why

why do i not have any free play in my throttle control? how to fix?

What bike?

Check to ensure slack at the carbs, and at the throttle itself.

Its usually a case of just loosening a nut, then spinning the other until desired play is achieved, then retightening first nut. At both ends...

well i gotta be doing something wrong. i have a 76 kz400. ok well when i hook on the cables to carbs . then i twist throttle the throttle control just seems tight i mean when i give it gas there is no play at all . when i move throttle it rite away gives it gas. there is no slack at all.. and it idles at 3000 rpm. and i have no vac leaks

OK. the slack is adjustable at the handle also.

Do you have FSM? Manual? Should be pretty clear in there.

You should be able to put as much slack as you want to at the handle just by playing with the nuts, almost just like a bicycle.

Just play witht them, you'll get it. Or take it completely apart, then re-assemble. Pretty easy...

Adjust your idle screw out to drop rpms. If that doesnt work, then its the throttle hanging up the rpms.


OR... Disconnect the throttle cable from the carbs completely, and start the bike. If still idles high, then turn out idle screw all the way. If still idles high, may be vacuum leak or slides are not properly adjusted/sticking.

GL!

Maybe these help:

#24 in first pic is idle adjust screw.

If not already done, would also assure smooth cable curves and routing between throttle grip and carbs, especially along frame tube under fuel tank, to prevent kinks and sharp turns from impairing smooth complete cable action.

New throttle cables might be needed.
