Once I get mine (lunchbox, 40/140, drilled stock exhaust) dialed in, I'll add it.  Then I'll put the V&H exhaust on, dial it in, and add that too :thumb:

Year of bike - 2002
Location/Elevation - Europe, about 300 feet.
Type of air filter - KN Drop in replacement, removed the restrictor to have a little more air flow.
Type of exhaust - Full Aftermarket, but i don't think it is sports. It doesn't sound very mean but better than stock
What size jets you used: I finaly settled on 17.5/60/132.5.  I have tried 135 and 137.5, but the bike chokes on full throttle around 6-7k (although after 7k it was very nice). I had to go down to 132.5 and it was gone. Note: carb syncing helped a bit when using 135, but not completely.

How many washers: I have european model with C clip and 5 positions. I have it on 4th, ( 5th being richest). It feels a little bit rich in mid range, but adds a nice growl when using full throttle on around 5-6k rpm (tested several times changing clips)

How well it runs: Warm up changed only a bit since i didn't change pilot jet. Air screw is at 3 turns. Bike came originaly with 115 jets, so now it takes of from 7k rpm and doesn't want to stop. There are no flat spots, I give it full throttle at 3k and it smoothly climbs to 10k.

I jetted so that i am on the rich side on the limit where problems appear. I believe it is better for the bike. Though fuel economy dropped from 48 mpg to 41. This includes city and traffic riding, with lots of acceleration.

Your favorite food: acetone peroxide.
'02 GS500 Yellow, Mods: K&N drop in w/o restrictor, BSM full exhaust, 132.5/60/17.5 (e-clip @ 4), progressive springs, katana rear shock ('01), fenderoctomy,  sleek mirrors, loud dual automotive horn, warmed grips(home made), SS front brake line.

- 96'
- Sturgeon, PA (near Pittsburgh)
- Elevation: ?
- 1 size up pilots from stock (did it a while ago, don't remember the number offhand...  to 40 from 37.5, I think, but not sure)
- Shimmed needles with 1 #2 washer a piece (again, best recollection, I did the first re-jet three years ago, but remember buying the washers, so I'm sure I used at least one, can't imagine I used 2 with stock airbox and pipe)
- 140 mains
- K&N (Dukes of Hazzard) Lunchbox.
- 2.5 turns out mix screw

Notes:  Runs great, but I cant  tell lean/rich conditions by sound or smell yet, but no dead spots, much improved acceleration and power, sounds growlier through intake, exhaust note is still the same, doesn't smell gassy to me.  The K&N and 140 mains are within the last couple weeks, but the changed pilots and needle were some time ago (didn't mess with them this last time), sorry for the unsureness.  Thinking of getting the exhaust upgrade soon, if I do, I'll be back in the carbs and can validate or refute my claims here on needle and pilots, but 95% sure it's accurate as it stands.  But don't think I'm gonna take apart again just for kicks...hehehe

Also of note, but not necessarily pertinent to this post, however makes bike 'feel' like it has more power (tho doesn't really affect it):  15t. front sprocket (1 tooth down from stock), 44 t. rear in the mail (5 up from stock, I think)
The front added quite a bit to acceleration at the cost of top end.  Rear will do the same.  Expect power wheelies in first once I swap out the rears... if not, I'm chaning the pipes...
BE EXCELLENT TO EACH OTHER!!!!

'94
San Jose/300' above
Stock airbox with Unifilter foam filter
Stock exhaust
40 non-bleeder type pilot jets, 125 large round mains
2.75 3 turns out on the mix screws, floats set to .5inch.
One 0.48mm washer Removed washers in search of better fuel economy; no change in performance.
Warmup time is about the same, but low-end throttle response is better, and low-end power delivery is smoother (even before a Bob Broussard advanced ignition rotor).  Doesn't hesitate at steady mid-range throttle settings (cruising at 50-60mph).
Currently averaging 57mpg.

The motorcycle is no longer the hobby, the skill has become the hobby.

Power does not compare to skill.  What good is power without the skill to use it?

Year of bike: 2000
Location/Elevation: Mexico City, MEXICO / 7300 feet +/-
Type of air filter: KN Lunchbox
Type of exhaust: Stock
What size jets you used (2 numbers for 89-00)... don't know pilots/mains 140(car jets), before tried 150 and 145 (car jets too) but bike smelled like gas station.
How many washers: It has 4 notches and C clip, moved from 3rd to 4th (richest), 2-3 turns out... not sure of set up
How well it runs: Due to local weather never had issues to warm up, after rejetting still warm up ok, however, takes off crappy, bogging a little bit, mid range seems to be too rich but from 7K up the bike pulls deliciously. Mileage went from 43mpg to 34mpg
Your favorite food: authentic mexican tacos, not crappy ones from Taco Bell

Im planning to set needle back to 3rd notch to improve mileage...

  • Year of bike: 2004
  • Location/Elevation: Austin, TX - 600'
  • Type of air filter: K&N Lunchbox
  • Type of exhaust: Stock
  • What size jets you used: 22.5 pilot, 65 mid main, 137.5 main (though I'd recommend a 140), 3.5 turns out on mixture screw
  • How many washers: None
  • How well it runs: Warm up was extremely quick, choke was only necessary in very cold weather. When I did my dyno run I was running a 20/62.5/135 jet setup and the air/fuel graph showed that it was lean all over. I bumped up the sizes of all the jets and it felt much better. Plug chops and subsequent riding showed that it was fine, with a clean pull all the way from idle. It wasn't a strong pull, but it was clean. It started running out of steam towards the top end, so I'd recommend using a 140 main jet. Board member Turd Ferguson used that setup (22.5/65/140) and noted that it felt spot on.
