Chad best thing you can do is one race tech sells a full spring and seals set go for that bike it also uses better oil call them www.racetech.com as for a seventeen front wheel in moto go they all use a 16.5 inch wheel and if the seventeen was better hey would have used it they spend millions testing to get those bikes perfect. Upgrade thwpe front a d rear suspension and if want oleins makes a behind the trees but when I did my suspension and was set up for my weight I took it up to 175 and not one wobble hope this helps
