The alternative is to put a smaller sprocket on the back on the wheel. Engine sprockets are usually less expensive because they're smaller. You need to calculate the final drive ratio, this is the number of teeth on the rear sprocket divided by the number of teeth on the front sprocket. Ratio =(back/front) To find out what will happen by adding teeth to the front change the number in your calculation. You don't want to change/lower your final drive ratio by more than about 0.5 with the small engine you have or it won't climb hills vary well. You can do the same calculation by changing the number of teeth on the rear sprocket. Example Stock Sprockets Front 13 Back 46 Ratio=(46/13)= 3.54 Bigger Front Sprocket 14 Ratio=(46/14)= 3.28 I hope this helps. roost66 is half right, you need a bigger sprocket, on the FRONT on the engine not the back.

Example

Bigger Front Sprocket 14 Ratio=(46/14)= 3.28

I hope this helps.
