^^^^thanks now im not worried bout the front sprocket.:D but what size is the rear stock sprocket? and is 1 front equal to 4 rear?:confused:

stock is 15/38 i believe

The general rule of thumb is that a 1 tooth change on the front is equal to a 3 tooth change on the rear. Of course that's not exact, but it's the general rule that most people go by.

Stock is 15/38 and a little wiggle at the front sprocket is normal.

Actually, I believe it's 1 tooth up or down in the front equals 2.5 on the rear.
