1973 750 SF Throttle cables - UK or the dimensions so I can make my own...

[Mr Vegetable Trousers]

Does anyone in UK stock these or can anyone tell me what the internal and external lengths are?

Im not sure that the one with my project (yes I know there should be two!) is correct. It seems too short,

 

[Paul Marx]

Which model exactly is your bike?
1973 model would be SF1, late 73 would be SF2.
Lucas or ND switchgear?
What handlebars have you got on it?
A photo would be lovely.

SF1 Lucas switches with ND clocks.
The cable outers don’t stay in place at the throttle end.

So, SF1.
The bars, likely identical to SF2,3.

Original Tomaselli twin cable throttle, from memory had a rubber cover over the cables that would have helped hold them in place. It is quite easy to fabricate simple cables like this if you have a decent soldering iron, I have a Venhill kit for nylon lined cable. Start at the carb end and it is easy to work out the overall length at the handlebar end.

Tell the Conwires blokes that, it took 3 goes for an out-of-stock Pantah throttle cable. I supplied a sketch but that didn't help.

Tomaselli twin pull aren't standard SFC excepted.
Otherwise all big twin throttle cables are triple pull since 1 cable, 1 splitter, then 2.
This place is worth a few Venhills minus tax.

The throttle in the movie looks exactly like that which came on SF1 imported to Australia at any rate.
Vince, the Conwires mob should have given me a call. I successfully instructed my 17 year old son over the phone (from the middle of the North Sea) how to solder up a new throttle cable for his 125 Honda, rocket science.

 

[Mr Vegetable Trousers]

Thanks everybody, My first attempt at making new ones was not 100% sucessful, I need more practice is all! I have also ordered another of the rubber cable holders for the throttle end of things my exisiting (original??) one is perished and it appears to be an important part of keeping both cables in place.

From memory Venhill cables for a non California Guzzi T3 are 105mm with 88mm of free inner. The twist grip and carbs are basically the same as the SF. (The inner could do with 5mm more but it’s no use telling Venhill who make lovely cables but are difficult to deal with! They also have a habit of packaging Cali length cables in normal length packaging!)
I buy from Wemoto who supply Venhill cables. If you think the length is ok they may be worth trying. If you buy some and they don’t work I’ll buy them off you.

My 71 model year has a twin cable set up, and in the La Diva 750 book a number of photos show this cable set up. I know it has been said some of these bikes displayed were preproduction.

Not so, Paul. My SF1 (#13768) came std with Lucas switchgear and a Tomaselli twin pull throttle (two separate cables from throttle to carb). i've still got it.

 

[JoePurple73]

My SF1 (#12633) also came with the twin cables. Bought a new set from Wolfgang a few years ago.

 

[helicopterjim]

My SF0 came with single pull in case no one cares.

[Paul Marx]

A quick look around of bikes out being ridden would seem to indicate that the 1973 model, known as SF1 did come with a twin pull throttle.

my 73 sf1 also had the tomaselli twin pull
