The other day I had it running an it was spitting an popping out the exhaust like it didnt want to rev out I shut it off.I went riding last weekend damn bike started ran for 30 seconds an quit.We kicked the crap out of it an it wouldnt fire changed plugs did the same thing.Tonite I took air filter off it started w a backfire thru the carb,sounded like a starter pistol going off did this 2 times an now it wont even fire.I have fuel going thru the carb,when I grounded the coil I had no spark.My 1 friend didnt think it was the coil gone bad.Could bad reeds do this right now Im stumped and having a beer an rethinking the whole thing.At this point if some 1 tells me to set it on fire I just might LOL.
