Do you need a controller?
- Yes, if your bike is stock and running jerky around town... she's lean and needs more fuel.
- Yes, if changing your exhaust from stock and want to get the most from your pipe purchase.
- Yes, if upgrading intake or air filters and want to have your bike run safely and properly.
- No, if you think adding a controller to a good running bone stock bike will make it go faster.
