blaster wont idle

Well start off by going over the bike with common problem spots and use proccess of elimination. Start by putting new gas in it. Try firing it up from there. If that doesn't work, change the plug and check for spark. If you can, check the compression. It should be around a healthy 120 PSI. If it isn't firing after that, post and tell us what happens. Hope the info helps. =]
 
What does it do when you do get it running? Does it have tors on it still ? does it have leaks exhaust/engine ? Have you cleaned out the carb yet? Is it getting gas? Change your air filter lately?
