Knocking sound

My cb500f only have 1200 km on ODO, but i think there is a knocking sound, from the engine, at around 3000 rpm, when its cold -

When its varm its gone

Is this normal

Must say that the "honda quality" has not impressed me so far

Does the bike have any modifications to the engine or exhaust?

Could you have filled up with gas with too low an octane rating? Not a problem in most countries.

When I first got my CB500F I shifted gears to run the engine around 3000 rpm. I found the engine was not happy accelerating from 3000 rpm, though it would do it. Now I ride around 4000 rpm (or higher) and the engine is happy.

Ah, now I understand the comments in all your threads about Honda "quality" (or lack of it).

If I was doubting my bike every time I rode because of a bad experience like you had, it would ruin the enjoyment of motorcycling for me.

Why not trade your Honda for another brand, so you can put your doubts and frustration behind you and start smiling again?

I'm serious.

Honda was the 1st Asian bike sold in the US, and they're still here for a good reason. Thy produce a really well made and dependable motorcycle, at a competitive price. Sorry about your previous experience. But that sort of thing is such a rare occurrence with Honda. Don't let it deter your enjoyment of riding. Good luck with the bike and your studies. Ride Safe.

Since around 1975 the knock on Honda was that they built motorcycles with basically "throw away" engines. Not really intended for long term. I know, I know, that they really can be rebuilt, but the cost vs. the cost of throw-away and get new bike is such that most people will opt for new bike.

That's why they make them cheap!

Unfortunately the others do the same thing - including BMW (my old long term rides) which now are no better than the rest.
