Here's a teaser. Will try and do a GoPro edit during the weak.

 

solid effort 

I’ll pay that one 😎

Right new theory, as my stutter/misfire is quite inconsistent now and only happens at certain times.

Only does it when it's hot. Like proper giving it a hard time.

So either A.
Heat soak. Probably quite likely.

Or B. Fuel Cavitation when the second fuel pump kicks in. The reason I say this is the Hobbs switch I had here has a minimum setting of 10psi (and I have it set to 12), which is around when this stutter occurs.

Or C. Coils are still I <3 Bananased and get worse when it gets hot.

it could be because the switch and extra fuel pump are taking more current from the system and your spark is suffering?

Run the second pump all the time or set it to come on at a couple of pounds so you can diagnose that part of it. What keefy said can be taken into account here too.

 

Get a giant single so you don't melt the motor if the second one fails.

Yeah all could be right.

I'll get a new Hobbs and bring it on early like your meant to.

What pumps are you running? I haven't read your whole thread yet.

Raceworks 044 equivalent. In bay surge tank

Plenty of things to check ay.

Get a better alternator and battery.

 

Problem solved

 

Trust me, I'm European.
