I think modifiedman on this site has or gets the Lifan motors with the 14cc head.
Yes the Lifan GK65-S comes with the 14cc heads on a 196. The Lifan 168F with 22 heads but are 5 bolt valve covers
as were the GK65 is a 4 bolt. also stout racing has them too.as for the 14 on the 160 yes they came with both 14 and
18.the champions did come with 18 but now are 22.
If this is the one your talking about , Mine has the 22cc head...http://www.stoutracingengines.com/bp/bp.jpg
Dished piston, here is a picture of one.I use them to build my modified motors out of hold up well
I also have built them for guys running stock too.I cant say about the 212 have not run one but
have had my hands on them.If you want one that packs a good punch and makes a little over
10 hp out of the box with header and carb jet change is the 196 cc champion engine.
you can ask Sneaks about this one.
