honda sh 125 tuning for city pull without killing reliability
I am helping with honda sh 125 tuning on a daily scooter that feels soft from lights and slower than it used to be. Before tuning parts, I want to know if the CVT is tired.
I found this related page while comparing options: honda sh 125 tuning. I wanted a practical discussion before ordering anything.
Would you inspect belt width, rollers, variator ramps, clutch shoes, air filter, plug, brake drag, tire pressure, battery voltage and the same route before changing parts?
