Have 'em out, don't notice anything irregular. Thinking on end of cheap insurance while I have the engine open. I don't have the tooling (recommended min. 6000 psi with a radius crimping anvil) to complete a proper roller bearing replacement so I would have to buy new tappets all together.
It should roll and move side to side, but if you can rotate it any (looking head on into the roller), then you need new ones.
Check with your local MC or even a smaller job shop, labor wouldn't be that much to put new bearings in. A LOT less than new lifters.
Otherwise, I'm sure you can find someone with a hydraulic press (ie, bottle jack press) to swedge the end of the shaft for you. These engines were made to be rebuilt in a fricken corn field with broken glass and cigarette butts...at least, that's how I'm doing mine.
Mine are Jims; I don't think they had that press requirement.
I recall making a little press from a c-clamp to press the axles in, as well as a tool to mushroom the ends. I think I went as far as to stake the axles too.
