Topic: dyna retard

[johnyvilla]

Does anyone run their dyna timed to the f marks at idle, opposed to the way dyna instructs you to? I recently strobed my 836 and forgot about adjusting it to 2500 at full advance. It ran great and idled lower than it ever had before. After about an hour I remembered the instructions, and sure enough, I was 5-8mm shy of advance, past 2500.

Am I not getting the most out of my bike in this manner? I have had problems over heating in the past and I gather the retardation would help with that.   
Thanks

Hey,

I timed my 550 according to the service manual. My 550 idles around 2000-2200 rpm's. Maybe I should look into the dyna instructions again......However, the bike runs great.

Sheesh. That's high. Mine idles at 850 in its current state.

Yea, I need to go back and time it at full advance.

You'll be way down on power at higher RPM with the timing retarded that much. Idle can be better with later ignition, seems like yours is! I would go with using a timing light to get the advance mark lined up above 2500 - 3000 rpm, make sure the advancer is definitely completely advanced. Just watch the timing marks with your strobe while increasing RPM. The rotor marks will be steady at or near the F mark at low rpm then move towards the advance mark in a shaky manner while the advancer is mid-range and then be stable again, and can be adjusted to meet the advance mark, when all the travel is used up at a higher rpm.
