If it's the same as the next

If it's the same as the next gen R52, they are 0.004"/0.01mm for all.

Sorry for the slip, you have

Sorry for the slip, you have it right. 0.004"/0.1mm. Unlike the later OHV models with light metal pushrods, the sidevalve bikes only have steel followers, so they don't grow very much under heat, really just about the same as the iron cylinder, so they don't need a big gap that they can grow into.
