Hi I have a 96 blaster just got it about a week or 2 ago and was out riding and all the sudden the back wheels locked up and won't turn so I pulled off the chain and the wheels rolled but the front sprocket turns about 7 times then will lock up and I have no clue what this could be!!! But when I get it to roll again all gears work fine but than same thing happens again over and over about every 5 mins any help would he greatly appreciated. Thanx
