Is electronic ignition the way to go?

[KeithJ]

Just to clarify, there is no additional gizmo, this battery has its own internal “circuitry” which ensures each individual cell is charged and allows “normal” chargers to be used.  Hence, it may be ok to use on the type of charging system our bikes have.

G'day Keith.
The main problem with Li batteries for us (A7 & A10) is the narrow charging rate (As with all battery types, over charging and severe discharging will damage your Lithium battery too. Always check that the charging voltage is limited to a voltage below 15V but above 14V. As for the battery, you should not let the voltage at rest fall below 12.8V.) copied from their site.
A mate killed two of them in his HD, replaced with an AGM and all is fine.

Correct. 

Interestingly taken from the DVR2 web site:

"The regulator output should stabilise at 7.2 or 14.2 Volts as the speed is
increased"

https://www.dynamoregulators.com/documents/dvr2-data.pdf

I don't know enough to say if this regulator spec is typical of regulators.

So could it be possible to use it with a Skyrich battery with the right regulator?

G'day Keith.
DVR2's are the ducks guts, I have'em on both mine (12v electronic ignition) but AGM batteries. The weak point is the dynamo. Up the speed with a belt kit.

I live near the Mike who makes the DVR2's and have one fitted along with the belt drive.  So all good there.  Did a complete engine rebuild 5000 miles ago and fitted electric start.  Goes well but am now about to look at third mag "rebuild" as currently have oil in it.  So frustrated with the mag issues and looking at electronic.  Trispark looks favourite but getting expensive as is the BT-H modern mag.  Trispark does not have an additional box to hide which is an advantage.  What electronic system do you use?  Looked at Thorspark but don't want to rely on using a strobe to set it up.  Bit of a pain having to remove the primary side.  Took my original mag off the bike just before the rebuild, about 4 years ago and it was still working.  Had the A10 for 50 years or so. All the best

G'day Keith.
Boyer in both (51 A7 and 57 A10) for about 20 years, set and forget. Both have permanent degree disks fitted for the strobe light. The A10 is open primary so only takes a few minutes. The plunger only gets checked when the cover is off once every couple of years (will be soon as the clutch is dragging).

Been put off Boyer as can be voltage sensitive.  I guess you have not found that a problem?  Interestingly, someone gave me a very old Boyer ignition kit.  Probably the same era as yours.  All the best Keith

G'day Keith.
Yes they are sensitive to voltage. When it drops to under 11v they go full advance. I run a 4 amp AGM that will give me about 1 hour riding after the dynamo quits.
