I wouldn't be too concerned.

A quick shifter is an ignition/fuel cut device. Basically it means when you change gears you can hold the throttle pinned (ie/ without backing off) and just hit the gear lever and it will change gears.
There a couple different types, the mechanically operated ones are usually found inline somewhere on the gear change linkage, when pressure is applied to the lever a signal is sent tot he ecu and fuel and ignition is cut for a predetermind time (like .2 of a second) this allows the gear to slide in easily without having to back off the throttle.
The other type is like i explained above, you manually push a button to cut the fuel/ignition.
As swerve said, they allow a slight advantage when going through the gears which over the course of the race adds up.

(built and raced drag bikes for years in uk so know their sound AND ADVANTAGES)

approx 1/10 of a second over 4 gear changes on a 1/4 mile.......... so work that out over 15 laps!!!!!!!!!!

Do the culprits really need them to win

There is two bikes that standout from down south in my mind. Straight away you can tell the shifts sound way different to other bikes. But what would be the fun in saying who? When ya listen to quickshifters on every bike in the US for 3 years it an't hard to tell.

Quite funny how a HORN button can be used for a quick shifter tool on some bikes if you know how and where to wire in the correct diode

You must have heard the bikes I heard as well then

is it better to not name the two or make everyone look as if they the ones who are not complying with the rules........
Dom, maybe get a group of dads together (maybe just two )who's boys dont ride in that class and get a technical inspection done ..........

Holy shit,You mean actually put your money where your mouth is and make an official protest instead of whinging and bleating to anyone that will listen.Read your rulebook first though,Wouldnt want too see you make a fool of yourself,7-4-1 too be precise

yeah i think i counted 3 bikes all the same make, if something is mentioned as briefing that they are not to be used in any way shape or form you shouldnt need to protest. Not my class though and even if it was i wouldnt bother...

Did the brand start with an "S"?

**FROSTY:Me** · 9th February 2009, 17:16

A thought here.why not pull the top 3 bikes in each race in each of the two classes for inspection.

possibly the bikes might have to be actually ridden...modern KIT RACE ECU's have quickshifter functions built into them...ECU's know what gear they are in...

So nothin noticable externally.

**Sketchy_Racer** · 9th February 2009, 20:30

Check bikes with Horn buttons and passing flash light buttons.

**CHOPPA** · 9th February 2009, 21:38

Yeah i think the problem was with bikes with manually operated systems by switch, they were on some yamahas cause the yec or whatever it is has it built in to be able to be used. I asked sam smith about it cause his was not one of the bikes and he said having to flick the switch seems just as hard as changing gears well so he couldnt see an advantage anyway.

They did sound cool though! Sorta just makes a bit of a pop through the gear changes

btw this is only my fairly uneducated points of veiw

Still need a seperate switch of some sort though. Most ECU's or add ons have the capability to run a quick shifter - easy to check either way.
I did notice in Timaru that one young fella was clutching full throttle gear changes motorcross style, and another changing on the limiter, both could sound like a shifter because of the limiter.
Gareth Jones' R6 "cracks" slightly when shutting of the throttle - I can assure you this bike has no quick shifter.
His and Sams bikes are tuned properly and with a kit ECU the extra rpm make the bike sound totally different, not because of a quickshifter.
