Reply To: Bought with a dead battery and still no spark – 2009 GV250 Carby
Coils ?
HT Caps?
Stator Unit?
These 3 need each other. If any of them are out of spec , there lies the “cut outs” you’re experiencing if it is electrical.
Try to get access to a cheap pocket meter and follow this topic:
Confirm back here your findings with the hard figures.
While the bike is apart, clean every single connector plug you can find with Contact Cleaner, incase some gold pins have oxidized due to nature , and ONLY (i mean only) use Dielectric Grease called ACF50 , it is #1 to have in every biker’s tool box. Don’t use anything like WD40 as it’s flameable. Just use ACF50 , after cleaning the pins , this helps the connectors maintain a good connection and not oxidize too soon.
Check for sparks again but this time , see if one coil is better than the other or replace the battery (if too old, the cells discharge too quick, you won’t have a good CCA left for it) , if battery is new , use a bike-charger (car chargers will burn the harness and the battery as there is too much current) , if jump starting = remove the battery out of the car and jump start , if the car / truck is running alive while you’re jump starting = you will quickly say goodbye to the GV250 (again, too much current).
Fortunately a GV250 carb is FARRRRRRR easier to get going than any GTR or GV Injected for that matter. I love working on those bikes when customers drop them off to me.
