Just so we're clear on it....in=lean out=rich? And at what increments would you recommend turning them?

Clint,
That is correct for most of the carbs on these Hondas, it does depend on the carbs though. Some carbs have been used that meter the air bleed rather than the fuel circuit, but that's another story.
I like to make 1/4 turn increments, so you don't end up with it richer than it needs to be. Most of the manuals recommend 1/2 turn increments, but with that you could end up 3/8 of a turn too rich. Not a big problem, but in a situation where you have to idle for a long period, like a traffic jam, you could foul your plugs. I'm a bit anal when it comes to A/F ratio, I like to get it as close as possible because at best, the carburetor just works in averages. In other words, at a certain throttle opening the A/F ratio may be perfect. Open or close that throttle an eighth of an inch and your mixture is not perfect anymore. Fuel injection is much more precise in the metering department.

Thanks for the information. One of the bike shops told me that the bike had sat tooo long and that the carbs needed cleaning out. One of the jets was partly plugged. I will listen more for the pop. If it continues, I will see about the carb adjustment. Also going to pick up some B-12 Chemtoll today and flush the system. I have been told that gas here in Portland should be at close to $3.00 a gallon for reg. by Memorial Day so I plan to have my bike on the road often... SICK FROM THESE GAS PRICES

There's nothing wrong with your plugs, they fired didn't they?

Yeah it ran fine after that. I haven't had any problems or hesitation. I'm sure it was just a one-off situation.

Dude, I got a 1973 Ducati running with a simple carb cleaning and some fresh gas, so the nice reliable Honda should be fine. These things are damned near unkillable...

I was reading through a few of these older threads, and this one caught my eye.
At the AutoZone where I work, we recommend and sell alot of "Lucas Fuel Treatment"
I've used the B-12 and have nothing bad to say about it, but I can tell you the Lucas is more potent than the B-12. It's just something I thought I'd share with all of you, either one will clean your fuel systems, I just wanted to let you know of another choice.

The Lucas is just a little more, unless you get the big $8 bottle that has enough in it for about 10 treatments, then it's ALOT less than any treatment on the market. Those 10 treatments are for 16-20 gallon tanks too.

First thing I'd check frankly is my exhaust seals. If your bike has been sitting a long time, or if it's been jostled, the crush gaskets under the head pipes may need to be re-torqued. They go to 17lbs/ft and then take the pilot screws out to about 3.5 turns. Adjust your idle circuit with the idle screw a bit to avoid the pops.

I seriously doubt jetting is an issue unless you've changed the pipes significantly, added a K+N filter, or modded the air intake.
