Does anyone have a wiring schematic available for an early SF 0. With Bosch headlight, electrics, and Nippon Denso clocks. The clocks have additional wires to the Smiths clocks as they have warning lights.
 
For me, SF is the original 1970/71 bike with camel back tank, replaced by 72 model SF with either CEV or Lucas switch gear. When the big valve engine came out, we had the series SF1-2-3.
In the book La Diva, the 72 SF is referred to as second series SF which is also explicit enough.

It would be nice to drop the SF0 denomination.

Then please offer another means of differentiating between the early camel-back tank/Smiths instruments and later tank/ND instrument versions of the SF. Model years and first registration dates often cause mix-ups, as they rarely coincide.

SF
72 (model) SF
SF1
SF2
SF3
 
you can see why the uninitiated think that
SF1 means one disc,
SF2 means two discs
SF3 means three discs,
all of that is VERY WRONG
(just in case someone reads this at a later date eg 2055

really it should have been
SF
SF2 (72 SF)
SF3 (73 SF1)
SF4 (twin front discs wire wheels as SF2)
SF5 (cast wheels triple discs, as SF3)
(the last digit almost gives you the year of manufacture)

then Pieros Zane engined cafe racer (that was not carried on with AFAIK, one sold in Australia and one his own) would be SF6

Best is to do it yourself, there's not much to it. The hardest is starting. Plenty of tutorials on internet.
Wolfgang used to make them on order excepting the sub looms, instruments, switches etc which is what most loom makers propose.

Since one must presume that your location is a UK postcode, doesn't make much sense to a Malaysian, try http://www.motorcyclewiringspecialists.co.uk/services.html

They did a loom for my 3C. Nicely made but £140 and it's only about 6 wires. One of the reasons it's preferable to do it yourself.
Sub looms apart, your SF main loom is probably 3 or 4 wires. To which you add sub looms and ignition loom, 2 wires.

You see that ground from the starter relay to frame - I highly suggest you wire it to ground through the tranny neutral switch or you will suffer a starter clutch failure and explode the starter as there is NO Protection to prevent the starter from engaging when the bike is in gear if you ever accidentally hit the starter button while the engine is running - Starter Clutch dogs be damned.

Meaning you can only engage the starter in neutral and on later wiring circuits only when the clutch lever is depressed.

Definite Breganzie 750 SF issue ;o(

Dellortoman - Have you ever owned a 1970 Breganzie Laverda 750 SF !!!

It is a specific wiring fault with them foot ball (rugger ball for you Aussies) Bosch head lamps.

Take HEED. Other then that FIX best to weld or bolt the back onto the back of the of the starter clutch so it don't rattle and jam the dogs.

It will save you a very expensive starter motor and starter clutch assembly ;o)

Ron your just one of thousands of owners that have/do own 750s and you seem the only one to have had a problem with your starter clutch blowing the starter motor. If it was an issue why hasn't there been thousands of starters blown. I have owned 4 SF models over the last 47 years and never had that problem and yes I've hit the starter many times while the engine was running. You failed to service your starter clutch when it need it and the results was a blown starter. Your myth has been debunked by many owners and experts.
And how many kms did you do on your 750? I bet no where near the hundreds of thousands many 750 owners have done on their 750s me included.
