Need Schooling on Ignition Options

[Fffrank]

I know there was recently another thread about ignition options but it was a bit over my head.  I've got a stock '75 RD350 that I'm rebuilding and I'm close to starting on the electrical.  I've got plenty of experience with wiring and not worried about that but massively confused when it comes to the different types of ignitions, stators, magnetos, coils, rectifiers, etc.

Basically everything is stripped off the bike at this point and I want the least amount of work (and lowest cost) solutions I can find.

Here's what I do know: I'd prefer no battery.  I'll run LED lights.  I'm not going racing.  I'm cheap.  What would you buy?

Help me decide what I need?

i like my hpi. easiest by far.

Another vote for HPI.

On the rd350 racer we just built, we ran it straight out of the box with no other wiring on the bike.

Not sure what it would take to run led lights but I can't imag it would be difficult

i use a basic trailtech 2 wire regulator and run leds on mine.

So -- like I said -- I need educating.  I assume we're talking about this one: https://www.treatland.tv/HPI-CDI-mini-rotor-ignition-system-yamaha-RD350-p/hpi-yamaha-rd350-mini-rotor.htm, right?  $350?

And then I would need coils, rectifier and resistor boot spark plug wires.... anything else?

And since I'm also cheap, what would the difference between the HPI and running this unit https://www.ebay.com/itm/Tytronic-electronic-ignition-for-rd350/192985051350?hash=item2ceece30d6:g:CM0AAOSwrTFdJqdm with the stock generator, coils, plug wires be?

Or this https://yambits.co.uk/rd350-newtronics-electronic-ignition-system-p-23723.html newtronics unit? 

It's a little frustrating that the RD350 ignitions appear to be almost the same as CB750 units with different triggers and backing plates yet they cost 2x to 3x the price.

tytronic has a high failure rate, its a shit knockoff of a dyna anyway.

you can use a dyna for a cb750, a lot of us used to do that back int he day, but you have to mod the plates. its not easy if you cant mod, and they can start backwards.

newtronics and tytonics and dynas require a battery. they are all just basic points replacements. I have a dyna on my r5, its great but 99% stock.

the hpi and the mzb (vape) are full cdi systems, and they come with the coils. the only thing tou need to add to the hpi is a regulator.  they do offer one, ask benji about it on treatland.

I my mind after building RD's for over 25 years, (using most of everything that's ever been made for RD's) HPI and Vape (powerdynomo/MZB) are a great choice...
all the others rely on stock stators systems and battery. (stock stuff is just too painful and old to use, unless a pure stocker and in good shape)
So I'm with Mark and Jim.

Thanks to both of you.  HPI it is!
