What is proper way to start GV250
« on: August 23, 2017, 07:56:33 AM »

I have been facing problem of F1 light. Do you know anything about proper way to start?
I have been doing:

1- Ignition key ON
2- Kill switch ON (F1 comes ON and stay)
3- Start the engine (F1 goes OFF)

Can it be the reason of having F1 light issue?

Is it the proper way?:
1- Kill switch ON
2- Ignition ON (F1 comes ON and goes OFF after 3.sec.)
3- Start the engine

Should it be in exact order? Does it matter?

Here's what that owner's manual says.  It does talk about the FI light.
"Before attempting to start the engine make sure :
The is equipped with the side stand ignition interlock system.
1. If the transmission is in neutral, you can start the engine regardless of
clutch lever and side stand.
2. If the transmission is not in neutral, you can only start the engine with
pulling in clutch lever and side stand up.
Make sure that the side stand ignition interlock system is working properly
before riding.
WARNING
always comes on the position lamp, meter lamp, tail lamp and
license plate lamp when the ignition switch is turned to the “ON” position.

CAUTION
 The following happens :
the “FI” check lamp “ ” ① on the instrument panel should comes on.
This lamp should go out after three seconds whenever the ignition switch is
set to “ON” position.
If this lamp does not come on when the ignition switch is set to “ON” position or
fails to go out after three seconds whenever the ignition switch is set to
“ON” position, contact an authorized Hyosung dealer.

CAUTION
After three seconds whenever the ignition switch is set to “ON” position,
“FI” check lamp “ ” ① must goes out. If this lamp stays on or brinks
during normal operation, it means that the fuel injection system is not
operating correctly. Stop the engine immediately and contact an
authorized Hyosung dealer. Do not use the motorcycle with disabled fuel
injection system, in order to avoid damaging the engine components.
CAUTION
Avoid pressing the starter switch when the engine is running, or
starting motor damage."

First things first. It is a FI light not a F1 light. FI = Fuel Injection.

Next, stop using the Big Red Kill switch. That is there as an emergency kill feature and acts by grounding your coils just like the side stand switch. Stop doing this or you will shorten the lifespan of your coils.
Use the d@mn ignition key like you are supposed to!

Thirdly, when you turn on the key you are meant to wait for 3 seconds for the FI light to extinguish. During the first 3 seconds you will hear the whining sound of the fuel pump as it pressurises the fuel lines to the fuel injectors. Once the FI light has gone out then you hit the starter button.

Once the engine has started the only time you will get the FI light is when there is a problem. If you stall the bike the FI light remains on until you cycle the ignition key on-off.

Yep, second vote for not using the red button - that's what I was told by a Suzuki dealer....emergency only.

Switch the key on, wait for everything on dash to set up, rev counter bounces round the dial and back and fuel pump whirrs, then push the start button.  That's it!

Anything other than engine start must mean there is a problem somewhere.......

possibly the stupidest "myth" ive ever heard. utter utter bullcrud. shows a complete lack of understanding of basic electrical fundamentals.

it does not "short the coils".

There is generally only two ways the kill circuits for motorcycles operate:

  • The first method is to have a contactor that allows the ignition circuit to be energised, breaking that contact via the "kill switch" results in cutting the power to the ignition system. Honda and yamaha often use this. This is how hyosung do it.
  • The second method is to send the low voltage signal impulse (from the CDI/ECU) that would normally pass through the coils primary winding and then to ground, and send it directly to ground, negating any induction in the coils secondary (high voltage) windings. sure, this does make both sides of the coils primary become ground. At this point it can no longer work as a circuit as power can not flow through it.  Thus no possibility damage could occur.



now the anti-knowledge you have stuck in your head is probably based on the arcane method used by lawnmowers of old, where by the high voltage (HT) secondary windings were shorted to ground. In this instance it is actually a short circuit : power induced in the secondary windings has no where to escape as it is now a closed circuit. as a result all it can do is create heat in the windings. This over time can cause damage to the coil.
to my knowledge, there is no modern motor-vehicle that uses this method of stopping an engine by shorting the HT circuit of the coils.


Go read a wiring diagram and see how its done. Hyosung themselves call it a "engine stop" switch. No mention of emergency use only. Hyosung use the FIRST method i described.

I'm not going to argue how it works, I'll just repeat that a Suzuki dealer told me not to use it to stop the engine, and that it is for emergency use, like if you wanted to stop the engine while moving (say, at speed with a jammed throttle) without taking your hand off the bars.......

I had an emergency cut off on my kit car, like most racing cars have, but again that was for emergency engine cut off......

Ignition key is all you have in a car, surely the same thing on a bike is all you need to use??

Anyway, hopefully this is unrelated to your problem!!  ::)

Well when I did my learners course.. twice! (Never progressed onto provisional before my Ls expired).. both times they tought us that the way to stop a bike is killswitch then key (unless the owners manual explicitly states otherwise).

I can understand wear on the switch as a reason for not using it though.

When I learned, we just had to ride around the block, ride slowly beside the examiner for a short distance and do an emergency stop!!  Ahhh, 1969, life was simpler then...... no expensive bike gear..... no helmet!!

My Lambretta LI125 wasn't even fitted with an ignition key, just a kickstart, a stop button and a steering lock!! ;D

I remember someone saying that if you use the kickstand to kill the ignition, that it grounds the coils and that it's a contributing reason as to why Hyo coils die prematurely. Was it Hylife, maybe?

sidestand circuit uses the same "engne stop" circuit as the switch via a sidestand relay ... ;)  the relay allows power to flow to the engine stop switch. If the sidestand is down and engine put in gear it cuts power feed to ignition circuit (which is exactly what happens with the "kill" switch)
