I have just completed a full rebuild on my XR 250 R and I kicked it over to make sure the timing was correct, once the enigine was up to heat I check the oil level (I had already put 1.7 litres in) and there was no oil on the dip stick. I put the remainder of the bottle into the frame (I am now up to 2 litres of oil!) and after idleing the bike for 90secs or so I checked the dipstick again and it only just barley put a dot on the end of the dip stick. I am very dubious about putting any more oil in. Can anyone help? Oh and there are no leaks I left it overnight with a white sheet underneath.
