Title: 1990 KX125 Bottom End
Post by: mexbiker on May 24, 2013, 10:49:32 AM

Hi there - bought a '90 KX125 for me a year or so ago, but decided that Motocross is for younger guys than me - switched to trials and my 15 year old started to ride the KX125, doing far faster lap times than I could ever do! That was until the motor seized. We have taken off the head and barrel and found what I am guessing are the remains of the big end bearings. Have not yet been able to "persuade" swing arm pivot bolt to budge, but when I have and have split the cases, I am guessing that there will be damage to the crank. Looking on the Net, I cannot seem to find any big end assemblies for KX125's older than 2003 - anyone know if these are available?

Cheers!

Richard
