I have an 07' WR450 that was leaking oil out of one seal . I noticed the small spot on the garage floor last night. I found an old negative and cut a hook in it and swept out the dirt (really cinders from my last ride). I checked it this morning and it does not appear to be leaking . My question is how do I check the oil level in the forks to make sure they are the same? Pics and/or procedures would be greatly appreciated.
