I am working on a buddies' 1997 shee. It is all stock and he has had trouble starting it. I could not start it at all, so I checked for spark and there wasn't any. Going through the steps in the manual I concluded that it needed a coil. I replaced the coil with a new one, and it has spark now, but it is very weak! My briggs and scrapiron lawn mower has way more spark than this.
I cleaned the carbs and found the bowls swapped so obviously the choke was not working. It has stock jetting, but it is stock for now so it should be OK. It is very random as to when it will start. Some times it will start with a few kicks, other times you can kick it until you cant feel anything from the hip down and it will not start.
When it is running it feels pretty good. This is the first Banshee I have ridden so I have a limited frame of reference. I own a 2004 CR250 so I am not at a complete loss on judging acceleration.
If you stall it or simply switch it off, thats it, party is over, it will not start again. I tried WOT to clear flood, turning on choke for more fuel, to no avail.
What I have done so far:
New plugs
New coil
Copression 124psi 122psi (hot & cold, w/snapon gauge)
Cleaned carbs, swapped bowls
Checked stator coils (I know they still could be bad)
My next thought is to change the stator. ::
