what is a good size front and rear aftermarket sprocket for a 2003 yamaha blaster

 

How tall are your aftermarket tires. Are they 20 or 22's! Go with one tooth larger on the rear.

 

they are 20 inch rear tires

 

If you want to go faster and lose a little bit of accel get a 14 tooth front sprocket. If you want to keep your accel keep the stock sprockets on. I would suggest getting the 14 tooth though.

 

I was just thinking about changing my sprockets on my blaster also. I have 22" maxxis sur trak's on it though, I ordered a new stock 13 tooth front and was wanting to switch just the back I guess. I don't need the speed, I do more mud riding and hill/trail riding and well am planning to play in the snow this winter. You guys have any suggestions for a back sprocket?
