Electrical / Carb / Idle KZ1100 HELP!

07-25-2018, 03:27 PM
Hi everyone,

Getting ready to drive a 1982 Kz1100A from SF to Boston and keep having a reoccurring problem:

Headlight goes out. Blinkers stop working temporarily and at the same time the engine is doing some strange things. I am fairly new to motorcycles and have done some "work" on the bike myself, but it's mostly trial and error.

I just cleaned the carburetors with help from a mechanic and was hoping that would make the bike run smoother - but it sounds the same:

When it idles, sometimes its very high (almost 3k) and sometimes it sounds like it's a bout to die.

When I drive on the highway, sometimes the RPM will just drop to 0. Zero! and then randomly, it will go back up and the bike will lurch forward.

Any help would be greatly appreciated!! Thank you!!

Start by checking the battery ground where it bolts to the engine case. Clean it no matter what it looks like. There may be another black wire on that bolt that needs cleaned. Simple stuff 1st. Bad grounds can affect many systems.
