Oil pan removal??
 

I'm looking for the best way to drop the oil pan in my 2002 F4iF4i, it has an oil pickup for stunting but the previous owner didn't seal it right so it leaks a little, from what I've seen it looks like I have to pull the radiator to get the headers off, which isn't something I particularly want to do. Any help would be greatly appreciated, thank you!

^ He is right. You just have to undo 2 screws to detach the radiator from the frame. You need a long T wrench to get the top one out and then a regular one to undo the bottom one. The would just suspend itself using the hoses. Just force it down and let it rest over the mudguard/tyre. This will give you enough room to get the headers out
