    Timer

    How many degrees of timing do the old manual timers have? Thanks, Ron

    depends on how far you turned your left hand...unless you have right shift!

    Ron, about the same a auto advance. Full retard is about 5-7 degrees BTC, full advance about 33-35 so the full range is about 30 degrees.. and as stated more than you need as there is no reason to run at full retard. I find starting only needs about 10 degrees of retard max, and most old bikes will start and run fine at full advance.

    Thanks Rob, the reason is, I am making an advance plate for my magneto and I have to mill the plate for travel. This has me thinking a little different, I have never needed full retard either so maybe I'll just mill for 15 degrees. Thanks again.

    For what it's worth the mag on my 45 has been locked on full advance for almost 35 years.

    My Indian 741 absolutely loves retard for idling to the point where I wouldn't consider anything else. It's much smoother and far less "boney" if you will. The effect on this bike is far more pronounced than say my Panhead so I think combustion chamber design etc is the reason/s.

    My UL with SC loves being able to control the timing. On long uphill grinds (3&R trans) it responds beautifully to partial retard. I use the control like a throttle, roll it back to where it picks up and slowly advance matching the RPM. I live at 7000 ft above sea level and everything around me is up, so the manual feature does exactly what it was designed to do.
