After I changed my y gaskets tonight, I decided to do the oil change. So while the oil is draining, I headed to the local shops to see if I could find a hex bolt drain plug for the crankcase and the oil reservoir. I took both drain plugs with me. The crankcase drain plug is a 12mm with 1.5 pitch. This bolt I found at Menards. The oil reservoir bolt is a 14mm with 1.5 pitch, This drain plug I found at Advance Auto, which also had the magnet. (I'll keep looking later for a magnetic 12mm now that I know the size). I did use the copper washer on the 12mm crankcase bolt, but used the plastic washer that came with the 14mm, only since the head was so large. Anyway, we'll see how these hold, and I'll let you know if I have any problems. I know I won't have any problems removing them when the time comes.:yes:
