"Damn my wrist hurts" or How tight should my throttle be?

[Kev Nemo]

The title says it all. Being an old bike, I'm not quite sure how tight the damn thing should be (if it was light and snappy like my CBR, I would be sooo damn happy) :-\

how do you have the throttle cables ran around the frame. Sometimes if they are ran "funky" (yeah, thats a technical term) it can cause snap ups, and stick a little. Also, if you rebuilt your carbs,( in know this sounds dumb...please don't take offense) did you put the right throttle cable in the right spot? just a thought....if I can't help...just ignore me! ;D
Good luck

I changed the return spring on my cb750 for a softer(i had the same problem).

Ditto on the cable routing. Even small changes make a large difference in how smooth the cables work, especially if they are old. Previous owner may also have put a stronger spring on to compensate. Get some new cables, they're pretty cheap. Route them carefully with nice big bends and you may be able to put on a much lighter spring.

Hmmm-think the cable might be dirty?

I cleaned the throttle assembly with some Chemtool and blew a bunch of grime out. Returns much better but the new issue is much weirder. So I get up to speed (street/highway) and when I come to a stop, the motor is revving up to 3k, even though it was set to 1500 when I took off ???
I usually back the idle screw out to get it back to 1500, but it usually does this a few times until the screw is backed almost all the way out.

so what's the verdict?

Check that your throttle cable is allowing the throttle to return to it's stop-check it from end to end. Make sure you don't have an air leak at the carb joints. If you have points, make sure the mechanical advance unit is not sticking.

The leak is definate maybe :-\
