OK this will bring a smile to a lot of faces.
i am the proud owner of a CB750 sohc (approx 1970) chop,
from what Ive been told the has been bored out to 836.
now its time for an oil change, (this is when you all start to laugh) either I'm blind, stupid or something, but i cant seem to find much out about how to do it.
the Haynes manual is a total waste of time, looked many times , each time drawing a blank.
Ive looked on the internet but as of yet not found a decent explanation.
any dos or donts would be of a great help , I'm used to working on V8 s normally, bikes are  a new thing to me.
thanks

 ;) Start up bike and let it run for about 10 minutes, shut it off and put it on the center stand.start with the oil tank first.loosen the filler cap. Have a drain pan ready and remove the plug.After the tank is drained, replace and tighten the plug. Proceed on to the oil sump plug and drain the oil from there. Again, replace and tighten the plug.remove the oil filter housing. there is a thin washer between the oil filter element and the spring. This likes to stick to the filter and before you know it, you've thrown it away. crank the engine over a few times with the kick starter to get out the last remaining oil in the engine. Take a good look at what's in the bottom of the filter, as any bits of metal might be a warning that something's on it's way out. it might be worthwhile to drop the oil sump to give it a good cleaning and clean the oil pump gauze while the sump is off. Apply a bit of clean oil to the oil filter O-ring.With the bolt back in place, reassemble the oil filter housing with the spring first, then the washer and finally the new filter. Replace the filter onto the engine,do not to overtighten the bolt.Fill the oil tank with about three and a half pints of oil, the oil level will drop to its proper level when the engine is started. press the starter or kick it over a few times with the emergency stop switch off to circulate the oil into the empty filter housing before running the engine. After doing this, fire up the bike and the oil light goes out in a few seconds.if not your in trouble  :o check for oil leaks and oil level ;)

As much as OEM oil filters are, they are still better quality than a lot of pattern filters that I have seen. I bought some cheap ones for my CB550 & under a sustained speed one split & caused a blockage in the oil flow. This seriously damaged the cam bearings & followers. Morris Oils do some reasonably priced mineral oil for the older bikes...not much point in using semi-synthetic.

My thin washer between the oil filter element and the spring is missing: is it a crucial part, if so where can I precure one or is it a standard washer?

Slowly getting on with my commissioning  ;)
