The first one is correct (3719), without the second one.

Just to clarify, the first one is correct.

The second one you would only use if :-

a). You wanted an extra return spring to the one already built into each of the carbs, or

b). If you wanted to do away with the internal return spring in each carb.
(I wouldn't advise it, but some people do). There have been a few very minor instances where an internal return spring has broken and prevented the throttle spindle from closing, but we are talking 000's to 1 chance.

And you will need the big return spring which connects to this.

James will only need the big throttle return spring above, if he's using the original airbox,as t'other end of the spring locates in the bracket that's part of the airbox rear pan.

|Try this for size. More info on request. Works brilliantly, smooth, short cable run, Colin would have approved!
