Today I focused on the AP timing, opened the cover, read the service manual (SM) and attempted the operation. I found the SM to be very confusing. If the adjustment is made to my interpretation of the SM, the AP does not function at all. The SM says, "insert the 3.10mm rod", I did. "Fully turn the AP adjustment screw. Check the link lever 4 has free play by pushing on it slightly. Gradually turn out the adjusting screw while moving the link lever until it has no more free play". Well, as I understood it, I backed off the adjusting screw until there was no more free play in the link lever or the push rod link lever assembly. This meant that the adjusting screw was just touching the link lever. This also meant that the AP was at the bottom of its stroke w/ nothing to pump. The SM illustration show a finger pushing the link lever to the front of the bike while making the adjustment. As I twisted the throttle, there was no visible squirt of fuel. After reassembly & try out, the bogg was terrible. Taking a WAG, I turned in on the screw 1 1/4 turns and tried again. Much better, much less bogg. But still not right. I have to understand this and I don't. Please offer some direction. I have spent hours searching these forums for some clearer discriptions of how to do this. Also spent hours looking for a good description of how to do the BK MOD. All I have found are testimonies of " Wow, the BK Mod is Bad @$$."
