My 250 narrow case is extremely difficult to start and is killing my knee when I try. It has no Auto Advance Unit.

A while back I purchased an AAU just for this reason, perhaps off eBay.

As I was getting ready to install it, I found a thread that indicates there are two different AAUs, one for DC "AA359" and one for AC ignition systems.

My motorcycle is running a DC ignition.

I hoped the AAU I bought was a DC one, but this unit has no markings on it whatsoever.

Does anyone have a DC AAU "AA359" they can sell me? I'm located in the US.

Thanks,


Jim

Hi Jim,

What about ditching it and buying an Electrex World ignition system?

Cheers,

My knee-jerk reaction is that it’s a lot of expense given the monetary conversion, international shipping and tariff costs.

On top of that I’d incur the secondary expenses and potential for other issues converting from 6V to 12V.

If a simple AAU implementation fixes my hard starting issue, it’s a fast and potentially inexpensive solution.

I’ll keep your suggestion in mind but I will reserve considering it seriously only if faster/easier solutions don’t work.

I do appreciate the suggestion.

Hi Jim , i think the Monza AAU is the one that is commonly around . My 250 M3 has one and does not kick back .

Jim,
The photo you posted of your auto advance is correct for a DC/ battery ignition.

Thanks Jon and Bob. I will install the AAU and hopefully solve my kick-back and hard-starting issues.

Hi Jim, I set the timing up so that its about 5degrees before tdc when static . Seems to do the job. Still looking for a set of swan bars ,too old for clip ons now.
