First Look
« on: May 21, 2018, 08:42:41 PM »
We picked this good looking used 2013 YZ250 up to document the process of inspecting and refreshing a used bike.

Longer term it is going to be a "test mule" for product tests and will be part of a really cool, but as yet to be announced, series. 

Stay tuned.

Fork Service Surprise
« Reply #1 on: May 21, 2018, 09:09:17 PM »
I started on the tear down and evaluation. No surprise the fork seals were leaking, I noticed that when we were evaluating it.



This was a bit disappointing but not surprising,  the original owner said he never serviced the forks.


This on the other hand was a completely unwelcome surprise.


From what I learned exploding free pistons aren't all that uncommon. Supposedly they fixed this after 2009, but this is a 2013 so draw what conclusion you will from that.

The upside to this is that a couple of different companies makes aluminum free pistons for it that are open on the sides to prevent the over pressure that causes this failure.


Next time I will show you why it is important to take your brand new bike apart before you ride it.
