Also. Looking at your picture. You could do with some fresh brake fluid!

Well if you do get stuck there are a couple people in the bay area that are kind of good at getting them to run well...... ;)

Yep...did all that. Made my own carb sync too.
See my post in the Tech area.
Shes runs great!

I may adjust the pilot's 1/4 turn in -with all the California stuff removed and capped she may be rich -only a tad though. With PAIR removed and blocked sometimes I will get a pop once in a while on deceleration from a high rpm.
Would coming in 1/8 to a 1/4 on the pilot screws take care of this?
The manual says 2 1/2 turns out on 49 state bikes and 3 turns out on CA bikes.

She's so close it's hard for me to know. The previous owner installed a jet kit and he doesn't know what he used. So, I called the shop where it was done and they can't remember which one it was. They think dynojet.

I will pull the plugs tomorrow.

Where can I get that tool?

+1 on the brake fluid change . I am waiting for Galfer lines though.

EDIT:

INITIAL OPENING of Pilot screw:
2 3/4 turns for 49 State
3 turns for Ca models.

Ya. I am just a tad rich after capping the purve control valve intake to the carbs- from the the carbon can. The bike is used to sucking a little air and fuel vapor into a small carb. port while running.
It's very close though. Will know when I pull plugs.

Mixture screw adjustment. Really the only easy way to make mixture screw adjustments is to remove the carbs some what? ie:pull from carb boots, tilt to one side and make adjustment. Once you have done it a few times (like you will on owning this bike) you can do it very quickly.
I will say one thing, most people tend to jet these bikes to rich! not to lean.

I would pull the carbs and see whats inside first?

Also don't forget to adjust TPS!

After installing 48 pilot jets (my main jets are stock, with stock needles shimmed .020"), I initially adjusted the pilot screws 2 3/4 out. It ran fine at sea level, but wouldn't idle above 2000 feet. So I set them at 2 1/2 out, and it runs perfectly up to 6000 feet, with very occasional carb farts and idle stalls at sea level.

A carb disassembly and cleaning about once a year helps a lot as well, even with good gas.

A Craftsman 18mm spark plug socket fits into the plug recess great. My Snap-on, which I've had for 30 years, is a tight fit.

Thanks...but I am not about to touch my carbs just yet without thoroughly understanding them.

There are 3circuits:

1) Idle
2) Pilot
3) Mains

I would like to know how the needles and shims and holes in the slides and pilot and main jets all work in relation to one another.

I am wondering if I can just buy the tool and not have to take the carbs out to adjust mixture?

There's a lot to go wrong if I start to monkey with it- while its so close to a perfect tune.

Time to do some more research on the forums.

Like I said....there are people in your area that actually do understand how a carb really works..... ;)

So what part of the bay area are you located in?

Pretty far South in San Luis Obispo area.

Ah..this is what I may need:

It has that d shaped bit for these Keihins.

EDIT:

Ah..The power of the internet.
This is a great article on carbs.

Does it ring true on our 48mm Keihins?
