I recently, in the last few weeks, aquired two yamahoppers, ones a 80 and another an 85.
I put K&N filters on both, one has boyeseen power reeds but has a bad charge coil (read 200ohms, supposed to be 400, and it wasnt getting a good spark), good news is a replacement is coming today. Also coming today is a zoom zoom 60cc kit and head.
I bought a jet kit 70-110 with two of each in order to jet the bikes right as I go along here.
Any help with an exhaust would be huge and any other recommendations or advice is more than welcome.
