running problems

[98blaster+4]

okay to start off with ,less than an hour before it was running fine and rippin it up.
so as i said i was just riding it, went out with a helmet on to go for a real ride,started it up ,let warm a minute while i was putting gloves on and helmet, rode it aropund the driveway for a lap and headed out ,got about a 50 feet out of the drive and it reved funny( like a plugfouling) and made a pfffffft sound out of the exhaust and dies . changed the plug and fired back up without issue ,idled for a second or two and made the same sound and died.
does anybody have any clues as to whats wrong?
also i was thinking my silencer may be plugged , will a silencer plug up when hot, and run fine when cold

did you replace the plug?. i think if it was pluged up it would have ran funny cold as it would hot ..

yeah i tryed a couple of plugs ,checked the torque on the cylinder, still have compression, getting gas ,and spark, air filter is clean and free of obstructions

but then it quietly backfires and dies

 

[ron89]
