Stalling during first fifteen minutes

Good for you; bad for me.

New air filter didn't fix mine. Off to drain the old gas out and run some cleaner through.....and check the idle mixture screw to be sure it hasn't fallen out.
:skull:

Assuming your carb is clean as a whistle, you still have the mysterious "emissions", and... the valves. If you get it fixed let us know what the magic was. I wasn't too hopeful on the air filter - mine wasn't pristine, but it was pretty clean.

It probably isn't really all that clean after sitting all winter.....

I don't have that "stuff"; only you guys on the left coast........

I'd like to say it can't be the valves but not ruling anything out at the moment.

Mine is a couple of years older than yours and the air filter looked light brown; it was due for a change.

It's GOTTA be the carb. or the gas.........right ?? :whistle: :popcorn:

Carb makes the most sense to me. Back in my cab driving days, most of my aggravation came from crappy carburetion - typically on "Chrysler" products. I also discovered that a Toyota Tercel and a Chevy Nova can be air starved at high altitudes (used to put a clothes pin in to hold the air flap open.)

I think I'm pretty much back to where I was last year.
I drained the carb.
I reset the idle mixture screw....about 3 turns out.
I tightened the boots on BOTH sides of the carb. Both were loose.
I think that last one was the major culprit.

NOW......the remaining question IS: Does anybody have a GZ where the idle does NOT vary a lot from cold to hot?? When cold (after turning off the choke) mine has an idle speed that borders on being too LOW. After it heats up good, it borders on being too FAST.
It has been pretty much like that since I got it (2nd owner). It is somewhat annoying.

In cold weather, I choke mine about half way, leave the driveway, then take the choke off while in 2nd or 3rd gear.
My first stop sign is 1/4 mile away, never had any problem.

Hot or cold is always the same rpm.

My bike has always been ridden hard and put up wet....

I got no complaints about it.

This was very pronounced in mine before Mission Motorsports finally fixed it. There is still some of this effect, but it is much reduced. If you want, I can give the number for mission motorsports and you couldtalk to "Mike" who personally supervised the work on mine after I made a stink about the first two (failed) attempts. Mine is more than noticeably improved. I only need half choke to start it, and after a two, three minutes, no choke at all. The idle is lower that I had it before and it hasn't stalled once since I got it back. I'm pretty damn happy with the way it's running.

I agree that the idle drift is very annoying. Especially when you know it is not necessary.

How much is too much? I'm not convinced that it is not normal.

Some people notice things like that and some don't. JWR says he has no noticeable change; you still have some. Mine now starts fine and runs fine and, if I leave the idle adjustment in that one exact spot, it doesn't stall or race and the idle speed doesn't hunt around.......it just steadilly increases over a half hour or so of more or less steady riding until it is several hundred RPMs higher than it started out. It has always been that way.

Guess we need more votes. Please call 1-800-my gz sucks :shocked:

I don't have any tach measuring capability, so I'm going by "feel." My idle stays pretty low even after warming up, possibly lower than you might have even recommended. Because the engine is so tinny sounding, I wouldn't call it a Thump-Thump so much as a Tink-tink-tink-tink. But it ain't stalling and that's fine with me.

To be blunt, after riding a big displacement bike, it's difficult for me to view the GZ as a serious motorcycle. I know by many measures it is, but, the thing is so small and works so hard to go 55 that I've come to see it as a sort of an eccentric novelty. It gets me back and forth to work just fine, and with hardly any fuel, and it's light as a feather, (and cheap to insure!) but I think the idea of doing a multi-state trip with it requires a certain degree of dogged eccentricity.

Yes, but mine is a Spanish spec. I'm convinced that the problem is the politically correct, tree hugger, bullshit, that is currently affecting every facet of everyday life.
I'm 62. I've smoked, eaten fatty food, drunk my share of beer & whisky,Lived life to the full, & I'm still fine. I object to being told what to do by adolescent, homo, save the whale, vegetarian, assholes.
Over here the air is monitored in every city, & the results published, so that even the "bleeding hearts" can have a say, & the results show that the air is fine, without having to go to the extremes that seem to prevail in America (& to some extent in England) The Spanish way is "hey man, do your own thing)
What I've read on this site about the extra bits on American bikes makes me wonder why the "touchy, feely" brain dead morons weren't put down at birth. Thing have happened over the millenniums, & we're still here. The emission controls are just a way of ensuring that the government kowtow to the easily led, so that they get re-elected.

Phew ............ Glad to get that off my chest, but that's the way I feel!
