'78 GL1000 Carburetor Air Leak

#1

Post by Stealth126 »

I just leak tested my rebuilt carburetor the way Randakk does in his video. Fuel and air systems hold great. Are there other places that may develop leaks that are not covered in the video? When I put the carbs on the bike it runs okay, but it idles at about 1400 rpms and can't be adjusted any lower. Is there anything else to check or do I have to look elsewhere? One other thing to mention is that the left side head gasket needs to be replaced. I'm working on that now, but I'm just wondering if there's anything else to check before I put the carbs back on. Thanks in advance.

I would check the throttle cable to be sure there is free play and not hanging up.

You might also check the clamps on the intake runners, as well as the sync adjustment screws...

The throttle cables were off the bike for replacement, so we can rule that one out. The clamps were tightened when I put it on the bike, but I did notice they weren't tight any more when I took them off. Must be when they heated up from running they softened up a bit. Turned the screwdriver 3 times on each one before I would have considered them tight. Could that have been my problem?

Yes. Most of us check them a few times after their hot. They will tighten up a little more each time they warm up.

Synchronization could help bring your idle down.

Just posted on your other thread on head gasket. Doing just one side, it’s important to write down which way you turn the crank to move pistons off TDC so you can do the opposite to bring the timing back to where it should be. It will keep the opposite valves in the correct location.
Whatever I suggest here should be given ample time for a moderator to delicately correct. I apologize in advance.
