    Hello people again!
    So, i saw pictures of bikes that had holes on the clutch cover and on the other cover of the other side.
    It makes any difference?
    Like cooling?
    Thanks!

    Don't put any holes in those covers. They keep dirt and moisture out of critical moving parts. There is absolutely no cooling benefit.
    I'm not sure where you saw pictures of the covers with holes but they were not on the bikes built by experienced builders.

    Like 2door said no cooling is needed
    and the gears inside that cover are the noisiest part of the engine
    so holes will make that worse.

    I have seen the holey cover pics of bikes and they were art bikes.
    Made more for the look than function.

    uhhh, i put some holes in my clutch cover. a few small ones drilled on the side in the front and rear, hoping to cool down my clutch by passing airflow through it.

    i dunno if it helped.

    BUT the bike is totally modified and the stock clutch pucks don't work with the power, and after trying every adjustment, etc i could think of, i drilled the holes.

    now i'm just gonna get some real friction material for the pucks.

    The OP was talking about swiss cheesing the clutch cover, magneto and
    sprocket cover.
    It looks cool, I have some pics saved somewhere.....looka like a GP bike.

    You are using Chinese rubber tire sidewall clutch pads. It is some kind of
    modern day miracle that it even works!

    The red round clutch pads are a better material, maybe?
