Hello,

I bought a 750 SF, 1971 model and my first post will be questions about motor oil.

How much engine oil shall be at the oil change? When I'll check the oil level dipstick must be screwed down or lie loose when I check the level?

My English is not the best, but you know what I meant  :D

This is my first Laverda and runs fine but needs new paint and crom. First I want to get it registered and run with it so that I learn to know it before I start the restauration. Have driven it a few feet and shaking quite a bit. Was afraid my teeth would fall out ???

Hello Arne.
Get hold of a manual. A "green book" is on eBay at the moment.
Oil is close to 3 litres. Top mark with dipstick sitting at start of
threads but not screwed in. Good semi-synth mc oil is fine.
There are a couple of us SF folk near Oslo if you need a hand.
 
you beat me to it Arne !
I just did my first oil change, with sieve removal, 77' SF3.After allowing it to drain for a good 30 minutes and with my canister of exactly 3.0 litres fresh oil began to fill up, as i approached 2,5 litres I thought I would check the level and was surprised to find that the dipstick registered 1-2 mm above the upper mark. The dipstick is sitting on top of the case thread. Exact measurement was 2.6 litres. I then measured what had come out, exactly 2.5 litres. Rechecking after a run and drain time shows that the level is still just above the upper mark. So where is the other 500ml ? Does one need to perfom any rocking or tipping of the bike or indeed removal from the centre stand ? Should the primary case be removed in order to get the oil fully out ?
Should i be concerned by CLEMs report that some oils don't get on with each other and cause "fluff" to develop ?
I saw somewhere recently (USA i think) someone that offered replacement filters using proper filtering media which itself was pleated, anyone know of these, i lost the link, does anybody use anything like this, indeed is it likely to be of much use with short oil change cycles ? What oil change intervals are people here using ? the bike will not be used on a track but it will be used.

Not sure if the twins are similar to early triple,in mine the primary chain case holds a good 500cc.It levels off through small openings between the main case so there is usually a fair bit left in there.It can be drained via the primary chain adjuster if your keen.Wait to have this confirmed from other twin owners.
 
And just to be safe measure your dipstick (fnar fnar). A previous owner had substitued a triple dipstick on my SF - they look the same but the triple dipstick is about 15mm longer (205 for the SF, 220 for the triple).
 
Just changed mine today, 20W 50 mineral although I also use semi synthetic (but not fully synthetic). Same oil as I use in my Mirage. The twin (SF1) took 3 litres and was just below the upper level on the dipstick after resting it on the thread (not screwed down). Did about 100 miles this evening and running well :-)
 
Our boffins can clarify but as I understand a filtter should be
after (pressure side) of a pump, never the suction side. I have
mounted a round speaker magnet in the base of my strainer which
holds on to any ferrous shit to help out the oil slingers. The
primary case on a twin does not trap much oil but as said rocking
from side to side off the stand has me with about 2.8ltr on change.
 
Hello again,

Thanks for the great help to a new Laverda owner:-). I figured it was so that the oil dipstick was not going down, but lying loose on top. I filled the 2.8L oil up to the max mark and'll check next time I change the oil how much I get in return.

I used Biltema 15W-40 semi synthetic oil today I could not get mineral oil at my local seller. Are these motors sensitive to the type of oil a user?  I just bought the bike and wanted a quick oil change so I knew that it was fresh.

Expect the current bad mc oil they sell is much better than what the best oil they sold 40 years ago. A change oil often and waiting to run hard the engine oil is hot then it will be fine (I hope:-)). The engine is tight and no oil leakage.

Re Tippie, thanks for your help and have found manual on ebay and I'll order. I live in Stavanger and it is well 500km between us, but I'm going in the area with Laverdaen so we could made ​​a run. Always nice to meet other Laverda owners.

Regards
 
Arne. Not really sensitive but wet clutches generally need mc spec oil.
Most mc shop have semi-synthetic.
Good idea you have to change it regularly.
Lysebotn next summer?

Hello again,

Thanks for the tip, but it is Biltema motorcycle oil I use and expect that good to my old 750.

Ok, Lyseboten next summer. It's a long time since I've driven there and it's a great ride.
