do u got put news sprockets on when u get new rimes an tires for a 2003 blaster

 

that depends on the size of the the tires. If you got rid of those darn balloon tires and upgraded to a smaller, nicer tire, then you may want to go up a tooth in the front, depending on how much smaller the tires are. If they are only a little smaller, you could change the rear sprocket 1 or 2 teeth.

 

iam gettin razor 20x9 on the back what size sprocter should i get.or 20x8

 

If you leave the sprockets stock with the new tires, you will notice a good improvement in accelleration. You may lose a little bit of top speed, though. So it all depends on what type of riding you do. If you ride MX or woods or tight trails, I would leave it stock for the better accelleration. If you ride desert, dunes, or wide-open areas where you want top speed, I would go up one tooth in the front sprocket.

Either way, your most noticeable difference will be in handling. You will get alot better traction all around. Have fun!
