Throttle Cable Sticking - Asking for picture...

Hey,

I just finished rebuilding and installing my engine but am having trouble with routing the throttle cables. I thought I put them back to original location but my throttle is sticking. I let the cables go 'straight' and no problem, route them through that cable hook on the frame and the bends cause it to stick.

Does anyone have a picture or two of their cable routing? I'm sure I'm doing it right but just want to confirm that maybe I've got an extra kink I don't need. If you have pictures all the way from the carb to the throttle grip that would be great and very helpful! Thanks!

just a thought....did you oil the cables?

what happens if you adjust the throttle cable AFTER you routed them?

I'm working on putting some lubrication down them as we speak. the manual said to put in the lube from bottom side but I'm attempting from the top. As for adjusting, you meaning to adjust the bottom adjust screws and see if that helps? I didn't do that yet but can definitely try. For some reason I still think that I'm screwing up the routing a bit... I'll post pictures and maybe get some advice on that at least..

I reassembled the cables after lubing them up (seemed to function when I pulled on them by hand), and it seemed to work when the steering was left.

But when I turned right the cables really were sticking and even in neutral position still a bit sticky... Here are some pics of my routing of the cables.

Let me know where I'm going wrong...

I even backed off the adjustment and didn't seem to help any.

One thing I noticed is that on my bike the throttle cables are just to the right of the radiator fill cap. When the fill cap is on, the cables sit right behind the right hand tab of the cap. Not sure if that would fix your issue though...

The adjustment is on the throttle housing on the handlebars....when I took mine apart to oil the cables (from the top), I realized rather quickly that if the adjustments on the throttle grip is too tight, it will cause binding.

you need to leave a little play in the cables or the throttle grip will bind.

1) Loosen the locknuts, and unscrew both throttle cable adjuster nuts IN fully at the upper end of the cables to give the throttle grip plenty of play.

2) with the throttle grip completely closed, turn out the deceleration cable (outer cable closest to end of the handlebar) adjuster nut until the inner cable just becomes tight.
tighten the locknut.

3) Turn the accelerator cable (inner cable closest to the center of the handlebars) adjuster nut until the correct throttle grip free play is obtained.
tighten the locknut

Check that the throttle linkage lever stops against the idle adjusting screw ( carb end of cable) with the throttle grip closed.

looking at the photos....they look correct to me, but the only thing that could be wrong is where the cables snake behind the top bolt on the air filter pods (ears).

I don't recall if mine are to the rear of the bolt or the front like you have yours. I know the top end and the section right next to the spark plug looks exactly like mine.
