good day everyone. i have a cat eliminator. it has a 68 tooth sprocket on it , to say the least its very worn out. in the OldMiniBikes warehouse there is a sprocket that has the same bore and bolt pattern but it only has 66 teeth. what i need to know is will the lack of two teeth from a 68 to a 66 will it cause me problems when it comes to where the brake caliper pads will ride on a smaller sprocket? the next up is a 70 tooth and its dia is way too big. thanks for any help you can give.
