Hello,
my 2011 ninja 250 had a clicky noise in the engine,
comparing with some videos i guessed the problem was a loose cam chain.
So i started taking out the cam chain tensioner to check it, then i took out the middle bolt (with a bit of force) and the thread was broken. (as in the picture)
I don't know if i broke it when i took out the bolt or if it was already damaged.
I wonder if this could be the reason why the cam chain is loose?
Other than that the CCT seems to work properly so i don't think it is le cause of my problem.
What do you think ?
