oil leak

I believe that my engine is leaking oil out of the left side engine cover. i have looked on kawasaki.com and gotten the part number and i cant find anyone else with one. i have an 84 ZN1100 LTD. can someone help me. i want it cheaper than what ill have to pay at kawasaki. ive looked on bike bandit and dennis kirk.

well I know that Jeff Saunders has these for the 900's and the 1000's...maybe He can help You.
These little grommets are usually the cause(unless it is a gasket)
