regarding curves, you referring to the HPI i assume?

Considering the available technology and how cheap electronics have become across the board, seems to me accessory electronic ignitions are WAY overpriced.

A racer friend in Dutchland made his own Yamaha TD1250 ignition out of OTC chainsaw bits for almost free; any small-engine repair shop usually has buckets of these ignitions that have been salvaged and sell them for a few bucks if not free.

Included is a picture of his $50(in Euro's) race ignition - 10,000rpm all day and never misses a beat. The cost was engineering the rotor mount and backing plate.
 


As I recall, his setup used a Husqvarna 2-cylinder chainsaw sparkler. There are many smaller ignitions that could be made to fit inside a cover.

i used to make them out of car ignitions, there's a million ways to do it. getting it to fit, correctly,  is the issue. getting a charging system thats ok for the street is the other.  just depends what your time is worth. for under 300 bucks, an hpi is a hell of a deal for a bolt on (mechanically) with an igniton curve. thats what went on to the harris race bike with the rotax motor, and i basically had an open checkbook for that.

For sure on a road race bike, a self generating system such as FEMSA, Motoplat, HPI, PVL etc are a no brainer.  For the street where 12v is needed to run lights etc, something like a VAPE is ideal and anything that replaces 50 year old electrical components has to be an improvement. 

For a drag bike, an RC 14.8v battery and DC-CDI is a great set up.

Funnily enough, for the street I prefer an internal rotor generating system with a DC-CDI programmable ignition and that's a different ball game.

He ordered an HPI.  I think spending the money is probably worth it in the end to get something that has been proven out.


Those front tires are similar but upon a closer look they are definitely not the same.

I was talking about the V shape in tread pattern. 1 bike has the V facing forward and 1 bike has the V oriented rearwards?
