i have ttr 125 and there is a ticking noise that comes from the engine. I have adjusted the valves but it still ticks. It doesn't tick all the time usually just in high 5th. anyone know what it is?

excessive piston to cylinder clearance? worn bottom end causing the piston to tap against the head?

On my old xr, I had the same problem. I couldnt narrow it down, but I figured it was either my cam chain slapping the tensioner or whatever guides it, or the valves. I could never figure it out and maybe I was way off but thats all I could think. I also remember that when doing about 60 on it it died away...

i also just remembered that it started ticking on the same day that i changed the oil. Do you think that could have done anything?

Spark plug

have you changed the spark plug recently? if you have, check and make sure you have the right one cuz ur piston could be smashing into the plug
