Otherwise surely suzuki would have done it in the first place.
"There's no such thing as a free lunch". There are always tradeoffs. I'd just like to know what the negative part of the trade is. Anyone know?

The one thing you can count on when buying a carburated bike in the US is that it will be on the lean side for fuel emissions. One step fatter has been my norm for any street bike I have bought in the last 35 years. If a bike is coldblooded....that's the first clue.

So, basically, you're implementing the same thing as permenant "slight choke" on all the time?

but it woud cause the thing to fail a california smog test?

Where did you gett the jets from???

I went to a local dealer and ordered them there (same sizes as Stevo mentioned, also listed for stock bike on Wiki). I looked for part number on a link off the Wiki page and the dealer ordered them for me. Cost me around $15 CDN for the set.

1. The 80's and 90's and 00 vintage Bikes are setup lean from the factory AFAIK.
2. Some bikes both models and examples in each model are worse than others.
3. Mod anything in the system and you're likely to need a rejet.
4. Trade off is yes, loss in the cleaner emissions, a shade lower gas mileage though a nicer running bike will result in you twisting it more and hence getting even less gas mileage.
5. The needles and floats wear to the richer side and in some bikes like vulcan 1500 and a few other I dont remember right off hand, the needle will wear so much it needs to get replaced every 10-20K miles. Floats on an 89-00 lose adjustment every 2-3 years depending on the bike/use/luck.
6. Leaner = hotter and you dont have a reference point to measure it. Maybe someone should do a control test. It could be as much as 100 degrees chamber temperature. There gotta be a correlation to exhaust temp and someone oughta install one of those and try it.

And -

Here is the kicker ... and why I got in the rejetting racket.

Suzuki, the same suzuki that "would have done it in the first place" sent out bikes jetted with 40/125's and an adjustable needle to boot in contries that had no epa. Canada england and a lot of europe in the 89-00 series got 40/125's as did most of asia and australia. Look in the manual for a list of countries and what jets they got in the bike.

That IMHO to a pencil pushing software engineer is a dead giveaway that the "best practices" are not followed here.

The 01+ jetting calculations are just an extension of the 89-00, do a +1 all across and try it. I am yet to see a true 01+ manual.

Cool.
Buddha.

Regret: not getting started in the dirt. 20 years ago, instead of 5 years ago on the street.

Mistake: lots of them, learned so much on the gs.

Best advice for new riders, slow down, look for everything, and ride instead of modding.

Maybe they're a company that thinks that sticking to "environment protection"' standards (ie: "protecting the environment) is a good thing, even when not required to do so by law.

or maybe I'm just crazy.

I regret buying GS, this little piece of underpowered crap makes me shiver when it doesn't want to start in the winter due to stupid carbs. I should have gone with liter bike in the first place and skip the learning part on the 500 all together.

Just kidding, I love my little yellow bee

What I regret is drilling the stock exhaust years ago. It sounded like retarded lawn mower I later replaced it with stock GSXR pipe which I also regret because I spent $50 on it ant it looked oversized for GS500. I then went with Leo Vince SBK oval and love it (I already had custom built flange so installing Leo took 5 minutes)

I know and they love the USA so much they sent the least polluting bikes to the US ... y'know air never moves across from one place to another.
Its jetted 1 size too lean due to epa that is it. Besides they know murricans will never ride it, and if they do, they will spend tons of $ @ the dealer to "fix" their problem.
Cool.

I've made a lot of mistakes while wrenching, and learned a hell of a lot from each one of them. The biggest lesson I've learned, over and over and over is to due diligence in everything. Sometimes there are shortcuts, but if you're going to use one really think it over - often a shortcut will cause more harm than it's worth.

On the BMW, I tried to bolt down the cam caps without the correct tool. Might have worked fine... Might eventually find that I ruined my cams and bearings, worst case is that I'll need a new head. Not worth it to save on a $100 tool.

On the race van, I pulled the front of the engine apart and oil pan off before double checking that the timing rotor wasn't out of phase with the crank. Now, no oil pressure. Created hours of work for myself.

On the GS, I forgot to check the oil after a couple of trackdays, and then rode on it with a small rattle from the engine. Result was one busted up bike and a dislocated shoulder.

Check everything. Confirm everything. Don't ride on a vehicle unless you know that it's 100%.

First mistake - not going to GSTwin site to read posts on the do's and don'ts of changing oil.  This led to the second mistake of over tightening and snapping off the cap nuts holding the oil filter.

Regrets on Flick tried going LED on all the turn signals what an electrical pain finally just went back to incandescent except for indicator lights.

The rejet I did when Buddha was being "nice" and sent me jets I never even asked for. Worked fine for a bit but 9 months of hell so far and counting.
