You may not see oil about with tappet covers off but if you rev it oil should splash over everything in sight outside of rocker cover to give many happy cleaning hours
Perfect, thank you, that's probably my main question for now answered. It's certainly not splashing when it's revved. I've got a couple of bike friendly Liqui Moly engine cleaners coming and I've a deck of Oil Filters from DS Spares. That's my first port of call, after that, if it's engine out and stripping to clean the oil galleries, well, I've already inventoried and boxed all the spares for an advert...put it that way.

Hi Chris, we have something in common as we both seem to be F2 people plus I've only very recently joined. Aberdeens weather challenges the bravery on the motorcyclist doesn't it ?
Yes. Yes it does! Pyjamas under my jeans and three jumpers, all helps! You gotten yours running??

Oh, yes…welcome Chris.👍
Interesting steed you have there. That carburettor modification is very interesting….is it a novel solution?
Murrays Carbs in South Carolina I believe. My standard carbs had been to a couple of experienced places and couldn't get them to seal well, or get the floats to properly stop the overflows to leak fuel over the garage. So, a trim down to just the two, hoping it was easier to balance and less to clean up. Plus Pay in Three, sold. They get in touch and ask about the bike, what exhaust etc is fitted and jet it and test it accordingly. Sadly, I've not had mine started to properly test them.

Sorry Chris, but was the question?
Apologies for the delay in replying, the question... If I remove the tappet covers off the top of the motor, should I see evidence of the oil circulating? I see it in the tank, there's a return flow to it, but at the top with the tappet covers off, I don't see anything.

Thank you all, I have the search function open, see if I can get an answer to my first question, the decider for carrying on or throwing in the towel.

Evening Folks!
I like to follow rules, so I'll introduce myself as Chris. I've had a 1978 CB750 for perhaps 10 years or so now I think!? In that time, I've ridden it perhaps one mile! It was purchased in boxes and parts though the engine was whole. I bid on it on eBay, not really thinking I'd win, or knowing much about them. Back then, I just knew they made cool café racers!
Over the years as I've had spare cash, I've tried to get stuff for it. Pic should be attached, if I've done it correctly! Original seat but re foamed and covered. Replica tank beaten out of flat sheet aluminium when mine was rotten. Carpy 4 into 1 as it didn't have an exhaust. It's got a set of Murrays carbs, so they're correctly jetted two into 2 branch manifolds. I gave up on the original carbs. Realised I dislike carbs. I've gotten it back from a garage after retrofitting electronic ignition and it's running better than it ever has.
I've joined to ask a few tech questions and see if I'm going to be able to finish this off, or if it's going to be put up for sale. See how the answers to the questions go!
Nice to join and say hi, especially after years of browsing the site to see others peoples questions, see if they'd answer mine.
