newbe with ignition question

Hello all
Last week I lost the key to my 2000 foreman 400 in the woods. I found out that if i cut off the ignition wires that I could hot wire it….so i proceeded to cut off the ignition switch. there are 4 wires, red, black, red w/black stripe, pink. I tied together the red and black and i could start the engine with the starter. Got home and re-spliced wires back together with switch and used my backup key but the starter will not turn over. but when I use the pull start, it will fire up. Not sure what the problem is…any ideas???
