OK, so I went ahead and installed the ESI Chunky grips with WD40 no problemo. The bar plugs, however, were a pita to install and won’t stay flush with the bar so they look like crap. I think I made a mistake getting the Chunky instead of the Extra Chunky, not because they are not soft enough, but because the overall diameter is too small. They are a bit smaller OD than the Ourys that I removed, which I found were just about right, although they were not at all comfortable. The first photo I uploaded shows the old Ourys, and the last two show the ESI Chunky grips.
