I bought a 2006 with 688 miles on it. Looks like new. Only thing is he let it sit for a couple of month's so it doesn't idle and choke is erratic. Runs great once I get it above 25-30 miles an hour. I just want to bump the pilot jets up to a # 20. I have removed the air box and am getting ready to take the carbs out. I don't really wnat to disconect the throttle cables ( did the choke ).
Think I can just pull the carbs leaving the throttle cables on and drop the bowls and clean all the jets except for the replacment of the pilots to # 20? Just trying to make things easy or do you think it wont be good enough? I'm thinking it's primarily clogged pilot jets.
Thanks for any feedback :D
I think you should be all right. The start up will be easier too after rejet.
Why are you trying to avoid touching throttle cables?? They don't bite ;)
cheers,

I'd be adding a bottle of carb cleaner to the best premium unleaded fuel you can get and be taking it for a thrash to clean those carbs.
Is the bike stock or have the exhaust/filter been changed? If it's been sitting a while and just not acting weird, you might just want to try pulling the jets out, soaking them in carb cleaner and scrubbing them a bit, and putting them back in. I know the bike is jetted lean from the factory, but it shouldn't be that bad. I would think cleaning them might be enough for you.

actually this is NOT the case here! his bike is 2006 which means that he has 17.5/65/130 jetting which is much better than older GSes had.
the f models will run ~13:1 afr stock, which is not too lean but a little extra fuel would give some driveability and make warm ups faster. a good tune for a stock f model would be stock jets with 1 washer under the needle and a few turns out on the idle mixture screw. my advice is to clean the stock jets, then uncover the mix screws and open them up to 2-3 turns out then put 1 washer under the slide needles (1 per carb). and while your in there prolly stripping every screw on the carbs replace every screw with stainless allen screws. It only cost me $8 for all 14 screws and 2 washers plus it made future disassemblies very easy.
Getting them out is 99% of the work.
Pilots jets and washers and air screws are just minutes ... I'd do +1 all around.
Anyway I sell it all in a pack for 25 including bolts for the float bowls.
Cool.
Buddha.
Mmmm, maybe I'll just clean the stock jets and back out the air/fuel screw 2.5 turns and see how she goes.
Should I check out the valve clearence now that I have the tank off ? It's got 688 miles and I see matinence check for this at 600 miles.
Thanks for all the feedback! I just bought this used and have a lot of questions.
I wouldn't worry about valves for the first 4,000 miles.
I would check the valves if you haven't done it yet.
I think that the first 600 mile maintenance (after break in) is quite important. If everything is within spec then don't worry about valves until you reach 4000.
Merry Christmas to you all!
