I was riding my blaster in about 3rd gear and then i herd something rubbing in the motor it rode for for a couple of minutes longer then it died i got it to start once then it died and while i was tryin to restart the motor i could hear it rubbin still then i took it back to my house then i idid a compersion test and it was at 90 but i didnt hear that rubbin noise anymore then i took off the head and found a pice of metal in the piston but i was able to take it out and it didnt go through the whole piston i havent taken the jug off but i've look down the jug and pushed the piston and down and goes through the motion smooth so any ideas on wat wrong
 
how does the cylinder walls look from what you can see?. maybe your piston skirt broke off on ya. i would pull the jug and have a look at your piston maybe post up some pics..
 
If your running that low of compression i would rebuild it cause if you run it that low you have a chance ( if havn't already) of breaking the skirts of the piston off. I thought Blaster's ran up around 150
