750 dual throttle cable conversion

I want to ditch the 1 into 2 carb cable splitter and install a dual cable throttle, but need to retain a starter button and kill switch, so what have others done?
Thanks

On 750's the earlier version has two long throttle cables connected on the twist grip and the cables are out of balance shortly after adjustment.
The latter system has the splitter with three cables and keeps the cables clearly better in balance.

Splitter hangs up? Secure and/or reroute? Cables has wrong length if the location of the splitter is wrong?
 
thanks, but I find that the cables can easily pull out from the splitter and cause carb issues. many vintage Ducatis use dual throttle cables without any issues.unfortunately the routing for the splitter gets tangled by the other misc wires. I,ve tried securing the splitter w zip ties but it doesn’t help, so I,ll try the dual cables.

my main question was what to use in place of the OEM pod for the starter button/ kill switch which was kindly answered previously.

I agree with Piet and MotoJ, Teddy. The factory replaced the twin cable system for a reason. If yours hangs up, then there is something amiss with it. 50 years of ownership and lost count of the number of hundreds of thousands of km ridden ... with zero problems. I think you'll find very few SF2/3 owners who've ever experienced the issues you mention.

I've got an original SF1 Tomaselli twin throttle I'll happily sell you - If you insist on going this route. One alternative is to grind out your ND throttle to cover the clamp section of a non-starter-button throttle. Personally I prefer as little bolted to my bars as possible.
 
There is little room under the tank on my American Eagle and at times I have knocked the cables when replacing tank and caused the ferrules to hang up on the edge of the splitter and even at the carbs. Usually very obvious, tank back off, seat everything correctly and replace tank with care. If all seated well shouldn't hang up unless there are other issues as noted by MotoJourni.
I did have an issue one time where the cable was slightly hanging at the carb top and caused some dodgy running at revs but not enough to be obvious. I went through everything trying to find the problem before pin pointing it to a hanging cable held out by the rubber boot - drove me mad but at least the bike got a good tune up while eliminating everything else, including replacing points, condensors etc etc:LOL:
(Sorry Teddy, didn't answer your question but as you have a satisfactory answer and as this is a forum for info thought I'd chuck my two bob in;))
 
I consider the splitter to be the superior option and will be changing from 2 long cables to a splitter when (if?) my SF gets out of its slumber-hole this summer.
 
Funniest mod what I have heard (I have no personal experiences about this) is to install rapid adjustment screws for the dual cable setup.
It was stated that the cables can be balanced in a couple of seconds when waiting at the traffic lights.

In cable adjusters as on British bikes are very practical, be it for carb balancing or clutch free play.

That it a different setup. Triples have connection shaft between the carbs and the dual cable means a push-pull setup controlling the shaft. The another cable pulls when throttle is turned off.
On 750's there is no connection shaft and each carburettor has their own cable. Dual cable setup still has spring return only.
 
Both my 1968 and 1969 750's have the splitter. They never had two cables at the throttle? That was how I bought them and they had been sitting since the early 1970's. Other very early 750's I have seen, also have the splitter.

Here is an early one (not my bike).

Only SFCs had dual cables.
One wouldn't want to fiddle with three cables in an endurance race when two are enough.
