I’ve been looking everywhere for different options for a portable hones for the 100cc engines (KA100 & VLR). I heard about the Sunnen JN-95 but the range is 2"-2.6" (50,8-66 mm) and the engine bores of the 100’s are 48.2mm. So what portable hone are people using? If any
Ammco 3950 is what I went with and it’s worked well for me.
I use a lisle 16000 Hone.
It was cheap and although it needs to set up carefully to make sure the stones are parallel, it works well. I couldn’t justify the price of a Sunnen with the number of engines I rebuild.
