>_> i have a 125cc warrior, its done the same thing, means the carb needs cleaned

[akamyers]

dude i just brought one today and it does the same thing but it is run just fine im just gonna change the oil

[mrlonely199]

you bought a pile of crap dude thats whats wrong

[TheLuckeydc7]

No big deal, just your piston knocking a lot of fourwheelers do it.

[spezz01]

might be valves or your timing isnt good, or maybee the piston is getting used.

[stonie231]

thats the cam chain bro

[ddocmayo]

low on oild dipshart

[arbitor55555able]

@ddocmayo your right because my o2 warrior had low oil and it knocked every time you tried to start it

[deerman1212]

just make sure your oil is changed and valves are in check.

Man i cant really tell what it is but try changing the oil.When you do put a thicker oil back in it and see if that makes it quiter.
