Bought this bike in January! 2300$ from powersportsmax. Shipping took about a week to get to Illinois. It arrived pretty much in great shape other then the rear fender decal was peeling off but I just figured the stripe knew it was a gonner anyway! I've changed oil to 10w40 wet clutch motorcycle oil and replaced the weird spark plug with NGK! My carburetor came with a 98 main which I switchedIMG_20170523_172934.jpg out for a 107m. Not sure on pilot jet size because its not stamped so I haven't messed with it! I have put almost 500 miles on it over the summer! Maybe u guys can clear up my anxiety on a few things as this is my first true motorcycle! 1. Chain is damn tight still after 500 miles with no room for adjustment to give a c*** hair more slack! Maybe I'm just not patient enough to wait for it to stretch or should it have stretched a little after 500 miles? (2.) Rear wheel makes a clanking noise when rear wheel is spun by hand! Don't really notice any noise while riding or I just can't hear it over the exhaust! Could it just be the chain making noise while rotating around the sproket or should I look into wheel bearings? 3.) Gas cap is constantly leaking and does not screw in completely to make a tight seal!
