Honda VF 750 1983 wont start

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.

Hi,

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.

I own a 1984 Honda Magna VF 700. The speedometer broke and the part is discontinued. Is there another part that I can replace it with? Looking for something in stock to use and not concerned about original parts - just something that will work.

Well, when you take off the fork make sure you empty it first before anything else then make sure that the fork pressure spring is released before changing the seals. The fork oil amount should be no more than 200 cc or no less than 190 cc

My honda vf 400 f is idlind very high and than after i put it in the first gear closing the clutch a bit than only does the bike idle normal. is this a normal clutch problem or something else?


well the idle drops because the clutch is slipping making the engine work harder at idle so adjust the clutch on the lever and to drop the idle on carbs there will be a screw this is the idle screw turn this out until it idles at 1000rpm buddy get back to me if no difference 8910b55.jpg

My honda vf 1100 honda wont start after riding,is there a charging problem ? Thanks


Chances are, YES.

Simple chraging system test:
Start motorcycle
Turn HIGH BEAM light ON
Run 10 minutes or until warmed up good
Rev the RPMs to at least 3,000
Remove the positive battery cable

If the motorcycle dies, then there IS a charging sytem failure.
If the motorcycle continues to run, have the battery checked at a local parts store. If they do not know the Cold Cranking amps tell them 235.

If it is a charging system failure, send another question and I can walk you through diagnoses and repair.

Hoda vf 750 wont start


hello and welcome
with that long of a storage period it is a safe bet that the jets in the carbs have plugged over. this can happen with little as a month or two without proper winterization or fuel conditioning prior to storage. so the carbs will need to be removed and cleaned properly. this is quite the task on the older v4 hondas. and i would reccomend a manual before doing so. after being removed a good can or two of aresol carb cleaner and a small gauge wire to break up builup can clean these carbs out. this is a very very common problem. and im sure you will find this to be the source for your no start. thank you.
