My 77 has a issue, When I first start it up I get some popping and a little backfiring until it warms up.
I sprayed brake cleaner around the intake tubes and that did not make it rev up so I dont believe there are any leaks. Once it is warm it smooths out and runs great. Any ideas? I am thinking maybe coils and or wires?

Have you checked the valve lash?

Re: 77 GL1000 popping
Is the popping in the exhaust or intake?

Popping is either water in the mufflers or exhaust leak.

Just until it warms up? They run pretty rough on the choke, so just give it time to warm and don't worry. We have been spoiled by EFI.
