This is the post that got me to thinking it would be easier, as in not having to re-do all the adjustments, by being able to set the carbs up on the engine to work on. I don't think this can be done on an RX with the pipe on. This post was about a 951 engine on an XP:
There are a few tricks that save a ton of time when removing and replacing carbureators. It takes us about 10 minutes to either remove or replace the carbs on a 947 engine.
Pay attention.
After you remove the airbox ( which requires moving the oil tank and the oil tank base plate to make room to pull the big plastic air box), remove the allen screw from the bracket that supports the carbs. It goes through the latch bracket and into the exhaust headpipe. Slide the choke cable bar out of the carb choke levers and bracket.
Remove the 4 allen bolts holding the carbs onto the intake manifolds.
Now with the carbs loose from the engine, you can easily rotate them to get to the fuel and pulse hoses to remove them. You can also use a phillips screwdriver to remove the screws holding the throttle cable bracket (with the cables still attached to it) to the carbs and then remove the throttle and oil cable ends from the throttle drum. Do not mess with the nuts holding the cables tight to the bracket, and you will not need to readjust the throttle and oil cables nor will you mess up the TPS adjustment if you do like I said and not remove the cables from that bracket. This will save you at least 30 to 60 minutes or more when you put it back together.
Once you have the cables and the fuel lines loose from the carbs, you can pull the carbs out of the hull and rebuild and rejet them.
Then all you need to do is reverse this process to install them. Leave the airbox in the shop and install my filter kit. They snap right into the grooves at the top of the carbs. Very simple and clean installation. Double check to see if the oil cable came out of the drum on the oil pump, and that it works correctly when you pull the thottle on the handlebars. It should still be adjusted correctly because you diid not remove the cables from the bracket on the carb, you removed the whole bracket with the cables still attached to the bracket. Your oil, throttle, and tps should all still be adjusted correctly.
