This bike allready from the factory is very lean and runs very hot.
I would recogmend a basline of a 170 main 48 pilot slight adjustment on fuel screw.
Recogmend an adjustable needle either stock ys or shim the factory needle.
The JD jet kit works fine also, plus there is alot of data on this web.
Ride the bike and see how it feels at the different throttle settings.
Either boggy or sputtery and adjust as necessary.
Thumper faqs is a very good source of knowledge.
trial and error will get the best setting.

Check for the breather hose mod if you are worried about water
The '05 already has the breather hose vented to the airbox. Cutting the grey wire doesn't produce a monstrous, uncontrollable hit. It only changes the ignition timing a bit, allowing the bike to efficiently use all of the extra gas the throttle stop mod creates. Furthermore, if that is your intended end result, then you're likely going to need a bit more carb tweaking once you do pull it...SC
