This will be my first post. up until this point i have found all the answers i needed without a post. This is a great site . ok here is my question... From what i have been reading the small hole on the block is the spark plug drainage hole is that correct? After riding my bike (00' 426 no modifications) there is a small amount of dark liquid could be oil coming from the hole, it is only enough to make it a couple of inches down the block.. This is probally nothing but just wanted to check and make sure. I bought the bike used about 3 months ago. Any and all input would be greatly appreciated.
