Working on a new old bike
the bike starts and runs pretty good when it's cold
after 15 or 20 minutes shut it down and try to restart
it will not fire up leave it set a half hour or so it will fire and run good
I was thinking possibly a bad pickup coil? Or ignition coils?
Appreciate any information gary.
Common problem with the vn750. I saw your earlier post about having the carbs cleaned, and the choke not working. Have you resolved that problem yet?
Check the link in my sig line and especially note info about a MF-AGM battery, NGK IRIDIUM PLUGS, Part # DPR7EIX-9, Seafoam fuel condioner and the phantom out of gas syndrome (poogs
). Also check fergy`s sig line for a link to regapping the ignition pick-up coils, and running a direct 12 volt line from the battery to the igniter terminals for a hotter spark.
I believe that we have recently concurred that the poogs
is usually caused by a plugged vent or vent line. Remove seat and note black rubber hose attached to nipple on rear of tank. Follow hose down in front of rear tire, and put a piece of white paper towel under it. Open gas cap and note small vent between screws on hinge.
Spray some wd-40 through red straw into vent, and watch for crud flushing from bottom of hose onto paper towel. If it is a lot of black crud, the vent or hose was probably plugged. Alternately, use compressed air to blow line clear, if you have it.
If the vent is working properly you will hear a high pitched whistling noise as air enters the tank, replacing the fuel volume consumed after riding several miles.
