throttle cable problem

just ordered the new nalas, so i thought i may as well fit a new cable too
picked up a Venhill N01-4-107 ,which is the correct one for my 750 but the cable seems wrong,or else im missing a part of the linkage.Rang them up and double checked the number ,its the correct one.The twist grip end has too much inner/slack and wont adjust up,there was a threaded nut pushed into the twist grip cable enter and the old cables adjuster was at its max ,so I assume im missing a part but I dont know what it is!

heres a picture of the cable and the twist grip

just guessing it's a '72 with disc
#17?

but it won't take up all the slack in the photo

Edit - I messed up the link, to the old britts page, can't figure out how to do that one - it's the part LAB refers to below

hi all
I m missing that cable stop part,but even with that, i think the cable has been made too long by Venhill,Ive spoken to them and they can alter the lenght whilst I wait,so thats no problem , its just a bit of a pain to get over there

With the carbs connected there is a 40mm lenght of loose inner cable going to the twist control

They double checked ive got the right part number as well

stupid questions time -
all the images show an adjuster on the cable - yours does have one, doesn't it?
adjusters on carb top - fully adjusted?
just for the heck of asking, cable is connected to the carb slides, not the 'choke slides'?
last one - slides are all the way down in carb bodies?
have you compared your old cable to the new one - length of 'sheathing' and length of cable propper? are they different?

yes it has a mid point adjuster,even with this wound right out its too long
same with the carb adjusters , i just double checked the cable is in the right carb hole
compared to the old cable the inner part left sticking out is long,even though the old cable is overall longer,due to the higher bars i took off,even without that the inner part is at least 2 cm longer than the old one,the old one was fitted with the adjusters right out too-probably because iam missing the throttle stop bit mentioned at the top of this thread
I will be going back with the carb and throttle to get it checked at the venhill factory

If it comes to it you can shorten the cable, had to do this myself recently and found some good info at http://www.accessnorton.com/cleaning-cables-soldering-nipples-t13394.html
I used a 1/2" pipe cap for a solder pot and a propane torch for heat, worked great, and it was good to learn how to do it right...did it the wrong way in the past and the cable quickly failed.

These suckers are called FERRULES , theyre great fun to drop on a floor of wood shaveings or grass roadside verges . Recovery tecnique is to close eyes , walk along going O.M.G. ,
STOP and look down straight in front off youre feet . Same as the Timing Cover Oil Pressure Gland / seal .



In fact theres pages of nasty little devices HERE . http://images.google.com/search?q=throt ... art=0&sa=N

Now , all discerning motorcyclists of AngloSaxon leanings , particularrly those opperateing twin cable arangements , are useually utilliseing THESE .



Particularly Assembled ones. The two bits thread together , giving a in line mid cable fine setting facility . Usually adjacent a frame tube ( backbone in this case )
on a Straight Run ,
Taped past ends to frame tube
for friction free consistant opperation .

Apparently these suckers have all sorts of things .

Someting like this ,


But like a 50s Triumph , without all the screwthreads . Can be usefull on some bars .To stop the cables catching in branches and small children , wolves and forign matter .
Or for low frition carb entry under a big flat wide tank , like on a Featherbed Frame .
