- Replace or clean the fuel tap under the tank.
- Open the FUEL pump that is on the frame and use carb cleaner to clean gently

- Do the “Slide Mod” tutorial (recommended)
- Get the carbs involved in an ultrasonic cleaning process, it really really pays off.
Fuel = Try to use E5 grade fuel. if you have fuel that is E10 grade, you will have problems because there is nothing positive about using E10 grade fuel that some pumps wan’t to introduce , your country may have it under a different name but we call it E5 and E10 here in UK.
