Question about 1988 kawasaki VN 750 Vulcan
Engine starts up but cuts out wen accelerating. Also trying to find exhaust pipes with silencers for my 1984 model + price. Many thnx, John
1. Remove the airfilter box and try to rev. it up but dont yank it up rev it up in a 3sec time interval from 0-9000rpm. If it revs up replace your airfilter it might look ok but the material it is made of ages and with damp in the air closes up the micro holes in it and chokes the engine as soon as you rev it up. If you have an airbox don't fit those smaller individiual airfilters you would have to get it jet dynoed, what I am saying is fit the same type air filter back on or you will have fuel air problems.
2. Remove the exhaust manifold from the head, start it up and rev it up in a time interval of 3sec from 0-9000rpm. If it revs up your exhaust is blocked and you either have a wasp stuck in your exhaust outlet or it is aged and blocked. Try closing your mouth and nose with your hands and breath in or out, this is the same with your engine.
3. If this does not rectify your problem you will have to look at your carburator float levels or your coil packs. Let me know if it work or don't so that we could fault find your problem this is the easiest and the firts steps to follow.
