engine tuning for a moto guzzi v85tt without losing touring manners

engine tuning for a moto guzzi v85tt forum question

I am curious about engine tuning for a moto guzzi v85tt because the bike has character, but I would like cleaner low-rpm response and a little stronger roll-on without ruining touring reliability.

I found this related page while comparing notes: engine tuning for a moto guzzi v85tt. I wanted a practical thread before guessing.

Would you check valve clearance, throttle body balance, air filter, plug color, exhaust leaks, software updates, fuel trims, clutch feel, gearing, engine temperature, warranty and fuel range first?
