You are surely confusing those dimensions and intigers with those of Maggies coffin? 'Presuming she was buried deep wearing her favourite '90's power shoulder pads' that is.
Or else 'get on yer bike'

Should that be 64 x 128?

No, he means 64mm stroke with 120mm long rod but I do understand that some motors use dbl stroke length for rod length... in the same way that some motors use same stroke as bore diameter, however, there are so many exceptions to the rule that I don't actually think it is any sort of rule. You know, the sort of rule that says that you don't need to eat the whole tube of Pringles once you've opened it, which is another rules to be broken

Yes, the BGM cranks do have big end shims.

Those 62mm cranks from AF which are £180 are the same cranks as the ones advertised in the second post in this topic which are £199. Are scooterotica ones" blueprinted" or something?

You are nearly right. The ones i sell are split, the big end is machined so you dont have to scoop the casing, and then re-built and trued.
The AF one, if you'd bother to read the text in the listing, is not pre-machined.
