welcome to the world of the VTRSP1 or RC51 as its known in your neck of the woods. The PC3 is always a good investment for this model as it smoothes out the torque curve from bottom to top, especially on this model of honda. Lift up the tank and rip out the filters and use a dremel to cut away the mesh from around both of them and then replace them. There is a website to go to that can help you alot,
