Faint whining from the engine

[Alex Knickerbocker]

Hey guys , a faint whining just started coming from my engine, seems to be at the back end of the engine, it gets louder with revs . Does anyone kno what it is and should I be worried?

That's the flux capacitor winding up. You should only be worried if you don't have legal tender from the 1950's. Just kidding

What does the whining sound like (hard to answer, I know)? Does it sound like the fuel pump when it primes or more like a squeaky bearing? Also, does this happen at idle, riding speed, both, etc?

Primary chain is probably too tight.
