Hi all ,
Anybody has tried using ignition booster/amplifier for increasing spark density ?
Am going to increase the compression of my bike keeping the points ignition which kind of doesn't work well on high compression engine and I don't want to go CDI route .
Something like this ?

Please suggest.

get a hotter set of coils.

Hey , how can I decide on hotter coil ? Any specific values ? We have 4 ohm primary and 13k secondary coils in India came with bike
im not sure w the radjoot ones were rated at.
Many years ago, we used to use transistor assisted ignitions. The idea was that the points would be subject to a much lower load to just switch the transistor and the electronics would carry the load. To be honest, I can't say that any change in performance was noticeable. Maybe try a relay in the coil power line to get full battery voltage to the coils. That won't help your points last any longer but should potentially provide a stronger spark.
You could also try a set of Chinese DYna clone ignitions. I am a fan of Dyna and not of companies copying their IP but you are a long way from here and that might be a suitable solution for you.
^ solid plan
Im currently using the Chinese dyna. I had several real dyna burn up due to leaving the ignition on. Works fine and it was a fraction of the cost.

Funny you should mention that. I was setting up a custom DYNA for a GT550 triple and three genuine DYNA modules let the blue smoke escape as I was setting the timing. Not all at one though. One dies so it was replaced then a different unit died and was replaced.
Copycat units, no problems and what appears to be a fatter spark on the tester.
That was a pretty common with Pertronix pickups too. Leaving them on was asking for it. Pertronix fixed that like 15 years ago.
