Stalling on Gear Down

[Canuck]

Hey Guys,

Back with another "Kerfuffle" on the GZ...

Ive been out riding around and have noticed when i gear down at a stop light, stop sign etc the Gz seems to lose its Idle and stalls while i clutch in .

I know my sweet spot and am just wondering if this could be a result of the Valve Clearance? It has been around 10,000 kms since it was last done.

A new plug has been installed however i don't remember applying Oil to the stem of the plug as the manual says to do.. O_o
whoops..

Though i don't think this is a problem im just curious if anyone has had this exact problem and I am wondering what you did to fix it.

I haven't had a real solid Idle for a long time now. but it seems to have gotten worse lately..
9 times out of 10 ill clutch in...gear down and POOF.. shuts down and i have to restart while holding up traffic behind. Gets pretty irritating

ALSO i made sure to check the idle jet adjustment at 2.5 turns to the left and its where it should be.
94 octane with a bit of Sea Foam

could it be the main adjustment for the clutch is to tight and maybe I am inadvertently going way past the sweet spot and causing it to "flood"
I'm not to sure if it is Flooding or what flooding entails but it sounds like a viable option for this problem...

Anyone?

Hey Canuck, read my thread on "Stalling during first fifteen minutes." Your symptoms are nearly identical to mine, but I don't know if the cuase is the same. Possible culprits include:

1) Carb
2) Emissions (if you have them)
3) Valves
4) Air Filter

I over filled mine with oil shortly before my problems worsened. Not sure if this is related or not.

I think your basic problem is the engine is not running smoothly enough and when it drops to idle it quits. Does it get better after th engine is warmed up? You can cover the problem up by boosting the idle, but I don't think you will like the high idle (and it will kill your gas mileage.) It may also make the problem get worse over time. I fixed mine by taking it to a dealer (three) times and just insisting they fix it. I'm not sure what ultimately fixed it, but it did get fixed.

For the record, my plug was fine, and my air filter was in pretty good shape. I'm not confident enough to look at the carb or valves, and I don't even know where the emissions stuff is. I had only about 3000 miles on the bike when I took it in to get this problem looked at.

funny Alan i ended up overfilling mine to..

opened the oil filter box once and let some out. put it back on ran the bike and opened it again and i was back to the top again

same issues..

Maybe some of the other guys can speculate what the likely side effects of overfilling are. I think Easy or Patrick mentioned a few at one point, buti don't remember what they were specificallly. I can tell you there was no oil on my plug, in fact, te plug was pretty clean (and properly gapped) when I pulled it.

Othere theories included overfilling my gas tank (didn't even know this was possible, never mind bad) and crap in the gas tank. Because a lot of my difficulties settled down after the bike was warmed up, logic tells me the problem was in the carburetor. I figure if it was air filter, or valves, or gas tank, or even emissions, well, it would probably persist after the engine warmed up.

Have you been reading the other threads on here lately? If not, why not?
There are at least 2 of them regarding stalling and rough idle. I just posted an update to one of them a few hours ago.

Is 94 octane = regular in Canada? If not, switch. Seafoam is NOT necessary in every tank and if you are not actually measuring, "a bit" might be too much.

Your terminology regarding the clutch makes no sense. The clutch has nothing to do with flooding. The clutch cable should have a little slack; if there is too much slack, it might be dragging. What is a "sweet spot" ?

You do know there is an adjustment for idle speed, right?

Back to the top of WHAT ??

Based on your (lack of) understanding about how an engine works, I think you need to take it to the shop........soon. :roll:

The "Sweet Spot" was something my motorcycle instructors taught us.

"Pinching the dragon and putting it to sleep".

Pinching the dragon meant the sweet spot where you pull in the clutch and shift gears to allow smooth transmission..

Putting to sleep meant when you pull in the clutch handle and the bike is running but without throttle or engine control.

Sorry if my terms are off, tried my best to explain my problem as i saw it.

same issues..

Do you mean the plate that holds the oil filter in it's own little housing on the right side of the engine ?? There will always be oil in there if things are working properly. Pull the engine oil drain plug and drain a bunch out into a clean pan. Top up as needed to bring the level up to full mark with the bike in a verticle position(not leaned over on the stand). Start using regular 87 octane gas and see how it runs. And don't put any additives in the gas tank. Should be better if all else is okay. Now, about that valve adjustment, give it some serious thought.

Sorry to disagree, but when I put fuel additive in the tank (at 10,000 km) I noticed a difference straight away - much smoother, particularly at low revs. The bottle says to use it every 4000 km,which I shall definitely do. The bottle holds 365 ml, & from the instructions, I worked out that I needed 75 ml to a tankful of petrol.

Interesting instructor you had there!

I think you misunderstood something.

When shifting, one doesn't look for a "sweet spot" with the clutch; you pull it in ALL THE WAY. After the shift is done, you let it out.......all the way; smoothly, not abrupt but not worrying about any "sweet spots" either.

The "sweet spot" occurs at a standing start. It is the spot where the clutch just starts to engage. You need to be able to sense that spot and control it for a smooth start.
Unless you are doing something really strange, it really has no impact on subsequent shifting.
