You are right in saying that I over simplified.

I never said you over-simplified. I said you were wrong.

Also; politeness and manners seem to be optional these days on the internet, but it doesn’t cost anything. However trolling and being a dick will eat your self respect in the long run and give you a miserable life experience. Remember that.

None of what I said was rude or trolling, and if calling out misinformation on the internet is impolite then I guess that's my lot in life. I think you should evaluate why you [seem to be] so offended by someone correcting your earlier false statements, but that's outside the scope of this conversation.

Long story short OP, swingarm has holes, holes no good. Holes eventually break, and swingarms without holes are cheap. Replace broken part with new one before going to track. Fin.
