'99 KX250 Rehab (Budget Rebuild)
SOHC:
I thought it was diesel and silicon like CRC spray, I must say I have never used WD40 as its not very common in my neck of the woods
LukeG:
WD-40 is mostly fish oil from what I have heard.
Foxx4Beaver:
could be....as I stated, they could've changed the formula from 30 years ago....but...as rule of thumb, never use rust inhibitors or penetrating oils on working internal engine parts, unless of course the engine's been sitting for years and you need to free something up.
I know I've never seen any top engine builders using wd, crc, pb-blaster, or any other rust inhibitors or penetrating oils as a coating on internal engine parts...they use assembly lube, and/or motor oil...I myself use 2T oil...the same oil that I use in my pre-mix.
Everyone's got their own preference and method, so use what you want...but I don't advise wd-40 or any other aerosol spray.
ecdeyzel:
Sheesh, sorry for the delay guys. Here is a pic of the darkened machined part on the top end. Happened after cleaning. Anything to be concerned about or is it just some basic discolouration?
Foxx4Beaver:
I wouldn't be too concerned, oven cleaner has a tendency to do that to some extent. As long as there's no pitting on the cylinders deck surface, it'll be good.
I would pull the studs though, and lap the cylinders deck surface, and the head as well...just to be sure everything is nice and flat, so you don't have any blown/leaky head gasket issues.
