Top speed problems
Hello, i have a 1992 vn750a model, i own it for 3 years now and i fixed some problems on it already but i need some opinion to solve this one im posting.
recently i noticed that my top speed lowered i could reach top speed before and now not anymore, so when i push the trottle she goes fine but when it reaches arround 4000 rpm it starts to struggle to accelerate more, it never did this before and now it's constant i can only reach now 120km/h wich is arround 60 mph if im not misstaken, it feals like it looses compression on one of the cylinders. The stator, rectifier, battery are new. i can start the bike easy cold or hot, spark plugs are new also. another point, when warming the bike some times i get white smoke.
Any solutions or sugestions please reply
