Vape powerdynamo 277 install

Hopefully someone who has recently installed a 277 VAPE will chime in then. Got to love conflicting information
That really has nothing to do with the Vape, and all to do with how the crank is set up. The spark will happen when the "hump" on the flywheel triggers the pickup. So it is just a matter of matching the pickup to the cylinder approaching TDC on its compression stroke. In any case, one cylinder will fire, then the crank will turn 277 or 443 degrees before the other fires, all depending.

Thanks for the reply. That’s what I am trying to determine - which pick up to set the initial timing at before first start up.

Left cylinder in TDC compression stroke, should I use the top or bottom pick-up to set the 43.6mm spacing

That depends on how many degrees later the RH cylinder is at TDC.
If RH is at compression stroke TDC 277 degrees after the LH one, then LH cylinder should fire from the upper pickup.
If the RH cylinder is at compression stroke TDC 443 degrees after LH is at TDC, then LH cylinder fires from lower pickup.
Note that there will be a spark EVERY crankshaft revolution, i.e "wasted spark"

Left cylinder is usually the top trigger from what I can gather trying to read the instructions.

The directions are so misleading. One picture has it with the top pick up while the next picture has it with the bottom. Hood racing says it’s the bottom

I’ll get out in the garage this week and see where the RH compression stroke is compared to the left
 
I'm fitting one to my project bike.
As I understand the poorly translated instructions, the left cylinder is #1 & that should be the top sensor, so long as the #2 crank half has been rotated forward 83 deg which is the most common. Set it up using #1 left side as standard & it should be OK.
 
It's been 8 months since I installed and timed one; haven't touched it since and it runs superbly. As you got conflicting info. from a selling dealer, it has me questioning what I did.

Who ya gonna listen to; some random guys on the internet? What does Revival ATX (seller) or VAPE vape@vape.cz say?

Just do it....;)

The ONLY 100% reliable way, is to personally verify how the crank is rephased, and take it from there. There is absolutely no way Vape or their resellers can know what Hugh or other engine builders have been up to. So they just cannot say anything about this.
So, back to basics, it is really not that hard.

Ok I spent some time today verifying TDC with a piston stop and degree wheel.

I can confirm that the RH compression stroke TDC happens 277 degrees AFTER the LH compression TDC. Therefore the left hand cylinder using the TOP pickup on the stator plate. Correct?

Now with timing I measure a 43.6mm space to the left (looking at the left side of the engine) of the top pick up metal core (left side of the metal core or the begging of it) and the beginning of the ridge on the stator?
 
If you cut a piece of paper 42mm long and position it between the right edge of the raised trigger strip on the rotor and the left edge of the metal pick-up sensor you'll have 40 degrees at full advance.

The "charge control" at pin 6 (green/red wire) is to be from the reg/rec to an indicator light (optional, voltage unknown). The red at pin 5 is charging current from the reg/rec to the battery (in your case likely 14VDC). There is no switched power to the VAPE ignition or charging.

Question about the coils. There are two ground symbols. I’m guessing one is the ground through the spark plug. Does the other one (circuses in picture) mean that I should mount the coils to a part of the frame with a clean ground?

The second ground appears to be the coil iron core that is grounded. So yes, a clean frame ground is required.
Thanks. I drew up a wiring diagram that I think will work with VAPE and the m unit. See attached. What do you think? All other connections not listed are as follows from the VAPE directions.

Question about the kill switch for the coils. Can this be a momentary push button or does it have to be a constant switch (once switched it stays closed to ground until opened again)?

Let us know when you get it running and what you did (top or bottom pick up)!
 
does the ground switch for the "kill" to the coils have to be a constant switch or can it be momentary?

Constant would be once you switch to ground, it stays grounded until you switch it back, momentary just temporarily grounds

Either will work. You may have to physically hold the momentary a second, but will work fine.
