Topic: static vs dynamic

[Burnboy]

Im kinda of a newbie on timing. Ive read all I can and thin I have it down but still have a few questions that I need confirmed. Dynamic timing involves a timing light and is done with he engine running, Static timing is done with the engine off right? When I had the top end off of my 750 I aligned everything up so that When I turn the crankshaft  the number one plug fires right as the indicator mark is on the 1.4 line and the same for 2.3 and plug #2. This means Im timed right?  What are the advantages of dynamic timing, ive read that it is more accurate but I dont see how. Thanks in advance.

Static is a good starting place. I have even used a matchbook cover to set the point gap in static mode. But you can't beat dynamic. A good tach, dwell, timing light and you can get your dwell on the two within a few tenths of a degree of one another. then with the engine running, you can get the timing right dead on, including the advance.  Yea.... you will want to do a dynamic check.

I used to do both static a dynamic with the timing.  Now I don't race the bike anymore and static timing is more than adequate.  You do need the timing light to check the advancer function.  But, I haven't noticed any difference in engine power on the street with either a static or dynamic timing performed.

I mostly run the 550's, FYI.

As LLoyd says, if the advancer is working correctly, static timing almost always gives proper dynamic timing, assuming your points are in good repair.
