So polishing up the slides that were on the '76 carbs didn't work out so well. I still have surging RPM's off-idle. Frustrated, I said fuck it and scrapped them altogether.
But I do have an ace up my sleeve.
|I just pulled these beauties off a (for parts) set of 755A carbs.|
The best part about these is they're a complete set of matching tops and slides with no damage or scrapes.
They were a bit dirty though.
...and after 5 hours of polishing: (my forearms look like Popeye's)
|The needles buffed out nicely.|
I really hope these do the trick. I've been on a wild goose chase for about a week now hunting down one problem after another with this bike. This past weekend alone I've had the carbs on and off the bike 5 times.
The bike starts and idles fine, but still seems a bit slow to decrease RPM's.
I'm going to set the timing dynamicallty, then try and sync the carbs as best I can and see if that makes a difference.
I already swapped the #115 slow air jets for #110's. It was quirky at first but eventually I got the idle adjusted and now it idles strong.
