My son was riding his 2004 blaster was having a blast but ran it for about 4 hours. When he went to ride it home ess than 5 blocks away it stalled and the kick start seized and won't puch down. In addition the bie wouldn't stay in neutral uncle we held down the clutch. He is so upset we just bought it yesterday any help would be greatly apreciated

Sounds like you need a rebuild. Dont use cheap china parts, go online to http://www.amazon.com/Wiseco-PK1089-2-Stroke-Piston-Top-End/dp/B0050FYN4Y/ref=sr_1_sc_2?ie=UTF8&qid=1420937950&sr=8-2-spell&keywords=yamaha+blaster+wise+co And get this. This should be everything you need to rebuild it. Now you need to MIX your oil. Not use the tank. Google blaster oil tank bypass and just remove the tank as it can tear up the engine badly. The oil pump can send shards of plastic into the crank and cause it to fail. Once you have done this, You can have the engine built, mix the oil 32:1 and insert into the gas tank. After this is all complete it should all be running even smoother then before. For any other help go to www.Blasterforum.com

Even if the bike seized, you might still be able to kick it over, and it still be"broken".. you have a oil tank? its needs a quality 2 cycle "INJECTION OIL". if you don't have a oil tank, mix the oil to gas at 28:1... But, you need a major overhaul... If the piston is scarred on the back, and around it, its a lack of oil problem, if it scarred on the exhaust side, its an overheating issue (no oil) will cause overheating. Your professional mechanic will be able to tell you why everything happened!

I would think that the problem is that you have forgotten to put 2 stroke oil in the bike. A 2 stroke needs oil mixed in with the petrol, because it uses the mixture to lubricate the engine internals. It sounds as if you need an engine rebuild. Remove the spark plug and shine a torch in the hole then rock the bike backwards and forwards while it is gear. If the engine isn't dead, the piston will go up and down.
