    Hello Minh
    Nice work I like your rocker arms but just my suggestion : on the push rods you have some brass parts
    //probably for setting valve clearance // do it as light as possible because heavy push rods
    decrease engine performance and rise stress on cam shaft lobes.

    Thanks for the praises !
    Now, I can say: "start a new project with a design " and it could be a 2-cylinder engine with a water radiator before doing V4..., I need to learn more...

    Nice job, love the V twin sound, was this totally freelance or ideas copied from something else.
    Would love drawings or doodles if available. What ignition,plugs etc?

    Hi IC-man !
    It is freelance
    I combine the available things, gears, ... and the things I can do
    With plugs, I make it
    I can draw it before doing it, but I don't know how to do it?
    I don't have much experience in machining and knowledge like some of the members here, I try to think of it as two engines but combine it with a 90-degree angle, with the camshaft I do the 4th but it seems it is incorrect, every part of it has some in the trash
