Carb switch on a GS425

[Guest]

Hiya folks,

I got some carbs from a parts lot that were reportedly on an '81 GS450. The spacing is the same on my bike. They have they idle adjustment knob toward the bottom and are a pull only cable setup. My current carbs are push/pull. Would it work or even be advisable to switch them out and just eliminate the push cable on my throttle tube? I'd like to switch them out because the "new" carbs seem in better shape and the idle adjuster seems much easier to work with. Thanks

If they line up etc. then they should be fine.

The push/pull vs. just pull won't matter as that relates directly to the throttle linkage setup on the carbs themselves.

The only thing I can think is that you'll want to verify the jetting although only 25cc's difference shouldn't make too much of a drastic difference I would think... possibly just a little on the rich side?

Thanks Pete, I'm going to give it a try. Had some more issues with fuel delivery today (I think) so I'm willing to try anything. :/

What's the problem you're experiencing? And definitely let us know how the swap goes.

Well Pete, I can't get the idle set properly and have to give it a lil bit of throttle just to sit at a light, and then yesterday it is "surging" for lack of a better term, no power from a stop and then a bunch, then "bucking" and then just finally died out on me. Oh, and I got a weird chirp noise at idle seemingly from the left side, gonna check the clutch adjustment.

Doesn't sound like much fun! Made sure your airbox is all sealed up and filter has been cleaned and oiled properly?

It almost sounds like a more serious version of what mine gets like in traffic... mine's rich, bogs off idle at small throttle openings, and holding at 1/8 - 1/4 throttle at the speed limit tends to produce some surging...

Well crap, that didnt work. Spacimg was WAY off... Gotta get the peepers checked and keep searching for the problem...

You can't swap brackets or even make up a new bracket to suit?
