Ran my 196 after installing a flat top piston. It is not in the bike yet but so far has nice throttle response and sounds meaner. Total mod was under $30 after a new quart of oil, a $10 flat top piston and all new gaskets. I reused the wrist pin and rings and it worked out great. You can feel the compression when you start it. I also received some stamped 1.2 rockers today in the mail. Motor now has larger filter, filed jet, BSP rod, champion rocker cover and some 22 LB springs for future mods. I still need to install the tach as I chopped the return spring a little to gain top end and although governor is kicking in it is doing it very high now. I am thinking around 4,800 RPM by my top speed. Going to see if screwing the throttle stop screw in will lower the governor speed. Going to run motor as is before doing further mods.
