Hi, Dose anyone know what the Big end float should be for a 2003 125cc rev 3 please.

I give up.  What is a “Big End Float” 

Bite the bullet and replace the mains.

Ah, ah you mean clearance, wink, slop, free play,  je suis savant!

Yes I have replaced the Connecting rod ,but there seems a lot of end float, dose anyone know what the free play should be    

dont know about the 125 beta specifically but around .007"-.0010" is normal 

Paulc 76     Thanks for that.

 

I have always done my cranks at 18 thousands. Beta only gives a spec for the two halves total distance. 62 mm: +0.05 to -0.15 mm. I always looked at float being play in the whole shaft. Rod set up was a different manner. That is Beta specs from the manual.

Thanks Lineaway for the INFO .
