hello
any help would be great
My son has a spanish bike with a ybr125 engine in it,as you all know this engine is air cooled.
He ran the bike low on oil,i mean low less than a 1/4 of a litre,which has brought on a tapping from top end
tappets are fine,cam and bearings are ok,i have put oil straight on to the inlet tappet,ran the bike and the noise
has gone,but 10 minutes later,it returned,so it can only be that when he ran low on oil,he brought some crap up
from the sump..
So my now for my question...is there anyway of clearing the blockage without sripping the head off,can i use a
oil flush or would that do more damage,,
