Throttle tube question

[whiterabbitt]

I've searched the web for about 3 hours today and still have no answer to the question,

What replacement throttle tube will fit in my 77 GS 750 metal r.h. control?

I have tt's from several Suzuki's but none of them fit in the metal housing. I could get an OEM one but spending $30+ for it isn't appealing since I need 2 and I would be peeling the grip off anyway.

Any held would be appreciated

You have the twin cable pull-open-/pull-shut setup still?
Here's the x-ref for what else was fitted with that throttle tube.

If it were a single-pull, as for the CV carbs, I've found the GS500 throttle sleeve fits perfectly.

Thank you for the link.
Yeah its push pull. With the thin cam I am having a hard time finding a more available, less expensive option. I don't care what it comes from, or what the profile is, as long as it fits the housing, I found a Yamaha MX one that almost fits and a BMW/KTM one that is thin enough but the tube is too big where it goes through the housing.

My question is in regards to a drop in part, cam profile disregarded, that is readily available and inexpensive.
Because im'a cheap basterd.
I could shave down any number of t.t.'s but, basically, for my and everyone else's benefit, I was asking about a drop in aftermarket or current market part that is readily available and inexpensive for the gs750b, gt500, gt380, gs550 etc. With the metal switch housings.

It's a feel thing, I feel like the plastic (glass reinforced?) Switch blocks are cheap. Even on my Gsxr.

I like the metal switch blocks on my 77 gs750B's that were made in July and August of 1976

You could go with a single cable and a return spring at the carbs. I did that for a long time with no trouble. The only reason for the pull-shut second cable is in case of stuck carb slides, but you always have a killswitch there.
