Just bought a 1992 907ie... now it won't start

[englishstiv]

Okay reading your post discounting all the stuff about the lights etc (If you are starting don't have any of your indicators or riding lights in the ON position please).

It would appear that you are attempting to ride the bike with the choke open (ON).


Please supply a picture if possible with the choke in it's position when the bike is idling at 2 - 2500 rpm.

The engine will need to warm up for about 5 minutes ( dependent on local weather conditions )

The engine will not run with the choke operating for very long as it will be over fueling and you will flood the engine with fuel which will stop the spark plugs from working.

If you have been riding with the choke on you may of also fouled the plugs up with carbon - DON'T WORRY ABOUT THIS AT THE MOMENT.

Concentrate on getting the start up procedure correct.

Go to this link and then look at page 70 study the picture of the choke position, -

IF you can print the book out it will actually answer a lot of the questions you are asking on here as a new owner.

otherwise

I would advise also just reading this book through as well as it will explain a little more about the bike.

Please confirm if you are now using the choke correctly....?

As Englishstiv has said you were riding the bike with the choke on.
Use the choke when starting the bike from cold, push the lever away from you, past the first 'click' and press the starter. Once the motors running for a few seconds then ease the choke lever towards you until the bike is running at about 1500 revs. Let the motor warm up for a minute or two, maybe until the temp gauge starts to rise. Regulate the revs with the choke as it gets warmer. Your bike is now good to ride, put the choke all the way back to you(clockwise looking from the bar end). Control the revs with the throttle if its still a bit cold. When the temperature is 1/3 to 1/2 up the gauge, the motor shoud tickover at about 1000 revs.
This ritual is required for most Italian,British and some jap bikes, Not so necessary in warmer climates tho, All part of their 'character'.

This is where the choke is turned on:

(lever all the way forwards, or turned counter clockwise, viewing bike from kickstand side)



This is where the choke is turned off:

(lever turned clockwise (right from side), 1 click clockwise means less choke?, and 2 clicks is completely off)

So the bike will idle with the choke on at around 2000-3000 usually. Why does this fluctuate? It seems to start at 2000 and go to 2500, or sometimes start at 3000 and not move much, and when I first got it it would be higher I believe, like start at 3000 and then rise higher, to 4000 or so. Should it be rising higher than 500 now, which means it is warming up and I can turn the choke down?


-Now when I try to turn choke off, even after warming up 5 min and riding for a few minutes, the engine will die if I don't rev it at the stop.
-I learned about using the choke at the motorcycle course, but on those old Japanese bikes we used (not F.I.), after being turned on for just 2 minutes you could turn off the choke, and after revving once or twice, it would never die down again.

I guess that is why car alarms go off since I was driving with choke on...

Please read the manual it does explain your question.

If the 907 is anything similar to the ST series, the choke on a fuel injected bike is just a throttle stop, and doesn't really choke the motor at all. All of the cold motor choking is done by the computer. So if he is riding with the choke on, its just that it has a high idle.

If it dies when the choke is put all the way to close, then the idle is set too low.

Cheers, Phil

Oh, so when the throttle stop is on (forward position), then that just makes it the same as if you were slightly turning the throttle? Does this mean that it is not bad to keep it in the on position? It will just keep the rpm higher, or is it still better to keep it off after it warms up?

I just had a first real ride in a long time. It started at 2000, after 2 minutes went to 3500 and stayed there. I then put it in the middle position and it stayed at 1100. But it sounded weird, like it was about to die, but it never did die. I almost dropped it when my girlfriend decided to jump off when I was turning to park...haha

The only thing was that in the middle and off position there was absolutely no noticeable difference, it stayed at 1100.


Thanks guys. I guess this is like it is supposed to be? I decided to keep this bike unless someone offers me 2x what I paid for it.

It`s good the problem was sitting on the bike and not the bike itself. If indeed you had very high idle with choke/fast idle off as you had written a few times before there would have been something seriously wrong.
As you say the brakes and clutch are now ok but the oil does still foam I`d suggest you proceed as planned and change oil and filter. Then check the lights and tire pressure, lube the chain, get fresh gas, put on your safety gear (means incl. gloves and no jeans, no sneakers) and then go for a nice long ride (60mls or more). Don`t take any twisty mountain roads but some open ones and if it is the highway. Somewhere where you can ride moretheless at constant speeds so you can get used to the bike and the bike has a chance to run for a while at it`s normal temperature and to burn clean the spark plugs which may have fouled by often just running at idle.
If after that and some following tours the engine still stalls at idle you need to get that adjusted. The reason the engine may need a higher idle could be the high comp pistons. (Note btw that with hicomp pistons you shouldn`t run the original spark plugs but "colder" ones and that you have to use gas with min 95 better 98-100 octane rating)

What is a bit worrying is that you have little to none riding experience and you already ride around with your girlfriend (which, and I`m guessing here has no other safety gear than a helmet ?). All you should take along on your first tours is some money and your cell phone.

as per avatar...sometimes I can only scratch my head, and have a bit of a laugh

[ducinthebay]

Uh, yeah. Keep the girl off the bike for at least a year.

... and that`s why it`s on ebay again. You definetely won`t sell that bike, specially not in that conition and with that video. It`s all banged up, no fairings on and the sound of the high idle is terrible.

haha, maybe i'll get lucky when it gets warmer
