i think i got my rotors from bike bandit, ebc supercontour or something like that, good good rotors and far cheaper them oem.

 

I haven't bought anything from here (yet) but the prices on some stuff look inviting:

Kawasaki KLX250S Parts, Performance, & Accessories - ProCycle

Site shows some bearing kits that may be of interest to jhoffy

 

To add to the list - when I installed my vapor thermo sensor the other day, I drained my coolant. I noticed that there were black and gray specs/slivers of stuff in the coolant. I did a few drain and fills with just distilled water but unfortunately it did nothing at all. I checked today after just replacing the coolant and the specs/slivers are back.===============

Dont worry about the the metal particlulates, it is part of the additive package in kawasaki coolant. I drained my coolant in direct sunlight and CRAPPED my pants, i thought something had ground itself into dust inside the motor, turns out the new kawai coolant had the same sparkles in it when I opened the new container. WHEW!

 

Unfortunate for me, I don't use Kawi coolant

I use Honda coolant because it is free of silicone/silicates.

 

I've noticed the same particles. And they linger. Changed coolant last year, and flushed multiple times with distilled H20 after short rides recently and they still keep dropping out. Engine Ice in there now.
