So I bought a '78 KZ400. I've been tinkering with it trying to get it to run right. I had the carbs professionally cleaned, got new sparkplugs and sparkplug wires, and a lot of other little parts.
The biggest problem was that just one cylinder was firing somethimes and it would alternate sides. But today, I got it to run on both after messing with the air/fuel ratio.
So while it was running, all of the sudden "CLUNK" bike makes a bad noise and just shuts off. Tried to crank it over (I only have kickstart) and the kickstarter was frozen and wouldn't turn over. My friend and I tried a few things, thought about it and decided to just taking apart the engine. Didn't find anything, but when we decided to turn the engine over with a wrench, it turned over! So what is wrong?! The kickstarter bearings? Does that make any sense? Before you ask, yes there was plenty of oil in it.
Any help/guidance would be appreciated!
Here's a sparknote version for those who don't want to read my story;
-Bike running on one cylinder radomly.
-New plugs/wires.
-Kinda fixed.
-Ran on both cylinders.
-Clunk. Bad noise.
-Kickstarter stuck, won't turn the engine over.
-Engine will turn over via the bolt with a wrench.
-Top end of engine is now dismantled.
-HUH?! Help?!
Here's a pic just cause I know there will be at least one of you asking for one
