Zongshen RX3 carbureted version mods & repairs

thanks Kat, so by using smaller bolts to mount engine it gave it enough slop between the 3 engine mounting bracket holes to relieve the stress on the rocker cover . I never would of though of that. I wonder if you could go in with a round file an elongate the mounting bracket holes above the rocker cover ???? to accomplish same thing? Never heard of this problem before here, rj

PS: rereading wilsoncheah's post above, do they fix it by leaving the top mounting bolt out altogether??? That can't be good.
Do you have a link I could read about this problem in Malaysa?

yeah, I reckon that elongating the holes would work

To be honest, when I first read about their oil leak problem I didn't think that tension on the top mounting would cause this, I figured that a crack in the casing would be more likely to occur from excessive tension.

In my opinion its more likely to just be a bad gasket seal.

That said, it wouldn't hurt to undo the top engine mounting bracket to see if it is under stress and whilst Its off, tweaking the bolts on the top casing to make sure they are tight.
