1954 GF electronic ignition change
« on: 15.05. 2012 23:03 »
Hi folks,
I've got a question that hopefully somebody can help with please...
('54 BSA A10 Golden Flash)
In the photo is what's on (or off in this case) the bike just now. It's a lucas electronic ignition set up fur 12v. What I'd like to do is get myself a Boyer set up but not sure what to go for??
There isn't a magneto on it but has been replaced with a reluctor unit (?), there is meant to be a battery as well. I would like to replace the coils with one of the single ones (as in the Boyer kits) so I can mount it under the tank somewheres.
Is there a kit that would get rid of the battery? Not realy a prob if not.
Anybody any ideas and can ye make the answers simple please... Cheers muchly;):D

Don't replace a Lucas RITA with a Boyer.

Consider a BTH magneto;
Electronic, no battery required, mounts in place of the K2F, and only 2 small coils to tuck away.





Check out their website for more info.

RITA works better than Boyer and even made it onto factory bikes.

Your best choices are: get the RITA working or use a magneto.

Attempting to power a Boyer with a dynamo will make you angry.

The cost in Oz is just over $800 shipped, which compares to about $600 to buy a K2F, and then having it re-conditioned.

Built-in advance, and both cylinders fire exactly 180 degrees apart!
No battery
Mounting holes slotted, so timing can be altered whilst engine runs.

It does look a great piece of kit Richard, no doubts about it.... but a wee bit out of my price range at the moment.
Thanks for letting me know about it tho';):D

I agree, Thanks Richard price is ok if it's said fast with no conversion, but I've bookmarked it for future reference.

Does your present Lucas system give a spark?

I restore K2F's (in my sleep!) so I'm being honest declaring an interest up front. Having said that, I'm not touting for work, I've got plenty of that! Most K2F's go for about £60 - £100 on ebay. There's no point paying any more because you're going to have to refurbish it anyway which may cost up to £150. You could even buy a refurbished one outright for less than £300. Once restored properly you shouldn't need to touch it. I'm sure a new BTH is a great bit of kit and it doesn't need a battery (just like a K2F!). Fitting any other sort of electronic ignition requires a battery (in most cases 12v) so, instead of worrying about your magneto, you worry about your dynamo! I wouldn't dream of fitting anything other than a restored magneto which should be a cost-effective, stand alone, reliable ignition system. After fitting a good magneto you can sell all that other oversophisticated, fangled, 21st century, heap of wires and electronic wizardry (which has no place on a classic bike), and maybe make a few quid!
