Does anyone  know how to repair the gauges on these bikes? It's a well know problem. What component goes out in the display to render them useless? Anyone use a universal  one on their bike since the factory ones are so expensive?

I asked a friend. Have to remove the intake tube from the head, not the carb

What is the trick to remove the carburetor  on a 1987 moto4 350?
