I did my own 600 mile service today. I was going to use full synthetic oil like I use in my Valkyrie, but our manual states using a higher grade oil may cause clutch slippage. So I went with 10w40 Yama lube, it should be fine. I have not had to adjust a drive chain/belt in over 30 years- had shaft drive bikes. The manual is a little confusing. I did buy a belt tension gauge and finally figured it out. Heck, back in the day, I would adjust a chain just by feel. I had to move the wheel back about 1/3 of distance between the third and second hash marks from the rear of the swing arm. Does that sound okay? Anyhow, I now only have about 1/4 inch play on the belt with 10 pounds of pressure on the belt. As far as fuel injection synchronization goes, forget it. Creating a makeshift gizmo with hoses, boards, graphs, fluids,- I am not Dr.Frankinstein! As long as the bike runs good, I'm good.
