Loud Mouse knows what he is talking about, but I don't know what he said or what you actually did. Timing is usually set at the timing mark and that's about 5 or 10 degrees before TDC. Some people like to set static timing in the fully advanced position and to do that the crank is turned to the full...

That happens to be what most 4 cylinder bikes do, so you can use an electronic tacho from almost any 4 from the seventies or eighties. I have used tachos from...
