Work Case #10 Honda CRF150 Seizing

Work case #10 CRF150
-------------------------------------

Previous #9 Honda CRF50

An interesting one this, a Honda CRF150 motorcross bike and the fault: "Keeps seizing".

Well! I couldn't even turn the engine over, but it wasn't the normal metal on metal metal feel but more like the piston was pushing against a big pool of liquid, like, um, I know - engine oil! :shock: :P

Ah that would be it then as I drained out a drastically over-filled engine.


But through the grapevine a new story emerged. Another customer tells us that the owner had drained all the oil out, then his son, the rider, had, ridden it, without re-filling with new oil and wondered why it kept locking up! :shock:

OK so head and cylinder and both side covers off to see what's what, no pictures as there was no damage amazingly. Well, the camshaft was toast and had to be replaced.

I wasn't allowed any more time on it so nothing else was replaced even for precautionary reasons. The longer term effects though, who knows...
