Start and ride bike without key + Very hard to start
I hope it's not taboo to ask about another bike here...
My buddy bought a 1972 Honda CB450K from a used motorcycle vintage dealer. They were supposed to have fixed up the bike as it was a "Barn Find", but they definitely lied about it. He's had issues from day 1, and they obviously refuse to do any of the repairs for free, even though he literally brought the bike back the next day for issues.
With that said, he's replaced his stator and battery through them.
Now, the bike is very hard to start up, and he can also start it and ride it without a key. He has to disconnect his battery when he's not riding it to make sure it doesn't drain it all night.
I've been looking online, and I think we should try to clean his carburetor, but I've had such success on this forum with my bike, I wanted to ask for yall's input.
Also, any ideas of how to fix the whole being able to start it and ride it with no key (even though it's in the off position)?
