I was at work over the weekend and was changing crank seals on an Invader 440 I've had sitting for awhile. Unfortunately, I got distracted by customer phone calls right after applying honda bond to the crankcase and forgot to oil the bearings. The crankcase is assembled but the heads are still off. Is there anyway to oil them without taking the crankcase apart again? Also the manual didn't say what type of oil to use, what should I use?
