As far as I know it was never laid down.. So options are? Rebuild? Find a used motor? Trade it in?
I am guessing laid down, or some other oil pressure related abuse. The 1198 is a third generation motor and as a street bike, very reliable. Of course, racing/wrecking them is a different scenario.
Buying a used motor, intelligently, is an effective solution, as the rebuild on yours, depending on the condition of the crank, cases, etc. will be huge to my wallet.
I have successfully bought motors off Ebay. but you have to be smart. The last one I bought was guaranteed by the seller, upon delivery I pulled the oil filter, drain out 2 ounces of oil, sent the oil to Blackstone Labs in Indiana for analysis, ($25),
boom!! test/analysis was perfect, no wear, no problems, actually the motor appeared, physically, to be very low mileage. Put it in the frame, fitted all the parts, boom! perfect. Started right up, ran like new, etc.etc. If you own the right tools the change is an easy, but thoughtful event. Actually quite a pleasure to accomplish. Also bought another motor, a aircooled 1100 evo motor, also an unqualified success. So yes, smart shopping on ebay, as well as other used avenues are well worth the time and energy, but again, proceed with utmost caution, there is a lot of junk out there and,.... and bad advice.
