Hard to start 3CL Project with Mikuni carbs

3CL IS NOW RUNNING!
Thanks for all your comments, this has been a good learning experience although frustrating at times.
Turns out it was a very simple fix.
I pulled the plugs and strobed degree wheel while cranking starter. Pointer was showing 64 degrees advanced at 600 rpm!
After emailing with Red I opened the ignition software and set the pick up polarity tab to auto. It was set to negative.
Strobed the wheel again and had 0 degrees at 600 rpm when cranking starter.
I then had a problem with the freewheel and starter gear which was solved with a few parts from Wolfgang.
Once all parts were installed i hit the starter button and boom! Fired right up just like that.
It now starts on the button every time.
I do have a new problem though.... the black ground wire off the voltage regulator/rectifier is getting very hot after only 20 -30 seconds of the engine running. The Regulator/rectifier is new as supplied in Red's kit.
The three yellow wires and the red wire going to battery are not hot.
I've tried grounding the black wire to the engine and the negative post on battery with no luck. ( I had it grounded to bare frame)
I also changed the grounding strap from the battery to engine and am now using a no. 4 welding cable.
Voltage at the battery with engine running is 13.21V . Battery at rest is also 13.21 Volts.
Could this be a bad regulator/ rectifier?
I'm using a lithium battery but the problem remained when I switched it out with a conventional battery.
Any suggestions on what to try next?

Thanks

Tony
 
Anything under 13,8V with a quick starting engine after a few minutes over 2500rpm is trouble indicated, at the battery terminals. Black wire warming/hot is not normal, no news there. Is it the wire length becoming hot or the terminal attached to the black wire? Not an obvious thing to check.

Well done on rectification work and results. HTH j.
 
The wire is getting hot along its entire length. After 20-30 seconds of running it’s hot enough I’m afraid the insulation will start to melt.
 
Best guess, stator current is being sunk by the reg to ground/earth ( 0V ), stuffed RR. Hence the low charging Voltage.....j
 
Not dissing Red here but I also had problems with a Reg/rec he supplied me. Brought a s/h replacement Shindengen off ebay and all is good now.
Avoid chinese reg/recs.
Read my thread "Weird" in the technical section for all things charging. Jon iis_iis is the man to solve the issue. All covered in that thread.
