K6 1000 engine squealing

Am I looking at some bearing scuffing?

Maybe check the clearances with Plasti-gauge?

Hi man
Checked it... within range,this is a used engine I thought same...but why squealing after that mileage? Worst crap should be fresh on not after doing over 1k miles, will update soon after doing other plasti run after fully cleaning seals and oil

The "squealing" description of the noise is strange. I would expect severe bearing damage if the noise was coming from the main and/or rod bearings.

When I hear that noise description, I usually think of the stator area first.

I don't know anything about the internals of one of these motors. Never had one apart, but are there any ball or roller bearing within one of the motors?

Yes, in KTMs.

Have you pulled the engine apart again already?

Did you try and locate the source of the squeal with a mechanics stethoscope?

My guess would have been stator too although to me that is more of a whining sound.

Hi guys

Yes before pulling I used the estetoscope to hear, the squeal is only in cold and would even stall the engine, once warm no problem and the weird thing....no power loss

Have cleaned the casings for now...might also pull the head...if don't have to better...saves me a headgasket
Measurements are ok with the plasti,the thrust bearing are also fine,no marks on crank

I'm using the schnitz uprated oil gear and releaf valve,also a flo reusable oil filter now

I'm curious to hear what you determined the cause to be.
