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
