What casting number should they have?
The options are:
1. 45300
2. 40170
3. 40100 (I'm almost certain that this is MX125A)
4. Something else again
The US parts list show the barrel as having a part number 453-blah-blah, but that doesn't automatically mean that the casting number is 453...
I've also been told that the US bikes had a re-boreable cylinder, rather than the chrome bore of the Australian/European delivered bikes?
Any help?
