Up for sale is a perfect set of Keihin CR special carbs for a GS500. These retail at about 589.00

200.00

No air filters included.

What size?

Not sure of the size. The only markings on them say CR special, for race use only, and made in Japan.

I can only assume they are universal, they are for a GS500.

Pics?

Why dont you just measure the outlet ID?

I will get pics up very soon, and a measurment.

please see my pm

Got your PM.

Here are some pics

I will bump this for you hatch.

One fun fact about keihins is they are super easy to re jet. See that nice big bolt on the bottom of the floats? Under those is the mains. Makes it super easy to change out main jets.

I love these, well I have FCR's on my monster, I don't know the difference, but they have been fantastic on that bike.  I think the difference between the FCR's and the CR's, is that mine are true flatslides, where the throttle cable connects to the slides, and has no butterflies. great throttle response, most likely with these too.

$200 is a good price. I had a set of 33mm CR's like these (but I do not know what size these are) and regret selling them for $275.

Would this be a bolt one mod?

Ahh,

Looking at the pictures I see they are flat slides. They don't have a butterfly. These carbs would greatly improve throttle response. There is no waiting for vacuum to actuate the slides open. The slides are directly connected to your right wrist. much more responsive.

These are as bolt on as stock carbs, the only question is if their size is any bigger than stock, to see if they would fit in the stock carb boots that go on the head. Bump for nice add-on at a good price.

Sorry guys, I don't have a metric ruler at home. I'm stealing one from work tonight.

How do I go  about measuring these beasts? Outside rim to the outside rim?

I hate metric, I do know that the motor on my bike has always been stock, except for the 1mm overbore.

Measure the inside diameter of the outlet.

No actually they are round slides, which while they do not offer the response of a flat slide, they wear much better and last a lot longer. 

Inlet seems to measure 3.8 mm

They are now on the egay
