Noise on a Honda CBF 125

[Guest]

Hi guys i have a Honda CBF 125 bought second hand started riding it on the 23rd of December and almost every time i start up after around a minute there is one metallic clicking noise. Now mechanic wise I don't know much, the only thing I can think of is that the bike is F.I and has an automatic choke and I'm wondering if it is just that disengaging? anyone have the same noise or knows what it is?

Many thanks

Is it a regular click?

Could just be something in the head clicking as it hasnt recieved much oil yet (speaking of which check your oil levels)

Whats the mileage on it? As perhaps a valve clearance is out. Or its a cam chain tensioner that works properly when the oil pressure builds up a bit. My 600 has that, i hear a faint click at idle but it goes away when I rev up and its warm

Could be quite a few things really, but to sum up, if it is consistent, doesnt get worse or change then I think you're all right

Could just be something expanding as the engine starts to warm up? Exhaust?

I have drag pipes on mine , so can't hear much when it's running. However after a spirited ride on a summers day the thing is clicking and pinging for about an hour as the hot parts shrink and cool at different rates. Clicks and pings when warming and cooling are normal. Rattles, bangs, knocking and screeching indicate a problem
