Jetting stock motor

[CarvedArt]

I have a stock 97 and I just added a few mods. I'm just looking for some reasonable place to start as far as jetting is concerned.

 

Stock carbs TORS removed idle kit installed

• Mix = 32:1
  Elev = 3222 ft asl
  Humid = 0-30%

 

Base jetting:

• Slide = 2.0
  Pilot = 25
  Needle = Y151, 3^rd groove from top
  Main = 200
  Air = 1.5 turns

...Ran perfect.

---

Added/Modded:

• Switched the coil leads, put the pos on the (+) and the neg on the (-)
  Toomey T5's w/ sparkys
  Toomey 2:1 High Flow Air Filter

 

Toomey says:

• Pilot = 25
  Needle = Y151, 4^th groove from top
  Main = 280 or 270 for higher elev
  Air = 1.5 turns
  Elev = Sea Level

 

My math says:

• Pilot = 25 - 27.5
  Needle = Y151, 3^rd - 2^nd groove from top
  Main = 290 - 310
  Air = 1.5 - 2 turns

 

What jets should I start with? ...Thanks for your help!

I would start out with

Main - 300 depending on temp. 310 if your in the 40deg's

Needle - Middle

Pilot - 27.5

Airscrew - 1-1/2 turns from fully seated.

 

Make sure the carbs are synced or you will have shitty bottom end.

Thanks for the input!

I'm in the 80deg's right now, normally average between 80 - 95.

So I guess I'll start with the 300 Main, 3 on the Needle (middle), 27.5 Pilot, and 1.5 turns on the Air.

As for the sync I've got an EMPI (snail) so I'm keeping that in check too. Thanks again.
