Fried the rings in my blaster!!! I have not done any research yet just thought I would ask for some suggestions first so anyone have any suggestions on a cheap top end rebuild kit not looking for any serious upgrades because my 10 year old 8year old and 6 year old kids all ride this bike as well so stock is good enough for now thanks in advance
 
You can get the kits on amazon, but they are a serious gamble. I got two kits before I knew any better. So far I have about 5 hours on each and they are holding up well. I wouldnt care if they just melted down and quit working but the danger is the piston can break apart and the pieces get jammed down in the crankcase and literally destroy the engine. I made 100% sure my engine is sealed up from air leaks and run rich on fuel and rich on oil and check the pistons and cylinder with a camera every hour of run time. So far no streaks or melting. In the mean time ive been rounding up two factory cylinders to rebuild. As far as I can tell, there are no kits that are high quality unless you spend big bucks, you have to bore out a stock cylinder and get a quality piston to fit it.
