Noise from engine

[88WarriorBoy]

Does a starter cltch keep making a thunk noise even when running ? Because I have a really loud thunky noise comin from my left side of the engine

 

[88WarriorBoy]

bump

 

[Gen1Pat]

Idk. Never had that happen. Time for a vid.

 

[88WarriorBoy]

lol yeah I'm goin to check tomorrow to make sure it is not an exhaust leak tomorrow

 

[88WarriorBoy]

I mean it almost sounds like a knock but if the crank was knocking wouldn't there be alot of engine vibrations too ?

 

[Gen1Pat]

Not necessarily.

 

[Gen1Pat]

Take the stator cover off and have a look in there. Does it stay consistant? Or, does it change with engine speed?

 

[88WarriorBoy]

When I rev it the noise speeds up

 

[Gen1Pat]

Could be several things. Crank bearings, rod bearing, piston slap, piston pin rod hole out of round, something loose inside the stator cover....

 

[88WarriorBoy]

oh great lol the funny thing is it is hardley noticeable on the flywheel side but really noticeable on the clutch side so that makes me think exhaust leak

 

[Gen1Pat]

You said it was on the left side in your opening post. Which is it? Lol

 

[88WarriorBoy]

Oh crap lol I meant right side lmao

i dunno, but as soon as i heard noises i shut her down and ripped into her. i wouldn't bother riding it or getting a video. start taking covers off and inspecting ASAP!!!!

 

[88WarriorBoy]

well jonS I pulled off my cam cover and even the bearing was tight there was no movement but When I checked timing and I got to the compression stroke I could hear air escaping in the head

 

[JonS]

well, i hopes it nothing but a head gasket. it always pays to dig into things though,

 

[Gen1Pat]

Spray the head gasket area with soap and water and bring it up on the comp stroke slowly and see if there are any bubbles.

 

[88WarriorBoy]

Yeah I'll have to check that But I still can't figure it out why the noise is really only coming from the clutch side

 

[88WarriorBoy]

Alright guys heres the update. I drained the oil and found no metal shavings on the filter. and when I crank my motor over the clutch lever moves which makes me believe that something came loose in the clutch cover but won't know till i have the cover off tomorrow but does anyone got any guesses lol

 

[Gen1Pat]

Could be that basket, the throw out bearing, a broken spring tower(s)...

 

[88WarriorBoy]

Yeah I'm hopin its not the basket lol
