ZZR 600 E12, Oil in air filter

11-23-2011, 03:31 AM
Hi, looking for a bit more help.

Further to a bit more investigation over the weekend, to this poor runing issue. I removed the tank and the air box cover only to find the filter sodend with oil in places and little poddles of oil sat in the bottom of the air box. The crank case breather pipe looks dry so cant understand how the oil has got there. I feel this may be the poor running issue, the engine starved of air but think there may be a bigger underlying issue.

Any advise anyone?

Can't see how the oil would get up there other than the crankcase breather, maybe the crankcase was overfilled at one point...? Check the oil level, try a new air filter and go from there.
