I have a 97 KLF300 4x4 that I just recently got. After I did the oil and filter change (just about no oil in it when I got it). I noticed a puddle of oil forming rear the back of the bike after about a week of sitting. It's not a fast leak, but it's a steady leak. Today I investigated it, found the oil to be coming from the boot that covers the rear drive/cv shaft. I took the clamps off that and slid it back to find out which end it was coming from, either the rear diff or the bevel housing. After awhile I noticed it coming from the smaller boot that covers the joint on the front of the shaft. The boot is not ripped nor does it have any holes in it. it is leaking out of the smaller end of the boot. Now my question is.......Should there be oil in the boot? I always though cv joints had grease in them. How would fresh engine oil get to the boot? How would I go about fixing this problem? Thanks for the help in advance. I've been racking my brain on this one, been looking through the service manual and looking at schematics online and can't find the answer.
