A quick tutorial I did on how to change the oil on my buddies 1980 Honda CB 750. This same info can be transferred to just about any motorcycle except instead of an oil filter housing there will just be a screw on oil filter.
Great bike. I have owned one since since '89. But you're making a mistake when you check the oil. Do not screw dipstick down. For the accurate reading allow it to rest on the ledge without screwing it down. . Then check oil level on the stick. That's as per service manual.
Dude! You left the DS washer on the old oil filter! You can see it is still on the old filter at 1:19 on your video. It goes between the spring and the filter so the spring has a metal surface to push against and doesn't puncture the rubber on the center of the filter cartridge. They often stick to the old filter like yours did and then people throw them away.
It's a shame about the dirt & oil all over that engine, 'cause I friggin' love your Mix-&-Match DOHC-4 bike, with the 'F-type peg brackets on a 'K bike, or chrome fender tank & seat from a 'K on the 'F-bike, or whatever the heck it is - It's cool.
It's part # 11 called a "Seat" on the fiche, but it's just a washer with a big hole for the filter bolt to go through. See the 1980 cb750f parts fiche: 11 SEAT 15414-300-000 001 $2.49
You dont screw it all the way down and then back out to check dip stick, you literally remove wipe, dip, remove, check. Doing otherwise will mean you are running with low oil all the time.
So after following these instructions, my filter case is leaking from the top where the case meets the engine. The O-ring is in place, and the casing is tightened down pretty tight. Any ideas?
Sorry, but you are making a mistake - read the manual. The right amount of oil is not measured when the dipstick is screwed in. Insert the dipstick without screwing your in and read the oil level
