Best for cleaning engine ?

[kikasspunch]

I just picked up a 2006 kx 250. The guy bought it new rode it for about 4 hours. He left all the mud on it and never washed it. After that it just sat for years...  I washed it and it shows like new but the engine is kind of tough to clean.  What can i use to make it sparkle like new?

When I cleaned mine off, I had a ton of oil and gunk in the front. I used a wire brush and a rag to get it all off and shine it a little. If you want to make it sparkle, then use some metal polish. Hope that helps

Purple Power... But be mindful of your plastics and seals. It will eat away at that stuff.

Yep good stuff.

 WD40 works good. Let it soak for a bit and use a tooth bush.

I though Purple Power will eat away at the aluminum and make it look horrible? I have only used Simple Green and some elbow grease. It works, but not as good as a grease cutter like Purple Power would, I suppose?

 I used purple power on my ktm 1 time & it will be the last time period!! I now use either simple green or Motorex cleaner & they both work great! The problem I had with purple power is even when I diluted it 50/50 it still left very ugly stains on the rear fender. Luckily I noticed what it was doing to the white plastic fender before I used too much of it on the rest of my bike!
