TPS on slide carb?

[Voltaire]

Anyone done this? carb is question is a Dellorto 36mm on a BMW with an ignitech ign.

I've never seen a linear TPS, but something could be made to work. TPS are normally rotary, put one on the end of your throttle tube.

not done it myself but have seen a guzzi that it had been done on. there was a pin tapped into the carb slide that ran parallel with the throttle cable exiting out through the top of carb, the pin was positioned just to one side of the throttle cable entry point. This ran up to an arm that ran off to a pivot point secured to the front of the carb. the TPS was secured to the other end of this pivoting pin. the angles of the arm etc will take a bit of working out to get the movement in the pin you will need. you also need to seal where the pin exits the carb cap or the air leak will cause the fuel mixture to go lean at low revs.

It can certainly be done.

A friend in the UK was running TPS on a Ford X-flow (1760cc) engine fitted with Weber sidedrafts.

Sorry - I don't know the details. Worth exploring, though.

The Keihins on the KX125 are slide TPS std.......think some of the others had them too.......plus the FCR on on the foul strokes.
But the Rgv250 has a TPS built into the throttle cable.........

but you can do your own too.

They have a butterfly spindle which would make it easy, I'm looking at a slide carb .

cheers, that last pic looks like the sort of thing.

Motu's idea of fitting it on the throttle would work, might look a bit untidy...

I couldn't find a decent pic but the RGV and Aprilia 250 have the setup std (in pics 3 and 4) its like the last pic (5) only productionised the ones i posted are bad angles, its just basically a split-er. the NSR250 have a tps as well but they are roller slides.So set up like car

this should be a better pic

One of these (or similar)and mount the TPS off it (don't ask me how)

You could try a two stroke twin with oil pump cable, use the oil pump cable to work the TPS

Some fly by wire cars use a remote TPS - some Mitsi GDI, electronic pump diesels have one on the accel pedal. I like the 2 stroke idea, get an old pump and mount it on that.
