Pulling off fairing panels revealed this ignition advance and rev limiter. Can anyone ID this unit? The advance is set to 5 degrees and the rev limiter to 9500 rpm. The cylinder head says 1250, the tuning shop billed for a 1300, according to the paperwork. The work was by original owner and the shop ain't talking, so I'm left with a bunch of questions. Oh yeah, the Dyno peaked at 94HP. K&N filter, stock pipes, and no clue about the jetting.
It is a Dyna 2000 ignition system. You can find the instructions here: http://www.dynaonline.com/skins/downloads/instruct/DDK7-1.pdf (http://www.dynaonline.com/skins/downloads/instruct/DDK7-1.pdf)
The 1250cc engines are commonly called 1300's - so I wouldn't be worried about that.
That seems like a low dyno sheet - even for a Factory Pro dyno. If you are within a full days drive of RPM I know where I'd take it without a second thought. RPMRacingca.com
You'll find plenty of excellent reports on Randy and Robert at RPM.
Good luck!
Edit - if it's a Factory Pro dyno - 94 with stock pipes and airbox doesn't sound off the mark
The advance isn't 5 degrees....it is on the #5 advance curve which has the slowest total advance curve. Initial timing is probably 35 degrees or so. You might want to try the #2 curve
Thanks guys for the info. I will read the directions. Usually I only do that when I have parts left over!

I'm sure you meant to say Total Advance[iof 35 degrees

You're right....thanks for pointing that out! Initial is 15 degrees if memory serves me correct.
So I read Dyna's instructions and it looks like JMR is correct about setting #2 for the ignition advance.
Can I just switch the knob (with the ignition off), or do I have to change anything in addition to that?
Ignition timing and electronics are above my pay grade, so any help is appreciated.

Yep - its that simple - just change the setting. It "loads" the curve setttings and retard setting each time its powered up
Well, I switched to position 2 on the Dyna 2000 and it feels like a different machine.
The sweet spot occurs at lower RPMs and feels more linear, less peaky.
The powerband is right where I want it to be.
Hard to explain, easy to feel.
Thanks for the help, you guys are great!
