Many thanks to the posting on changing the oil. I did loosen the srcew on the head to verify top end lubrication. Wow what a mess. I loosened the screw of couple of turns, nothing...couple of more, nothing, took it all the way out, oh yeah! we have oil flow to the head, dang what a mess. I do have it all cleaned up now, ready for more riding. These darn newbies have to learn the hard way. Again Thank You all for this forum and all the expierience, with very helpful tips to keep the my machine running perfectly.
