Hmm. The 2 marks on mine seem to be at 1 o'clock and 11 o'clock of your mark relative to the HPI engraved on the face of the rotor. Anyway I've run out of brick and mortar stores trying to locate the 7mm bolt to mount it to the crank. Gonna have to get it online. Need hardware to mount the stator to the plate still too.

These are the only marks I can find. Nothing on the side or the top. Do i just transfer them up the side for visibility?

More "shelter in place " work on my basket. Couldn't find 7mm hardware to mount stator but finished up wiring and got it mounted temporarily. Found the rotor has no markings to set timing tho.   

Got sent home because of the "shelter in place" status in the Bay Area so I re-wired the HPI stator to run without a battery. Thanks M in Sc. Pulled the old ignition off and got the HPI in place. Need to get some hardware to mount everything still and find the locations to mount the other bits in the kit. Beer:30 now so I'll clean up the shop and run around tomorrow for hardware Ace will be open. Should be nice to get out n ride around town with fewer shitty drivers on the road. Then hopefully back to work thursday .

Yeah the plan is to run without a battery. Thanks for verifying the connections Mark. I feel much better moving forward with this now. Basically want to run head light, tail light and brake light connected to both the front master cylinder switch and the rear brake switch and kill switch. 

disconnect the one winding ground, run that up to the main wiring coming out of it, run that wire and the original lightning to a 2 wire regulator. its super easy to do.  then, you get full wave ac with more than enough power 

so in my case disconnect the bare wire and solder on a new yellow wire and do a 2 to 1 bullet connector to the yellow from the reg. and brown is power out?

just looked a the trail tech instr. wire one yellow to yellow the other yellow to the brown and put switches in-line?

that's the one i have.

however,  one goes to the yellow, other goes to the other leg of the ac coming out after you float the ground on the back of the cdi unit.

the wire that is on the back of the unit that is held down with an eyelet? you need to unground that and run that wire up to the other leg of the regulator.  this gives 2 ac leads out of the unit.

so the unit i have has the black wire with an eyelet  (that joins the blue and white in the plug)  under one of the allens that mount the windings to the plate. then there's a bare wire from a winding soldered to that black wire.
 
thanks for all the help

running led bulbs on mine, just using a trailtech voltage regulator. I floated ground on the unit, so 2 ac leads out. both legs to each leg of the voltage regulator, no rectifier. one of those legs goe sup front powers the headlight and brake and speedometer. othe rleg goes back and powers the tail light. I run nothing else on the bike, been fine for well over a year.

will say, one of the led headlights burned out immediately (had the internal fan), but the last one has been fine (no fan). must just be manufacturing differences.

Thanks for that. Looks like I got the wrong regulator maybe. Mine only has a brown and a yellow. Got it on the bench now. Seems pretty straight forward. Orange from cdi to coil pack. plug to plug from stator. Black/white to kill switch. Yellow is for lights. Correct? Also the soldered joints on the back of the stator are epoxied over. Whats a good somewhat stylish kill switch? Did a quick look and nothing caught my eye. What would be the best regulator?

There's not a lot of HPI install info I could find.
So this is what I went through for Mike's RD350.
He brought me his bike together but no wiring on the bike as the stock harness was taken off.
Mike did have everything mounted with the cdi and regulator.
I added lots of engine and frame grounds, then built a bare bones harness for just lights, brake lights, high and low headlight, charging system and tach power.

The hard part was where to set initial static timing as the HPI website showed setting it using a scale whether using clockwise or counter clockwise rotor rotation.

any chance you could draw up the "bare bones" wiring diagram? i've been tryin to get nick's ignition to work with the oregon motorcycle parts r/r without any luck.  just got the hpi from treats. so i figure on wiring from scratch. also is it possible to run the hpi without a battery?
