crf 50 making weird noise??

Recommended Posts

when i ride it i hear a loud ticking sound coming from the engine. i changed the oil and put the right amount back in. anyone have an idea on what it might be so i can order the right part?

thanks.

does the speed of ticking match the speed of the engine? Have you adjusted the valves latley? If not you may have a loose valve.

ya the noise is acually a knocking noise. but it does match the rpms but only in the lower-end power.

and it was doing this before i changed the oil, thats why i tried to put heavier oil in but it didnt do anything.

So this happens on hard accelleration only ?? ... Not at idle ?

Could be soo many things ...

1- clutch problems or lock nut is becoming loose ?

2 - cam chain is stretched or has tensioner problems ?

3 - worn out crank or connecting rod bearings ?

4 - Fly wheel nut may be loose ?

--- if nut was loose ..., check the crank shaft , flywheel and flywheel key for damage before run'n it any more .

Great post, only thing I can add would be to check the valves.

Yes excessive valve clearance would indeed make noise all the time and it would actually get slightly louder as the rpm's increased but so does the sound from the exhaust, engine, wind etc. Often when people say they only hear a noise at low rpms it's b/c at higher rpm's the sound is being drowned out by all the other sounds a high reving engine makes and not b/c the sound actually goes away. It may not be the case here, but for all the time it takes, it would be one of the first things I'd check. 👍
