Adjust idle

Hi Rick:
There is usually an Idle adjust or throttle stop adjust on the throttle linkage at the Carb. If fuel injection, check the throttle control linkage for an adjust screw.

How do I remove throttle cable on 2002 dyna super glide

Loosen the cable adjuster jam nuts, screw the throttle cable adjuster until it is as short as possible, remove the two screws that hold the handlebar housing together to separate the upper and lower housings, unhook the ferrules and cables from the throttle grip and lower housing, remove the air cleaner assembly and disconnect the throttle cables from the carburetor, pull the cable from the housing by placing a drop of oil on the retaining ring that holds the cable in the housing, then firmly pull the bent tubing portion of the cable out of the housing using a rocking motion. The cables can be removed from the carburetor by pulling the outer housing away from plate above the throttle wheel and then with slack in the inner cable twisting the inner cable to allow the swaged end to release from the slot in the throttle wheel and then pull the inner cable out through the mounting plate hole.

If you will reuse the cable wash all components in non-flammable cleaning solvent, carefully blow all parts dry with low pressure compressed air, replace the control cables if frayed, kinked or bent, put one or two drops of oil into the housing of each control cable.

Apply a light coating of graphite to the handlebar and to the inside surface of the housings, attach the control cable assemblies to the lower housing, push the silver insert of the throttle cable housing into the hole in front of the tension adjuster screw, push the gold insert of the idle cable housing into the hole at the rear of the tension adjuster screw, install the adjusting screw, spring and friction pad in the lower housing if they were removed, position the throttle grip on the handlebar, place the lower housing on/over the throttle grip, position the ferrules and retaining rings over the cable balls and seat them in the throttle notches, fasten the upper housing to the lower housing using two screws tightened to 35-45 in-lbs (4.0-5.1 Nm), CHECK the throttle cable routing, on FXD, FXDL and FXDX models, the throttle cables are routed between the headlamp bracket and the front fork upper bracket and then under right side of tank to carburetor. On FXDXT models the throttle cables are routed through a wire form that is mounted on the upper fork bracket. On FXDWG models, the throttle cables are routed behind the front fork upper bracket, then under the right side of the fuel tank to the carburetor, install the throttle cables on the carburetor and adjust them at the handlebars and re-install the air cleaner. The throttle cables must be clear of steering stops and not be so tight that the idle speed will be changed when turned from steering stop to steering stop.

Throttle Cable Adjustment
To adjust the throttle cables turn the cable adjusters and jamnuts as short as they will go so that both cables will have zero adjustment at the start of the adjustment procedure. THEN with the front wheel pointing straight ahead turn the throttle grip wide open and hold it there, turn the throttle cable adjuster to lengthen the sleeve until the throttle cam just touches the cam stop. THEN tighten the adjuster jamnut and release the throttle. THEN turn the front wheel full right and turn the idle cable adjuster to lengthen the sleeve until the cable housing just touches the spring in the cable support sleeve. THEN recheck the adjustment by working the throttle grip to be sure the cable returns to idle position when released. If the cable does not return to idle, turn idle adjuster to shorten the sleeve until the correct adjustment is reached and then tighten the jamnut. The throttle control must operate freely without binding.

Replace throttle cable

There are two cables leading to the throttle. Both have two pieces.
Cable 1 goes from the throttle about 12" long and connects to an adjustment piece joining it to cable2 which goes to the throttle body.
Cable 3 also goes from the throttle and is about 12" long and connects to and adjustment piece joining it to cable 4 which goes to the spring on the throttle body.
To change any of them you must loosen the adjustment piece until the ends can be removed from it.
Then to change cables 1 and 3 you have to remove the throttle cover on the grip. you will be able to see how they are removed. Then reverse these steps to install the new cable.
To change cables 2 and 4 in no more difficult but more time consuming as you will have to route these longer cables from the adjuster to where they connect to the throttle body.
When cables have been install and all parts reassembled you can carefully adjust the tension on the cables until the throttle responds the way you like it.
Hope this helps

I changed my grips and in doing so my throttle cables have moved. the idle is loose though the throttle is not bad. was wondering how to adjust cables.

There should be an adjuster in each cable just below the throttle assembly. Push the adjuster cover up to get to the adjusters. Loosen each adjuster lock nut. Adjust the throttle cable first. Adjust it until it has just a bit of freeplay in the cable. As you attempt to twist the throttle, you should feel a little freeplay before you feel the throttle start to open. Then adjust the idle cable the same way. When finished, lock the lock nuts so the adjustment doesn't change. Now, twist the throttle wide open and release it. The throttle should snap closed. If it doesn't, you may have to loosen the two bolts that hold the two switch housings together and slide the assembly down towards the end of the handlebar about a quarter of an inch. Try the throttle assembly again at half throttle. It should snap shut. If not, continue until you find out why. If the throttle does not work correctly, loss of control of the machine could result and the rider could be injured or killed. Make sure the throttle works properly.

If you move the throttle switch housing down on the handlebar, check the rear brake light. If it is on continously, you must move the front brake master cylinder down against the switch housing. Loosen the bolts and slide it down towards the switch housing as far as it will go.

Good Luck

How do you adjust the throttle & idle cables on a 2009 sportser

Each cable has an adjuster near the throttle grip. They may be covered by a rubber boot. Slide the boot up so you have access to the adjusters. Loosen the lock nut on each cable. Now, adjust the throttle cable first. You want a little freeplay in the throttle grip when you start to turn it. Once you get it adjusted to that point, lock the lock nut. Then adjust the idle cable until it stops and back off just a bit. Lock the lock nut.

Now, with the engine OFF, twist the throttle to the wide open position and let go of it. It should 'snap" back to the closed position. If not, you may have the throttle cables adjusted too tightly. Back both of them off just a bit and retry. You want the throttle to "snap" shut on your bike. If not, it could cause you serious injury or death. If you're not certain of what you're doing, find someone that is experienced at doing this. You don't want your throttle sticking on your bike. This could be dangerous.

Good Luck

I have some play in my throttle control how do I ajust it or should I take it in.

You want some play in your throttle control. If you adjust the cables until you have no play, your throttle will quit automatically returning to the closed position. Not a safe thing since most people today are accustomed to the throttle doing that.

Now, you don't want too much play either. less than a 1/8 of a turn. Take the play out by adjusting the throttle cable first and the by adjusting the idle cable. The throttle cable is the front most cable where it enters the throttle twist grip.

Important, once you adjust the throttle cable, you must insure that it operates correctly. Twist the throttle to the wide open position, with the engine OFF of course, and release it. It must automatically return to the fully closed position. Failure to insure the proper operation of the throttle can lead to serious injury or death.

Good Luck

I know its a stupid qeustion but where exactly on the motorcycle is the air screw and throttle screw. I have a 2007 Suzuki rm125.

The air mixture needle valve is on the Carb. Throttle screw as you call it, you might be referring to 1- throttle adjustment at the twist throttle hand grip. 2- At the top of the carb is a throttle cable adjustment 3- some times somewhere between the twist grip and the carb there is an adjustment.4- there is also a idle adjustment at the carb.3a37cbb.png

Idle seems too low. runs great, when no throttle, stalls. maybe idle too low. no manual, need to know where idle adjustment screw is

If you haven't already adjusted the carb there are usually 3 adjustments. H - adusts performance at full throttle (how it cuts in the wood). L - adjusts performance at idle and accelleration to full throttle.It sounds as though those are fine. The third adjustment T - is the throttle or idle speed (often away from the other 2). If my saw that is the one adjustment I'd make. You supplied no make or model, it is difficult to provide what you requested without them. HTH

Need to adjust throttle but there is not an adjustment on throttle body

That is correct. throttle adjustments are controlled by the computer. Any other adjustments will need to be done with a graphing display scan tool.
