suzuki dr 125 tuning for better hill pull on a small trail bike
I am working through suzuki dr 125 tuning on a small trail bike that drops speed on hills. I know it will never become a 250, so I want to remove losses before buying parts.
I found this related page while comparing notes: suzuki dr 125 tuning. I wanted a practical thread before ordering parts.
Would you check valve clearance, carb jets, float height, air filter, plug, intake leaks, chain and sprockets, brake drag, tire pressure and the same hill test before tuning parts?
