Sticky slides cured!

Post by Gun » Wed Feb 18, 2009 1:59 pm

but if you think that solved my problems you've well under-estimated my ability to not fix a motorcycle.

once i got the additional slide springs out of the way, a bit of slide polising was in order to cure the original problem that the previous owner tried to resolve with the additional springs. For this, I went to an old timer that lives on the edge of town. I helped him with some computer problems a while back, and he restores old kawasakis... and that's as close as i could get to a feller in Bend that could work on this bike.
we replaced the throttle cable, and the slides pop back pretty smoothly. we adjusted the slide and air screws, put that choke at 3/4ths closed, first kick she started up but BOY was she idling high!
and nothing i could do could change that.
is it possible that in over the last 6 months of not riding this bike the timing got so far advanced?
would having my slides in the wrong carbs do this?

This may be obvious but it's what happened to me: have you adjusted the length of the throttle cable down at the adjuster?

Gun, this is what I did on my CB77's carbs when they were sticking— In my particular instance, the carb flange/head-port insulator surfaces were warped. After stripping the carbs, I lapped the flanges on both carbs with sandpaper on a thick, flat sheet of steel. Once the flanges were flat and true, cleaned and re-assembled, they stopped sticking.

Get a soft, new set of O-rings and don't over-torque the carb-flange nuts. Try it…

Adjusted the throttle cable at the tops of the carbs, and she started up right at about 1000 rpms.

however, still slow to come down off of the throttle. Also, the exhaust seems white, mostly out of the left.

Slides don't appear to be sticking.

I'm working with the needles and jets from keyster kit, still have original brass on hand.

any ideas on how to sharpen up this throttle response?

The slides are not at equal heights. ................lm

I'll get to figuring out how to adjust the slide heights properly.
