Question about Honda VF 750 S Motorcycles
I bought a honda vf 750 1983 off my mate he bought it off some else in bits he put half of it together n then couldn't do anymore. when i had it i had to re-build the carbs as the owner done a service on them and lost all the springs so i had 2 buy 3 sets of carbs to get all the springs i needed, now carbs are on i got it sort of running the other day but the metal plate the carbs bolt on to was back to front. i took it back off n turned it round to fit n now it wont start. its sparking fine and plenty of petrol getting to cylinders. it just keeps turning over.
Initially, pls determine if there is sufficient vacuum on each cylinder. Remove air cleaner, housing and expose the carbs. Crank the engine while trying to cover the carb opening with the palm of your hand. If there is vacuum, then your palm would be wet with fuel. If there is little or none at all, then there is a leak between the carbs and the intake manifold.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
