So this weekend went riding with the kids. Rode for half a day perfect no problems. Everything was going just fine. Stopped cut it off walked around. 5-10 min. Went to crank back up. Button clicks. Try again nothing. Try to kick it it kicks but feels hard and sounds like I'm not sure but the closest thing I can think of is pushing my son in his power wheels. Gonna break it down and check it all out this weekend. But wanted to throw this out there. Maybe giving me ideas of what it might be if anyone has a clue. Thanks

Welcome to the site !! \:D/

You might want to check the de-compressor on the cam i would guess if its hard to kick then that is what is raising the compression making it hard to kick over , which would also make it hard for the E-Start to turn the engine over as well

While your checking things , check your valve clearance as well , since you have the valve cover off , but i would think your starting issue is in the de-compressor malfunctioning or a broken de-compressor spring or pin

This is not the reliable bike I thought it would be either. Never wants to idle right. spent hundreds on it since I got it. One day is awesome the next day is as jerky as can be with a touch of the throttle. I was thinking reliable low end power but very confused.

From the factory they run horrible ! Jetting is so lean the poor things can barely stay running and run hotter than hell. Jetted properly they are a 100% different bike ! =DD

Yep ! , the bikes are sold to pass Emissions , not give you pleasure (according to the EPA) so you have to De-emission them so to speak , and make them work for your altitude , etc , basically the bikes are choked up and you need to make them breath
