Hi all, I need the correct jet sizes for a Hole Shot stage one jet kit for FZ1 I have lost my instructions .. I tried to call but they are currently shut down due to cancer issues..... Right now I have 130's and 127.5's........
Thanks,
Nate
 
The FZ1 was lean on the bottom and rich on the top, so the jets are actually a little smaller to fix the top end part.

I guess this was the quick answer from the Bandit files document:

FZ1 carburetors are odd in that the main jet sizes are not all the same. In #1 and #4 (outer) the
stock size is 132.5 and #2 and #3 (inner) the stock size is 130.

The Holeshot kit calls for a 130 jet in #1 and #4, and 127.5 in #2 and #3. However the kit does
not include 130 jets, so the 130s from #2 and #3 end up being swapped into carbs #1 and #4.
Then the 127.5 jets from the kit go in #2 and #3.
 
Nate,

way back in 2012 I put a stage 1 jet kit in my 2005 FZ1. I live at 8000 feet and ride mostly there and above.

Per Dale's high altitude recommendations I installed 125 in #1 and #4, and 122.5 in #2 and #3. And it ran great.

I traveled to Laguna Seca to watch the MotoGP race. Before the trip I asked Dale if I would hurt the engine.

He said "Nope don’t touch a thing Jim, it will be fine. Great chance to run a bottle or two of carb cleaner through it on your tip though."

This wall of text probably doesn't address your question, just my experience with Dale and his kit.

I would say stick with Dale's advice. The jet size controls full throttle conditions. That is where the bike runs rich with factory jetting. That's why Dale's jets are smaller. The jet kit fixes the overly rich full throttle conditions and the lean low throttle conditions.

Idle and low throttle are handled with the. Needle shims and the air screw. With the factory jets, the bike runs really lean supposedly to pass emissions better, I hear. By shimming up the needles and adjusting the air screw (I think it was 3.5 turns out, but check the Bandit files), the low-throttle conditions are richer, so it's all balanced out. All I can say is that my 2005 team like a striped ape with the timing advancer and Dale's kit default settings. My fuel mileage went up as well.

I think he got it right.
