I just drained all the oil from the tank and the oil pan, then removed and replaced the oil filter. I kicked a couple of times as the clymer manual sugests. I assumed all 3.7 Quarts had been drained. I then pour 3 Quarts of oil into the tank. Low and behold there is WAY too much oil in there. Am I missing something? Am I a complete boob? Can someone shed some light on what I may have done wrong or what step I have skipped?

Its a 76 750 F.

3 quarts is normal on my 750F. Start and run the engine until the level in the oil tank starts to go down and it should be at the full mark on the dipstick. If not, just top it up. In my experience the 3.7qts is very optimistic.

I think that .7 qt was meant as backup for the miles between oil changes when we all lose oil from the head gasket.

Bob Wessner · « **Reply #4 on:** July 08, 2006, 05:57:51 PM »

I'm going to figure this difference out if it kills me.

I did just have a rare thought. When I do an oil change, I do the tank first, then put the plug back in and move on to the pan and filter. When kicking it over to get the last of the oil out, is some oil from the pump going back up to the tank? Should I be leaving the tank plug out also when kicking it over?

Ponder, ponder. $:-\$

Nah, you're just a complete boob mate, ha ha! Seriously though, unless you drop the sump pan off, drain the oil filter, oil tank, and kick that engine over until there is nothing hiding in the head, transmission etc, you'll never get 3.7 quarts into it. There's just too much residual hiding in low spots. if you strip the engine entirely, then you'll get it all in, no worries! Cheers, Terry.

So how are some getting 3.7 qts in theirs?

Hate to burst your bubble, Bob- but I just proved Terry right! I just got around 3.7 quarts into the 750 I was just working on... however, every oil gallery had been drained and cleaned out in the motor, so it was completely "dry".

That's cheating.

I'm under the impression some are getting 3.7 in on a routine oil change.

This IS curious. I've changed a LOT of oil on a LOT of CB750s, and all of them easily accepted the 3.7 qts. The K0 actually held 4.0 qts, first 4-5 months of production (bigger, square-er oil tank at the top was the reason, then Honda changed the manual and the dipstick). I usually run 4.0 qts. in my K2, doesn't cause any problems.

The sequence I've always used: drain tank first, then crankcase and filter housing at the same time, then remove filter. On reinstall, kick over 40-50 times until the oil light goes out (maybe add another few electric-start seconds for good luck), then start & run 1-2 minutes, stop and check level.

Good grief, 40-50 times?! Hmm, I will give this routine a try next time and see. Where is that extra quart in my bike?

Terry, did you steal it?

Of course, it this it true, I've probably never had really clean oil after a change if there's a quart of dirty left in there.

That's it men, check your oil an hour after an oil change and it looks pretty murky if there was all that stuff still lurking in your cases. I just bought the BMW I've been yakking about, now my mate (the PO) did an oil and filter change with new synthetic (as he's been using in it since almost new) last month and it's already as black as, so I'm guessing he didn't get all the old stuff out........... I just ordered a new oil/filter change kit, and I'll be making sure I get the bulk of the old stuff out this time. Cheers, Terry.

I'm crying thinking about my right leg, and how it's going to feel in a few months time when I get to do my first oil change..

I can see mondayitis coming on....

Terry, why haven't you changed the oil yet - too busy riding

i know it's not a Honda, but i wish you could post a couple of photos and keep us posted on the work, Terry - as you know I'm hatching a plot to move into one of these myself...

There's another twist that doesn't fit. After about 400 miles it still looks pretty clean. Hmmm. Oh well.

I will mate, as soon as I get off this thing and go for a ride so there's some decent background scenery, and not just my driveway, ha ha! I'll post 'em when i get back tonight. Cheers, Terry.

Speaking of oil change, about what mileage should I be changing my oil and filter in a '73 CB350F?

What are the consequences of overfilling the oil reservoir?
a) catastrophic global meltdown
b) minor levels of urban carnage
c) a bit less dinosaur decay available for the next generation
d) no biggie

Depends on by how much. Just a wee bit, no biggie probably. More than that, an oil version of Lake Erie on your garage floor.

You can take it back down to the correct level with a turkey baster. Guess how I know.

that's the last time you sneak the turkey baster out of the kitchen, i'll bet! i'm surprised you're still alive to tell the tale...
