I have the 4 injectors back that was original in the car from FIC and the other 6 that I had locally.
Product Font Material property Technology Cylinder


Results of the 6 and 4 respectively for easy viewing:
Music Font Parallel Musical instrument accessory Paper
Font Parallel Paper Rectangle Number


Two options I'm looking at is running the 4 that are rated at 358 or the 4 higher values with 364 installed on cylinder 4 and 361 installed at either cylinder 1 or 3, leaning more toward cylinder 3 but I'm also debating on putting the highest one on the cylinder that will have the o2 on it and figuring it out from there.

These numbers are all minor respectively but its that nit picking that has me going, inputs...

Also thinking of two 358s on 1 & 2 and two 360s on 3 & 4...

Thats a cool test. I would think to run all 358. Not sure if the O2 will jump alittle more with highs and lows rated injectors but that might be a negligible difference.

I'm going to run the 358s, was going to do offset to adjust for heat/temp differences between the cylinders knowing that 3 & 4 are the hottest but I'll save the experiment for later if I feel like it. I'll post the rest of them for sale later.

Thats reasonable reasoning but I still think its too small of a difference to tell even for an O2 to matter. Just gotta live with the QR25 life's up and downs af far as heat. I never knew that about #s 3 and 4 tho. Clutch heat absorbtion?

Look at the head gasket failure, mostly from heat and the coolant wouldn't be as cool as cylinder 1 & 2 comparatively, thermostat/water control is right there at cylinder 4 and the last to get "fresh" coolant. Its minimal but its there.

Looking at the fueling and ignition of each cylinder on my bike, its value differences are small but it accounts for intake and temp as well with 2 & 3 in the center while 1 & 4 are outside "sharing" heat on one side.

I understand that. A little bit can go a long way over time
