Vintage twin pull throttle

Any one ever seen one of these and know who might have made it? Made in Germany

Maybe older magura?

Not anything I've seen....
I use the Domino (made in Italy) dual pull when needed for race or premix twins.

I pulled this off my Daytona about 5 years ago. A PO had it with the stock 2V0 carb setup.

its a magura 'trap door', had one on the lightweight, i still have it. they still sell them i think, i liked it a lot. used on british twins frequently. good quality.

you can actually see it here

Thanks Mark.

I thought someone here might have seen one before. I was debating whether to keep it or not.

I wonder if carb sync would be less exact when using 2 cables and a dual pull throttle grip, vs a single pull/ cable and a splitter under the tank.
Running pre-mix on my 350 for the time being, and sort of worrying about non-symmetrical pull on the stock 3-way splitter, after I removed the oil pump cable.

nope. super easy and IMHO more precise.

i changed to an r5 one because the cable length was too long on the project, but i have a dual pull domino on the lc hybrid and its awesome. pricey, but totally worth it

Magura Type 305 (for two cables - stroke 44mm)
not sure, but i mean it is from an older BMW-Boxer bike

Why would it be asymmetrical?

the early splitter -can- cock the disc a bit, but really not enough to matter. usually its from people have the cables twisted in the housing or a kinked cable though.

Been looking fora dual pull for a bit. Never knew about this one. Let me know if want to part with it!

Russes is on ebay, and cheaper than a single pull trapdoor (new like 89 bucks). id snag it.

if this isnt Russes its a hell of a coincidence.

Yep it's on Ebay with a low starting price and I purposely under-priced everyone else. And granted, it's old and well used.
I couldn't find any other twin pulls.

Because the cable to the throttle grip is attached to the center of the white plastic slider, while the cables to the carbs and oil pump are attached on the periphery, 120 degrees apart. Removing the oil pump cable will cause the slider to become somewhat cocked inside the splitter housing. Possibly causing more friction and maybe a stuck throttle.
