Hello,
Just got my a 1983 kz750 Ltd4 a couple months ago, wouldn't start so I cleaned the carbs and she's up and running! Realized after taking it around the block that the throttle hangs open if I don't push it back and there's not enough force on the throttle cable to return back to idle.
Here's a couple questions:
1. Is it supposed to have a return cable?
It only came to me with one cable for the throttle. I didn't notice a spot for a return cable connected to the carbs or anywhere to screw one in.
2. Is it possible the return spring is just weak?
I put some oil down the throttle tube hoping it would help but it didn't seem to really aid my situation. The return spring works, but I have to push the cable back so far before it starts to actually pull it back. I adjusted at both ends but there seems to be some play that I can't get rid of.
I am hoping I don't have to remove the carbs to get to the spring, but I looked and it looks like I might. Any tips?
Thanks,
Jakob
