I am going through the same issue myself actually, but I am curious as a new rider, how much your prepaid maintence plan was? How long is it for? Would like to compare with what my dealerhsip here in HI is asking
Absolutely.Save the money and buy some tools and a Service Manual. You'll be way ahead in the long run.
The better you know every inch of your bike, the more enjoyable and safer it is to ride. After the warranty you will save money.
You can often stop problems before they occur.
