Vm id help

[savage454]

My bike came with a set of mikuni vm round slides on them. I'm not as familiar with them as I am the stock mikunis. I looked at the post with id'ing these and didn't see anything with my markings. Do they make a 31mm vm? One carb has just 31 imprinted on the intake side and the other carb just has 3, then what looks to be a sideways D to the right and slightly higher, and an x. The only other marking is MKA by the choke plunger. Also they are both left hand carbs. The only problem I see is lifting the choke lever on the right hand one. It's too the inside. Unless theres something I don't know. Thanks

Got a pic? Don't think they made a 31mm unless it was some oddball size for a snow mobile or something.

This is the marking on the other carb... Although they are both left hand carbs. Hope you can see it. It's 3DX with the D slightly higher.

Thanks to figure8 for pic help

Try measuring the O.D. of the air filter side of the carbs. The outer diameter of a vm34 is 57mm, which is a common vm carb used of xs650's.

No the only markings are the ones I posted except one that says MKA, mikuni and Japan

I'm at work tonight. I'll bring home my calipers and measure the id of the intake side

Then, next would be to measure the ID of the throat, in millimeters...

 

[savage454]

Okay, got it. Do I also need to measure the slide? Or just those id's?

 

[TwoManyXS1Bs]

Sure, measure the slide OD. And post a pic of the front of the choke boss, and the float region, with float (s).

Edit: Here's the Mikuni dimensions chart.
