Next time an older car passes by, see if you can tell if it's running rich or lean. You don't have to go and stick your nose in the exhaust
P.S. (edit). I'm glad you made that comment, W.W... My 'don't ride just after doing this' statement was meant to be a lighthearted warning, but I don't think it was made strong enough.

I thought it was funny

Welcome and happy riding

Whats up guys. Today I turned the screw back out .5 turns. Right where the manual and most "RESPECTED" riders have said and its running great. Before it was really sluggish on the bottom end. Just got back from a ride tonite. Its about 70degrees F here. Really nice out. My idle still seems a little low. I dont have a tach yet but Im guessing somewhere around 800 now. Idle adjust screw is so darn iffy. Adjust and its great, ride and its crap. Maybe not crap, but not what I want to hear.

Be sure you have the idle mixture set to were you get best Idle between lean & rich.
Make sure bike is completly warmed up before setting the idle,it should be around 1200 to 1300 rpm.Check out some videos on u-tube to get a idea of proper speed at idle.
:2tup: :lol:

That's about the only complaint I had with my GZ.

After cleaner in the gas, lube'ing all the cables and throttle parts and adjusting the mixture......I finally gave up and decided that the final idle speed was just going to be "variable".

I ended up setting mine when it was thoroughly warm but not really hot.

That way, I could turn the choke completely off in a reasonable amount of time without it stalling.......but then on a really HOT summer day after a long ride, it would idle a bit high. I just learned to live with it.......except for my road trips.....when I just couldn't stand it and had to tweek it back down just a bit.

I suspect it was still "in range" but I just wasn't comfortable with it.

Since carburetors control air volume, but the fuel/air ratio is a matter of air density, and since air density is determined by humidity, altitude, and air temperature, could any of those three elements (humidity, altitude, temperature) have changed significantly between tune-ups?

Sure, could have.

In my experience, it changes from morning to afternoon.
Mostly that it just runs better on the lean mixture when HOT.......I think.

I also suspect that the "European" models and those with the jet changes and needle shim mods won't notice it nearly so much.

And that is one of the main reasons FI is so sweet. No more messing around. The TU 250 would be a nice ride with it's FI.

Um, after I adjusted the valves recently, I noticed it seemed to idle much more regularly - so, cb3 have you checked the valves ?
