No clip on needle, must use rings to lift needles. or install dynojet kit.
BUT: in my very own personal opinion, after tuning efforts for more than 
one year my simple statement is: leave it as it is. 
the negativ effects outperform the positiv ones by far. As said already: 
simple modification of the airbox + using a K&N filter did show no effects 
on a dynometer test compared to original setting. Just additional 
consumption of 1 liter fuel...
Installing dynojet kit, changing muffler and manymany runs on dynometer 
brought some more hp. The price ?  about 2 liters more per 100km....plus no 
performance over 1.500hm...plus no performance below 5 degrees...plus a 
completly stuck airfilter because of some offroad (where the orig. filter 
would not moan about)...plus a dying engine after a highspeed watercrossing 
because water in the air filter through the additional air holes...plus a 
muffler where you must avoid fullthrottle inside the city, or all windows 
will break within 100m and subsequent 20 police car behind you...not fine.

On the good side was a funny experience on a closed formular one course, my 
AT had higher end speed, so it was easy to reach and defend the inofficial 
first place (was labeled bike test, not race :-)).
