Lights! Action!

[oneofsix]

The Boulevrd is fat enough to trip the lights.

Well it aint the rider unless you had too many fries with your latest tag

Lets start a, Stationary Lights Action Group!

Don't you go slagging off this thread

I think it's just the placebo effect put to good use.

Yeah. Like I have poor powers of observation. :-)

[Big Dave]

That will cause my engine to cutout

You just have to be smarter than the gearbox.

Yeah, neutral would work funny how I'd automatically do that when on the bike but focus on the cutout switch when behind the keyboard.

What about those early triumph stand switches back in the 90's. They would cut the bike out when it was going.

Ouch that sounds like great fun. Barrelling down the motorway at 90k and the bike cuts out

only 90k because we are talking 90s trump think I'll run and hide now.

Arrow -> Indian.



Highway wasn't so bad. Just pull the clutch in and brake.

Low speed cornering was an almost unavoidable drop.

[Orca]

Never had that problem on a K100. Could probably loan you 20Kg and still manage the lights.....

That advise for cyclists looka as if it might have been dreamed up by some blind ignorant twat who has never even sat on a bicycle. Fuck all works on a bicycle.
Not sure if aluminium will create the inductive field, but I'm guessing carbon fibre won't, and being that most bikes thess days that aren't made of aluminium are made of carbon fibre I don't imagine you'll see too many cyclists waiting for the lights to change.

Has always worked for my Alloy Bicycle. And for the GN as well.

Not 95%, definitely 100% of the time.

(I use a turn signal, with very little traffic, on a daily basis)

My MT is a large hunk of metal that activates road loops and is a chick magnet also. Only problem is they are mostly loopy also.

[sootie]

Dave and Sootie, just to clarify how they work, they sense the inductance of the loop, the vehicle acts as the inductor core. No vehicle, low inductance, big vehicle, large inductance. Magnetic vehicles are up to fuck all cos the fields don't affect each other. Voltage induced by speed will be very minimal due to the low magnetic field strength (which would induce the voltage in the vehicle anyway), and the sensor looks for a frequency change due to the inductance change. Maybe riding fast into a loop with some huge magnets would induce enough voltage to breifly change the sensed frequency, but they probably just average that shit out anyway.

Hi Bogan - you are quite correct about inductance being used for traffic light vehicle detection now days (apologies). It is true that figure of 8 loops were once used to count fast moving magnetic objects (eg cars) but this is not the case here. (I did some checking up.)

Interestingly an inductive loop operating at around 100 Hz is used, and its inductance is decreased by the presence of any conductive material within its field. This is how this same technique can be used by treasure hunters on beaches to locate gold coins, aluminium etc. Ferro magnetic materials are not necessary, any conductor will work. Eddy currents are induced in the conductor & it acts a bit like a shorted transformer turn to reduce inductance.

My big bike has a duralium frame (plus some steel) which is detected quite well by traffic lights. It is my little largely plastic scooter which has a few problems presumably becuse it has only a small centrally located lump of conductive material.
Thanks for that ...

I really need one now

My 600 doesn't like to activate lights, is it something to do with the only steel being the axles, crank, cams, valves and rods?
The GN is just a joke...

The quick answer is probably yes!
The most easily detected thing (once again I acknowledge my earlier mistake about magnets) would be a large conductive ring, eg a hula hoop made of aluminium or other conductor. The duralium cage frame of my ZZR is probably quite good for a motorcycle. The bottom pressed steel floor of a car obviously works well too.

Perhaps I can start a new trend - hula hoops for bikes! :

Not sure how we could turn a hula hoop for bikes in to a Chick Magnet, but it sounds reasonable.
Is it the bike or the attracted chics that are loopy??

Could be me. All my ex chics were well loopy.
