I have another problem with my aerox, not sure why this is happened but i went to start my bike about 2 hours after i did an hour long ride and it was kicking over fine but then the engine just siezed, i thought i'd leave it see if it got better but it didnt. the next day i wound the crank backwards and the engine had compression was moving freely, but after a few turns forward it makes a horrible squeeking noise? what could this be? i've taken the exhaust off looked in the exhaust port and the piston rings are fine but there are a few sorta like scrape marks, there not scores but look like the pistons been rubbing on the barrel? i think it could be the piston getting stuck in the barrel? Does anyone have any idea? any idea how to fix this? and does anyone think the barrel has been damaged? Cheers
