Its supposed to be 12 ft pds which is 144 inch pounds using a ten inch long, quarter inch drive torque wrench...That was in the manual I posted on here for you to read and apply...It's on page 15 and reads as follows:
Take a rag and wipe underneath the exhaust port where the pipe flange is attached...If it is wet and blackish, you have a leak on the exhaust gasket and it is blowing the oil that you are seeing thats wetting the front mount section.
Only if you left that cup and a half of oil still in the crankcase you mentioned a few pages ago...I had repeated told you that you only use a few drops of oil on each of the crank bearings as well as using just a light coating of oil on the inside of the cylinder applied with your fingers.
That is a real possibilty if you didn't double nut each stud in order to seat those four cylider studs all the way down before placing the jug over it when doing the final assembly.
These are all questions that you should have asked BEFORE doing the final assembly, not after the fact.
Do you remember a few pages ago when I mentioned this to you???
