I got some 400 miles trips with ag50, so my advices are-
-don t use free flow air filters. Use your stock air filter and crankcase breather cos it s a part of engine overheating protection.
-change engine and final reduction oil with high quality fully synthetic
-take basic tool kit you got with your scoot + a piece of sandpaper, spare spark plug, classic grip pliers, a can of engine oil, adjustable wrench and tire repair kit.
Generaly, I advise not to use wot for long period. You will get to the point where you got top speed no matter you twist full throttle or 3/4. You will feel when engin is gonna start to loose power as it gets warm, so take a break for red bull or coffee and let your machine to cool down for at least 15 mins.
Also, I advise you to use kindey belt because it helps a lot. Without the belt , cos of helmet weight, I got neck pain very quickly.
safe ride and good luck
