Good day brothers and sisters Just need some advice on my current mods. 1. Cms 62mm racing block. 2. Cms T2 cam. 3. Cms racing spring valve. 4. Tuneboss ECU. 5. Ahm M3 spr Exhaust. Issue is now, i can start my bike normally. But sometimes when i twist my throttle the engine dies (stall). May i know whats wrong with it? Is it the Valve setting or Tappet setting? Please advice. Thank You.
