Need Help

[bklf7]

I bought a banshee off a guy and ended up rebuilding the top end. I am finally getting around to getting the whole bike back together and am having a problem getting it to run. First I had to splice the wires for the cdi individually, but the wiring harness has more wires than cdi has but I am getting what I think is a week spark but not sure. I have no tors or e-brake switches on the bike. When I try to start it the bike pops but definatley doesnt sound like it wants to run. Also when I am trying to start it fuel runs out of the overflow lines at the bottom of each carb. I have an extra cdi I can wire in but has the same amout of wires on it which if I remember correctly the extra wires that are not connected are a yellow and a green wire. I really need help here. I also tried pouring gas down the cylinders and the bike does the same thing.

Your fuel problem is the needle and seat in the carbs, a carb overhaul will fix that, if the bike has sat up for a while a good carb clean would prob. be neccesary anyway. As far as your firing problem, you need to check your spark for sure and see whats going on, see if you have spark or not, then if you have spark see if it is weak. you should see a good blue spark. Why did you have to splice the wires, were they cut or something, I would also check your connections on the splice, ecspecialy if you used butt connectors, sometimes those things dont make a good connection like they should. Make sure all ground wires are in place also, a bad ground will cause some crazy shit. If you need a wiring digram they have them posted all over this site, just check. I would also check your connections on your stator make sure everything is plugged in and work from there. Post what you do and what happens when you do it and you'll get the help you need on here!

Another thing I just found was that I just did a top end rebuild but when I checked my compression with my thumb over the hole it doesnt seem to have hardly any comp at all. I cant think of anything that I might have done wrong when I put it all back together. All the splices where just twisted together for now until I get this thing running. I guess I will try another coil to see if that helps my weak spark (atleast I think its weak). Any other suggestions would really be appreciated. Thanks

OK you'll need to get a compression gauge (invest in a good one if you don't have one) and see exactly what your compression is, we need to remove any doubt about that first. then we'll go from there. Keep in mind you need fuel, fire, and compression for the engine to run. Also the wires twisted together, not gonna work, fix that right dont leave any loose ends that will cause you big headaches later. That could mess up a good day of riding or in your case getting it running!

Well your ground comment got me thinking. I remember reading about the red with a black strip wire being a ground also so I grounded that wire under the volt regulator just to make sure it had a good ground and BINGO it fired right up. So I guess I will button everything up and take it for a spin. Thanks for all your help I really appreciate it.
