Heavy Breather

[skiddusmarkus]

Is it normal for a valver to breathe wuite heavily when the oil cap is off?I cant smel petrol but worried it could be the rings on their way out.

it all depends wot u mean by heavy! mine does "a bit" on idle (stops once u pick the revs up), and thats with new rings and honing.

u could do a compression test if ur worried...

if it runs/goes ok then dont worry about a bit of vapour out of the filler cap when running. if it evers starts to feel underpowered etc then thats when you worry and look into it.
