I have a 1986 VFR 750 with a strange kill switch issue. When the bike is either off and I try to start it with the kill switch turned to off or running and turn the kill switch to off, the kill switch will seemingly do it's job by killing the engine. Yet when I try to turn the kill switch back to the on position, it will not start again. The engine will crank and crank but never turn over. Now comes the strange part. If I wait at least a day with the bike turned off and then try to come back and start it later, it starts up as if nothing is wrong. Thanks vfrworld.
You could have some dirty or corroded contacts on the switch. Suggest testing the switch by unpluging the coupler under the fusebox and using an ohm meter to test continuity (in RUN position) between black and back/white wires on the handlebar side of the connection. Getting spark at plugs will not happen if that switch is not making good contact, so no start and a quick way to determine spark or fuel. A common cause of a bike not starting one day but doing OK the next is possible over-use of the choke, causing fuel-flooded plugs that dry off after a few hours. Don't slam on full choke for starting; use about 1/2 to 2/3 at first and only advance lever if you need to. Also, i prefer to use the idle adjustment screw to get a fast-idle warmup rather than use excess choke, but this has been a previous item of debate.
Thanks for the input. Sounds simple enough, I'll check it out this weekend. It's a fairly uncommon occurrence, but I've been stuck twice now for accidentally hitting that kill switch while the bike is on and not being able to get it started again. I'm fairly certain it isn't connected to the amount of choke I've given it, but thanks for the heads up. I was so unsure about this one- I thought it was some bizarre anti-theft device.
Later gen right side switch gear is a direct replacement with a much improved design. I have a gen 5 on mine.
