165FMM engine

I've not removed the rocker cover, but am thinking it might be possible that my engine is a 165 & 167 cobbled together? The 165fmm (CB250D-G) is listed as a camshaft upward but mine does not have the rocker cover to house the camshaft & chain. So, I bet you are correct. My bottom end is stamped 165FMM.

Here is the link for the 165FMM: http://www.zse.cc/productsdetail.asp...=368&CateID=43
