lifan engine gasket help

[andyj621]

hi there, i have a 125cc lifan motor that needs a base gasket, it is suppozed to be a 54mm piston with the engine number being 1P54FMI, however when i ordered a new piston for it it was too big, and the barrel actually measures 52mm (give or take a little) i do not desperately need a new piston, i was doing it simply because it doesnt feel as fresh as it did when it was new, but the base gasket tore on the way off, can anyone point me in the right direction and possibly enlighten me on why it says 54mm on the cases and doesnt appear to be on the barrel! it is an oval oil hole too.

normaly if its where i think it is its the cc of your engine, but you can make your own gasket using a cereal box and a hammer look it up on youtube

you should always replace your gaskets when doin a rebuild.
