By the time you think and worry about getting the engine out sideways, you could of popped the wheels off, dropped the forks and removed the swing arm 
Yeah fair one, suppose trying to save time in this way might be a false economy. With I hadn’t just fitted the new chain with roger link on. It’s a 100 link chain and the adjusters are almost all the way out so I can’t get it off the sprockets by moving the wheel forward. Maybe I can just pop the front sprocket off to get it off that way

 Maybe this is the solution!

Anyone got any experience pulling an engine out the side with either an engine crane or engine hoist? Can buy them second hand pretty cheap or even hire one for a day for £20.

Before fitting any engine you have to check that the engine turns freely via the kick start and every gear can be selected under load.
There are many problems if the oil pressure is not building up on a 750. It can even be a 0' ring at the wrong size or missing.
Well live and learn. I tested all the gears whilst turning the crankshaft but didn’t think about the kick start. Still hoping that maybe the clutch cover is interfering as it was quite a tight fit getting it over the kickstart spindle

I would not try running it until you have addressed the kick start problem, the cog wheel on the kick start can lock and then lock the engine via the clutch.
Drat. I’ll Remove the clutch cover bits in case that’s causing something to bind tomorrow, if I have no luck.. well I guess I better gear up to get the lump out agin  Last time I stripped it down to the frame and later it on its side. Are there any methods to remove the engine from a complete bike?

I crossed over your posting there.
With the Vaseline, it'll only cause a vacuum and not go through the pump generally. You need to make sure the oil is getting from tank via oil line to pump entrance, if so then the Vaseline will pull the oil through with the vac it causes but if you spin the pump first before oil is available then it may not work.
When I removed the pump just now oil poured out of the inlet oil way from the tank so it’s definitely got a supply that side. I’ll have a look if the oil filter is wet tomorrow. Really don’t want to remove the engine again right now, to the point where I’d rather run it without a kickstart for a while before addressing it!

Dropped the oil pump back out seems it was binding in a certain position and sticking tight. Took it apart and on the inner rotors the little dent marks were on opposite sides, flipped one of them round and it’s now smooth. Packed the rotors and oil ways full of Vaseline, reassembled and no cigar. Little disappointing as I was sure I had it!
As suggested above I’ve poured some oil into the tappets to avoid any damage but there’s graphogen in there so it will probably have been fine anyway.
When I packed the rotors with Vaseline I expected it to be pushing/sucking in Vaseline as I rotated the pump back and forth but it didn’t really - is this correct?

Charged the battery up today and gave it a good spin up off the starter but no pressure. Had a look in the tappet covers and it’s still dry up there. Going to have to do the Vaseline trick tomorrow.
Got the front brake set up, the actual bleeding was easy, the difficult part was tightening the fittings without the hoses kinking up.
None the wiser with the kickstart. Hoping that when I’ve got oil pressure it will all get the lube it needs and magically start working

I’m hoping it’s something to do with the clutch cover stopping the Kickstarter returning properly as this has been the issue for at least one bloke on the US site. Fingers crossed I haven’t assembled the kickstart spring incorrectly!

Took the old girl up to see bryanj on Saturday who helped me with the wiring  He also knocked me up some braided hoses for the front end. Today I’ve fitted the chain, plumbed in the oil tank, fitted the exhaust, prepped the oil pump by submerging it in oil and turning it back and forth until no air bubbles come out. Filled her up with oil and have been kicking her over with the killswitch on to try and get the oil pressure light to go out. After 60 or so kicks no luck yet. The kickstart seems to have a limited range of movement and it’s not springing back up. Could this be due to dry internals? Hopefully it isn’t anything assembled incorrectly! This pic shows the end of the range on the Kickstart.

There should only be vapour coming out, unless you have a problem. The 500 does just exit to atmosphere just in front of the rear wheel
Nice one bud. Anyone know where I can get a shorter speedo cable from? I’m not using the front fender (will use a brace) so It’s now got a lot of slack where it loops backwards, ideally I’ll just run it up the inside of the fork lower instead so could do with it being 20-30cm shorter

Been thinking about the breather hose that comes from the back of the cylinder head thismorning, originally it connected to the air box but now that’s gone I need another solution.
I could just route it down to the ground so anything coming out of it would go overboard - but on a well running bike should anything be coming out of it outside of vapour? You can get fancy little filters to go on the end of the breathe hose which you can attach anywhere but in my head I’m imagining it becoming sodden with oil over time and causing a mess?

Did my 750 by the laying the engine on the side method on my own and it was easy. Prop the side of the top end up with some blocks of wood so it sits level on its side, you can get the bolts through as the bottom end sticks out further than the frame so you can get your hand in easily to put the bits on

Any baffles in there ? 
Looks nice, is it a good fit onto the cyl head? The headers and collector look nicely formed, what make is it, or is it made up from various pipes?
It has a stainless steel perforated core but it’s pretty open.  Headers are from MAC and end can is From Cone Engineering, both were Picked up when I was overseas and had 20kg baggage allowance!

not wanting to get into anything serious with the bike today I’ve made up the 4 into 1 exhaust. The reverse cone is 12 inches long and was 0.7mm too small to slide over the collector (according to my micrometer!). Cut a slit in it, lubed it up with copper slip and banged it on with a rubber mallet. The bracket is just for show as it won’t be coming off again without a fight!
