Question about 1986 Honda VT 500 C Shadow
1986 Honda VT500 starts missing and breaking down at 4k RPM. I replaced two easy plugs, the other two are still in there. I don't know about the other plugs. The bike has 18K miles on it. @
SOURCE: Reduced power below 4000 RPM
The main relay also controls the transmission and will cause an intermittent interruption of power and indicates its going bad. about a $60.00 replacement cost. the relay is located under left side of dash.

Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.

first thing to do is to check fuel level. you mentioned about 290 miles since you owned it but no fillups. did you get gas from same store? not unusual to pickup trash or water in fuel from conv. stores. with that out of the way, look at your plugs and see what they look like. black and sooty would be fuel fouled and very white or very light tan would be lean. if plugs and fuel are eliminated, it could be the result of a stator coil starting to go south. these will require special tools to diagnose.

Testimonial: "Very quick to respond and helpful!"
SOURCE: HOW DO YOU CHANGE THE
There are four spark plugs to change. The spark plug wrench in the motorcycle tool kit will remove and replace the plugs. If the tool kit is missing you can go to the Honda dealer and order just the spark plug wrench (separately off the microfiche tool kit page) necessary to do the job (about $10). The Honda spark plug wrench has a built in grabber to lift the plug out of the deep head access hole.
