Few years ago we bought a little bandit for my wife. It was quite badly keeped so it was a cheap buy. Cheap indeed, airbox cover was missing, every bearing was fucked and there was very badly made "modifications" here and there.
Started to overhaul it last year and did the worst faults first. One very odd and annoying is still there. It is very hard to start when the engine is cold.
Done so far:
New plugs
New coils
Ultrasonic clean for the carbs
New seals and misc parts for the carbs
Relay mod for the coils
Stock setup for the carbs
Fuel tap checked
Compression tested the cylinders
Valve clearances
Spark is very strong and plugs are wet after cranking. It starts if I jump start it and after it is warm it starts right away. Any ideas what to check next?
