I could use some help locating the rear chain oiler. I can see the hose and follow it back to the fitting but it does not have the lock nut and adjustment like my manuals shows. Right now it just dumps out oil and I want to get the adjustment right. I have read a few post that say to block it off. How do I accomplish this?...just put a bolt in there? How long was the bolt you used? If i put one in there can I run into any moving parts? I need help lol !!!!!
