Clicking Piston Sound

[doobyboy26]

Hi again guys, I started my quad the other day and went for a little ride with it. There seems to be a clicking noise coming from the piston... All I hear is, click! click! click! click once the quad is started coming from the piston. I can hardly hear my pipe because of this sound. Anybody know why this is happening ? Thankx !

Valves out of spec? Timing chain worn?

Could be ! I bought this Quad second hand so I really don't know. The other day my cam cover was on upiside down, so i put it back strait. I don't know if this could be the issue.

Should I shoot a video and show you ?

 

[beastlywarrior228]

Yep

 

[doobyboy26]

Yep

Alright Ill go shoot that right now... It's 13:18 PM right now should be on near 14:00 or 14:30. Thankx dude !

Might check valve lash and maybe check cam chain like Beast said. Kinda sounds normal to me.

 

[YAMAHAULER]

sounds like a stretched timing chain and valve lash needs to be set a little tighter

 

[Fprater937]

I'd say definitely the valva lash

 

[88WarriorBoy]

yep sounds like valve lash to me or a possible exhaust leak somewhere

Really sounds like the valves need to be adjusted.

That is valves. Adjust them and they will quiet down some. These bikes are known to have noisey valves. If it was piston slap it would be making more of a knocking noise.

Ditto!!^ If you think that's noisy put a cam in it.

My bud bought his warrior with a 252x1 already in it, with HD springs, and it is super quiet.

 

[doobyboy26]

Ok... So I'll first start by adjusting the valves... Thankx alot guys !
