Rejetting Q, Kit or poor man guide?

Well I've kind of dug through the forums for a few hours now, so I figure its appropriate to ask. I think I have a pretty good idea of the process involved at this point (replace a smaller hole with a bigger one, and find an air/fuel balance so it runs well) but..

I want to add K&N pod air filters (get rid of the airbox), and maybe a new pipe, which I don't have a problem doing alone, but apparently I need to rejet to do that, so the question is:

Which is better, a kit, or the poor man's guide (http://www.angelfire.com/mt2/mikesgs500/rejetting), or are they essentially same when it comes down to it, with one just being cheaper? I cant really find a pdf or anything of the directions that come with the factorypro kit so I cant really determine which is easier. Looking at the somewhat vague (to me anyway) 5 step instructions on dynojets site I would be better off with the poor man's guide just because the instructions are step by step and easy to follow (it said somewhere 3-4 hours for a newbie, but knowing me it'll probably be a good weekend at least..).

Being a newbie, and assuming I should even try, should I go with a factorypro kit or poor man's guide? Am I better off with support provided by factorypro..?

I want to give it a go, for the learning experience alone, but obviously I'm a little antsy about it, just because if I screw it up somehow and couldn't get back to where I started.. If I screw it up will it cost $500 or less to fix it?

i did all mine myself its not very hard. it took me about 1-2 hrs to do it the first time and i dont normally work on bikes that much. i have 150 mains 40 pilot with 1 washer under the needle with moded stock exhaust and with some after market pods not k&n but they work(better than that dam air box). do not get the dyno jets, the reason is i got them and the are a real pain to figure out, i had alot of isusses with em, their biggest size is only 125 with isnt much at all. i got my jets from a local suzuki dealer, but if buhdda reads this forum you can get some off him he sells them for a good deal.. good luck with every thing.

A buddha jet pack will have some magic powder in it to get it fixed up.

OK just kidding. But you need that same 150/40 combo with pipe and K&N that dreamer_85 is using.

DJ crap is literally in comprehensible and illogical, its like speaking in tounges.
Factory is good but sorta over $$ and its in a way unneccesary.

Stock needles with washers work well, so do mikuni mains and pilots. The DJ and factory dont have pilots. Which is OK for 99% of all bikes, but on a GS it does not work. +1 on pilots ... else it will be lean at low rpm. Nothign you can do will fix that.

Anyway Buddha kit = 22 shipped in lower 48.
Buddha Jet job = 45+ return shipping of your carbs. You get cool pics of your carbs and whatever when I am fixing it. Drilling of jets or screws or whatever extra. Other broken stuff extra. Ask the over 1 satisfied customer ... what - he's not satisfied any more. Crap ...

Cool.

I actually have a >'01, so its 22,65,150? And just to clarify, adding washer/adjusting the needle is to increase fuel flow mid range, right ? IE more washers more fuel flow between idle and full throttle ..?

I'm kind of confused on the needle jet, I think I get it I'm just not entirely sure. That and what is the mid jet for..? I haven't seen any examples of carbs with three jets.. I imagine by the name its mid range also. I guess I should just go find my clymers to look it up.

Edit: Like in this pic (http://justkdx.dirtrider.net/images/Smaller_PWK_highlow_speed_animation.gif), why even have the main jet there? Why not just have a needle with a different taper?

I'm pretty sure changing the mid jet gives similar results as washers under the needle but with a higher price  :confused:
Not 100% sure though.

I'm pretty sure he's right.
