Yeah the 38mm carbs are far from rare on the 2011's. TBH there are probably more 38mm carbs out there than 36mm ones. It was like Spain ran out of carbs and there was going to be a delay or shortage of 38mm's so they back filled with the 36mm. I can only think of a few people who have reported having 36mm ones, but the thing is if you think you're jetting for a 38 and find out you have a 36 it does make a significant difference so it pays to know which one you have.

I'm think the cap would be interchangable between 36 and 38 but am not certain. I can't see why they would have got mixed up but anythings possible.

Some also have a plastic spacer between the carb reed block (i think.. or air boot?) and others don't. It seems to be an area of variation. I think most 300's came with a #7 slide. Some with the notch, some without. Not sure about the 250s. Then theres the actual reed block spacer aswell.
