Well I took a 20 mile ride today. Just Awesome! I switched to opti-2 that i have been reading about, and it is running great! The back wheel sprochet is slightly off center so she's a little chuggy at low speed, but at mid to full throttle runs really good so i hesitate to change it again. At times it 4 strokes but I guess it has to break in first before I mess with the carb. It's the blue filter, I think it's called cns v3?? Dosen't sound like theres a whole lot I can do with them anyway. WELL MANY THANKS TO EVERYONE WHO HAS BEEN HELPING ME!!
