Carb question. '83 RT

OK, Here come the questions.

First thing is that after the bike is warmed up it idles way to fast..
And while it certainly runs it seems like it may be a little on the rough and shaky side.

Luckily the riders manual was still with it and it gives the basic carb setup procedure... I'm going to try that first..

It has way too much freeplay in the throttle cables as well. You can pull them out about 3/8" with the throttle fully closed. And one is quite a bit worse than the other so I have no doubt that the carbs are opening one after the other and this can't be good..

It seems to idle just fine at first when it is cold. But after you warm it up it's way too much.

Anyone got any input for me on this subject ? I could use a the basics on getting the carbs right.

I also have the Haynes book for this bike. But it covers too many models and sometimes I think it's a crapshoot whether or not I'm reading the right instructions for this bike.

Any help with the carb issue will be greatly appreciated. Bing carbs.

On that era R bike the first thing that needs to be done is to adjust the valve clearances. These bikes are known to have soft valve seats and the clearances nedd to be checked frequently especially after the 50K mark. Then check the diaphrams in the carbs to see if they have holes in them before attempting any adjustments.

make sure you adjust choke and throttle cables w/ about 1/16" freeplay.
sounds like you also need to snyc the balance between the 2 carbs.
