Hi all, been a while since I last wrote, but I stumbled across this. I've currently got a Boyer Micropower on my A50DC, but have never really been satisfied with the advance curve,it just doesn't 'feel' right. Could I run this and power lights etc? Anybody got one? Anyone any experience of this set up?

Hi all, not an advert I promise, but they will be at Stafford show 24th Apr. They are currently developing a system that will run lights as well. Answered my own question really, any thoughts?

"Hits a sweet spot at 5000rpm."
Because that's where it's supposed to be fully advanced, NOT before.

This is the main UK site, currently fitted to trials and scamblers that need no lights, not seen much feedback on them at all so can offer no advice on if they are any good.

Looks like a PVL system. I use them on my race bikes. They work great.

It is a variation to what is standard on a lot of single & twin rice burners.
I used to run SR 500's for work as a metrop courier ( despatch rider for some ).
After about 2 years ( 300,000 km ) the wires in the spark power coil burn out and the stator needed to be rewound.
Basically the kit is a fly wheel magneto.
The big coil on the stator generates the power for the plug coil.
It dose a lot of work on a twin.
The unit probably runs an ac high voltage coil which has a lot finer wire than the standard 12V lump so never test it by flashing it across you battery or you will cook the wires
OTOH timing from the crank is a lot more accurate than from the cam.
Apart from the coil burning out they never gave me a seconds worth of problems and these bikes took a pounding.

Trevor, it does exactly the same work on a single as on a twin...the only difference is the twinspark coil. Unless you ran without lights, it is not this unit. This appears to be either a re-badged PVL or possibly a copy. No burning coils, these are designed for 15000 rpm.

I suspect that Alex is pretty sure that a BSA A65 engine wasn't what he had in mind for 15,000 RPM (or anything over 8,000 as a matter of fact).

But some twins do see RPMs like that, like a Kawasaki 250 Ninja.

If you read Larry Niven's "The Magic Goes Away" and read how the Warlock's Wheel operates, that would pretty much describe an A65 trying to cross 10,000 RPM!

Yes, these ignitions were originally intended for 2-strokes but they can, obviously also work on four strokes with waste spark. PVL makes them available in different combinations of stators and coils for different RPM ranges, the trials versions do not go quite as high in rpm.

And no...I wasn't suggesting a BSA would turn that fast...even though I've pushed the envelope, I know.
