Idling Issue

[Shammua]

First of all I did several searches and didn't see anything similar to what is going on for me.

Just got the bike back on the road now, I took it to the shop just like I planned and ended up getting them to rebuild the carb. since it had sat for so long. Anyway with that being said here is what the bike is doing.

1. Cold start it will idle for a minute fine then idle real high afterwards and wont stop until I take off
2. When Sitting still it might idle regular but if I turn the handle bar one way or the other it will start idling real high and wont stop unless I turn the handle bars straight again. (I checked cable tensions when turning the handle bars and didn't see a change)
3. It will sound like it's idling fine then just die.

Thanks for the input and can't wait for the replies.

When you start the bike and it starts to rev you need to turn the choke off a little at a time to keep the bike from revving to high intill It is warm.Check your choke cable and plunger to be sure it's not binding anywere.When the idle increases when you turn the bars it is a sure sign that you have a cable routed wrong,or sticking.

What blaine said.

The choke cable is real easy to get off, remove at the carb and WD-40 the plunger.

It takes a while to really warm up, mine does that too during the first 10-15 minutes. Once it's hot, it should idle fine.

Also, the general impression I have from your post is that your cables need lubrication.
It's just five of them, four from the handlebars, plus the brake cable down below.
(come to think of it, I never lubed the speedometer cable...).

Regular motor oil will do. I use a match stick, put a drop on the inner cable, move it a bit. Repeat like 15-20 times.
There exists a handy cable lube trick involving a plastic bag and some tape around the bag/outer cable, but I've never done that.

Edit: according to the manual, idling issues could be caused by:
1) clogged or loose pilot jet.
2) air leaking from carburetor joint.
3) clogged pilot outlet port.
4) clogged bypass port
5) starter plunger not fully closed.
Assuming the shop carb cleaning took care of points 1), 3) and 4), it could be 2) or 5).

check for an air leak by spraying carb cleaner at the carb area just to make sure air isnt gettin in where it shouldnt

Well this GZ is carborated which means cold starts are always little rough but once warm is fine, but normally if its a jetting problems just need little fine tuning or to be cleaned out due too sitting too long and gas has jelled over in carb

I have figured out what the issue is. It was me the whole time.... It makes the bike run a LOT better if you actually turn the choke off and only use it if you have the need. :P lol I feel like such an idiot for something so simple... lol

It would be different if I was a mechanical noob, but instead I am only a noob with bikes. For those that don't know, old cars had chokes too and you had to do the same thing... lol Oh well.

Even if you had the choke on, when it should have been off, it shouldn't have done the above. You might need to check the routing of the cable to make sure it isn't getting pulled when you turn the bars. :)

Nope once I put the choke like it was supposed to all symptoms went away. The bike runs perfect now. :)
