Is my bottom end bearings bad?

[99blasterzach]

No top to bottom movement
There is left and right

allso as you can see the crank is like burnt and has blue like it got super super hot

The blueing is normal. It's heated during assembly.
The manual has specs for side/side clearance and small end play.
Double check but IIRC side clearance is .028" MAX !

0.28" is for the con rod play from left to right?
In my manual under 4-24 is this what your talking about?

*****.028" NOT .28" BIIIIG difference lol

 

[Larry's Shee]

.028" is feeler gauge between rod and crank journals.

For a minute I thought I posted .28" Some things are hard to explain without copying from manual, plus pics/diagrams are worth a thousand words.

Did I mention Clymers Repair Manual or online manual yet ?? There's a link on this site.

I have the Yamaha "yfs 200 service manual " it's from Yamaha

So what I need to look for is "big end clearance D"

 

[99blasterzach]

I just looked at my con rod and it say "Hot rods" so I'm thinks that that's not a stock con rod

Is this a plus 4mm rod????
