When do I need an EFI fuel controller?

[Wrench]

My head hasn't been milled from what I can tell and the cylinder porting looks stock.

A stock head has about a 20 thousands lip around the cylinder and I can tell for sure but I would bet that head has been milled.
You dont need a fuel controller with a stock head so that would not make sense. So your good to go with that head.

Can you tell me what your head measures at the step I marked? Looking close up on my phone, my head seems to have a multi angle lead in to the dome, where your milled head only has one angle to the dome.

I guess I will know for sure when I have the engine back together if the compression is in the 140+psi range.

OzarkYamMonster,

I am down here in Sunrise Beach and have a few questions about your settings for the EJK controller from your GP1300. I'm down this weekend if you are around.

Thanks,
Jesse Britain

Hoping this may still be monitored. I have an 07 1300r that I’m just about to throw in the water for break-in. Had 46 hours on it before tear down. Went in for mods and also new pistons while it was torn down. List of mods included and looking for recommendations on settings. Looks like 7-7-7-7 is the best baseline I can find for my setup. Read the entire post and nobody has my exact setup. Thank you in advance.
