I would imagine they just cleaned up the cam slightly as they didn't tout any HP increase. Slight changes on lift, duration, etc may have been done to smooth out the engine.Correct.
And the 961 was made originally to use those same lifters.
My point is, if they now use something that is different in dimensions and requires machine work or bushings to fit properly, I’m not interested in tearing into my bikes just to see if it fits, all because their tight lipped.
If they went from a cheap China made lifter to a comp cams or quality brand I’m on board for that.
As stated above the oil pump(volume mostly and pressure) won't handle a performance lifter
