Hi all,
So 2001 with about 4500 miles. wouldnt idle right so i pulled the carbs and found them all gummed up and full of crap. It currently has the stock jets. While I have it apart should i rejet? Its stock so what size jets and where can I get them from? I havent been able to find a good indy around me and the dealership is kind of a pain, and expensive.

stock jetting should be fine as long as you have a stock bike... if you need a bit of a tune, drill out the air/fuel mixture screw caps. and mess with those.
A stock bike should be rejetted to 1 size over - cos they did that in countries where there was no EPA.
The numbers are 20/132.5/1 washer/3 turns.
I sell these, but am out of pilots now, and anticipate getting it later this week.
Cool.

I bought my 02 GS in Sept 03 with about 4k miles on it and it now has over 100k miles on it. It's been ridden mostly around NE Ohio year around in temps from 20F up to 100F and the carbs have never been touched. The idle mix screws remain covered. The bike remains stock.
The 02 replaced a 97 GS that was totaled in July 03. I bought the 97 new in Mar 99 and put 80k miles on it in 4 years. Since it was brand new and NE Ohio is the salt capital of the universe I rode an old CM400 as my winter bike and never used the 97 thru the winter. If I had it would have needed rejetting in my opinion, just wouldn't take the throttle below the 40F's without the choke.
So in my opinion the older 89-00 GSs with the 2 circuit carbs needed rejetting for winter use. Mine was quite happy spring, summer, and fall here and in the mountains of upstate NY and on a few annual trips to the Smoky Mtns where it screamed along at 7-9k rpm for hours on end up to 6k feet altitude. Carbs remained untouched on my stock 97 also.
No doubt a low mileage older GS that has sat most of it's life unused might need a good carb cleaning but the 01-02 and later bikes with the newer carbs were good for year around use in this part of the country as long as they are used regularly.
GSJack: I may have asked you this before but I dont remember the answer. Is it humid in summer where you live but dry in winter ?
Or is it dry in summer too ?
Cool.

It's humid here year around Buddha:
Humidity - Cleveland OH
The relative humidity typically ranges from 45% (comfortable) to 92% (very humid) over the course of the year, rarely dropping below 27% (dry) and reaching as high as 100% (very humid).
The air is driest around April 20, at which time the relative humidity drops below 55% (mildly humid) three days out of four; it is most humid around August 20, exceeding 88% (very humid) three days out of four.
Relative Humidity:
The average daily high (blue) and low (brown) relative humidity with percentile bands (inner bands from 25th to 75th percentile, outer bands from 10th to 90th percentile).

the kid I bought it from said the carbs were just done, apparently not. the mixture screw caps were already drilled out but were only about one turn out. ive noticed some other parts missing as well, like some washers and stuff on the carbs.
buddha-I read somewhere to go to 20/132.5/and a 62.5 main, with 1 washer on the needle and about 3 turns, is that right? Let me know when you get them in. I ride all winter as long as the roads are dry and ive read these bikes can be tempermental at lower temps.
Thanks.

GSJack: I dont think I ever asked you this question, cos I've never seen a humidity graph .. .ever. Thorough is your middle name huh.
62.5 mids is unobtanium. Or atleast like Big foot - heard of, but I've never seen.
You dont need it anyway. Just a hair richer is what you need stock.
You jet it to not make more power, you jet it to run cooler and run without hiccups in all weather conditions.
You cant decide if you're running lean by just riding it, you'd at the least need to do a plug pull @ every range of throttle settings, or run with an O2 sensor in the exhaust.
Anyway 20/132.5/3 turns/1 washer is what you would need.
Yea 1 turn on the air screw is asking for trouble. Your float may be high if you even ran with that 1 turn.
Cool.
