I dont know how to kick a bike (never owned a kick bike before) and the bike just isn't dialed in... takes a few turns to fire up and dies :(

Looking great!


Getting good fuel through, floats set right/working?
What do the plugs look like?

I have no checked the floats myself - PJ did the carbs, so I will assume they are set properly and working. I will do some more checking of that stuff next time I hit the shop

Carbs should only need minor adjustment, fuel screws and idle speed. Idle adjuster will be kinda behind clutch cable. Fuel screws are at 1.5 turns out which will get it started.

LOL, Should have realised. When I was at MMI a lot of people had never kick-started a bike or even seen it done

You'll definitely want to sync them. At least a good bench sync w/paperclip should get you fired right up with PJs carbs and then vac sync once its running. Pretty crucial to a well running twin.

Out of habit from all the thumpers, I usually prime kick once w/ignition off & fuel on to get some mixture in the cylinders, ignition on and another kick should fire right up. If it takes more than 2-3 kicks something ain't quite right.

They should be close, plus, mini ninja has vac adapters for when it's running. Timing is good with correct points gap?

Yes I have the proper adapters thanks to PJ and gauges too.

Timing is spot on, probably perfect. It was very easy once I did it correctly and followed the procedure in the manual. I was trying to do it a way I saw on YouTube and it wasn't at working.

A little late now.
But for what its worth.  Easiest and quickest way Ive found to adjust static timing.

1.  Set the gap on left point to open spec distance.  .14

2.  Now, use your test light or I prefer to use meter on tone so I can hear it open, while watching the marks. 

     Rotate plate til Left opens on LF exactly.  snug plate down & rotate engine counterclockwise

3.  Then WITHOUT using your feeler gauge.  Simply, tweak RIGHT point until it opens exactly on L, it should "automatically" fall within .12-16 specs. 

     Now check RIGHT gap. 

     If RIGHT turns out to be more or less than 12-16, start over w step  1.  This time set Left to open either .12 OR .16 gap...repeat steps 2 & 3.

If you adjust Left throughout the .12 .14 .16 range, opening exactly on LF and find you cant get Right gap within spec opening exactly on L,   

Points are worn out and need replaced.

NOTE>>

If points are set less than .12 they will remain closed to long allowing the coil to heat up and fry.  (not enough cool down time between charging cycles)

If open beyond .16 the coils will have less time to charge = weak spark.

Step 4, start bike put your strobe on it and turn plate for proper operation.  Double check gaps. done.
