Hi

I'm just getting my 750sf2 back on the road after a long layoff (10+years) and was wondering if there was anything specific to this model that i should do before i finally press the go button..

so far I have drained the oil that was put in when it was stored and refilled through the tappet covers to make sure they got a coating, I have also sprayed into the chamber with a wd40 type thing and let that sit for a few days, and now I have just turned it over by hand a few times and am dieing to stick the new battery on and turn it over on the motor to build up the oil pressure before i try it with some fuel and spark plugs but wanted to see if there is anything else I should attend to first?

while I'm here can I ask any UK members where they get there oil from as I have searched all over town for some 20w50 mineral and am pulling my hair out (not that I have any to waste these days)

thanks very much

John
 
First:
-New oil
-New battery
-Check valve play
-Check compression
-Put oil over the camshaft and rockers
-oil in the combustion chamber
-Turn few times by hand
-Check ignition time and play
-Ultrasoon clean carburetors, new seals, check for worn parts and correct working order
-New petrol!
-Start engine!

First to ride:
-Put in second gear and push the bike without clutch (sticky clutch release)
-Check brakes and old tires
 
This Laverda 750 SF2 also not run/ride for 10 Years, after 2000Euro`s and a lot of work in good running condition.

John,

Empty your workshop oil squirter through the valve inspection caps, all over what you see of the cams and followers rather than turn the engine over with the starter.  This will drain the battery needlessly and the low revs that the starter manages won't build up much oil pressure anyway, will only get a tiny dribble to the head at best.  Oil flow will kick in at slightly higher revs, no pressure to shout about, either!

Put on your toughest outfit and stroll into your local H-D dealer, he's got barrels of 20W50 in stock! :D

Morris' V-Twin 20/50 is a favourite of many -

Available online too.
HTH,

X2 Peit's recommendations - Ensure the Cam Followers are Lubricated and Lash Set Plus the Carb Manifold Gaskets are Sealing - Points will probably have to be Polished with 600 Grit.

I don't know if you will like to hear the following but if the Mill has never been dissembled the Head Gasket may be Deteriorating and Main Seals  probably Rotted and ready to fall apart.

So be prepared for a Tear down & hope you catch it before you Blow a Piston. I'm a Mechanic; but the 750 Twin is Easy & a Joy to Work on - Even for the Novice.

Holed Piston or not: You can refresh the Engine with New Gaskets, Hone the Cylinders, Install new Rings, touch up the Valves, Polish the Cam Followers and install new Valve Springs.

As far as Motor Oil goes: I prefer Industrial Grade Dino 15w40 CI-4 Plus with approx 1500ppm ZDDP to protect the Cam Followers.

Been there done that. Good LUCK ;o)  
 
thanks for all you replies

the motor had the works done 2000 mile ago -re-con crank, all new chains etc- at Miura Engineering, so i hope it is ok.

I'm after a new oil filter plate now as well but will start a new thread for that.

cheers John
 
Hi John,

Short of ordering your oil on the internet you could try Halfords Classic 20w50. My local branch stocks it, so I guess it's generally available. Best of luck with the awakening of your Laverda, I'm slowly working my way round mine with a hope to using it this summer.

Great stuff, noise in the garage.
It sounds like a full carb strip and clean is in order. A good idea as has been mentioned is check the inlet manifolds, o-rings and spacers in case you are sucking false air. If it doesn?t rattle or bang you could be soon ready to get it onto the road.
I finally get my SF2 out from its winter hibernation tomorrow.
