Hoping someone can help
07 baja wilderness trail 400 with hsun engine. trying to find where the vacuum line in the intake after the carb goes to?
searched the parts lists, servic manual and owners manual. unable to find where its supposed to go
if possible hoping someone can help.

 

I don't know the model at all, but vac lines on bikes usually go to one of three places.
Fuel pump, if the tank is below the carb, a vacuum operated fuel pump is often used to lift fuel to carb.
Fuel tap, a favourite with Suzukis, this opens the fuel tap when a vacuum is applied, so switching fuel supply off as soon as the bike stops.
Breather/exhaust gas re-circulation system. If it has a complex system for either, there is usually a vac line to it.
