Starting problem on 02 954 with a pcIII usb
My roomate has a 02 954rr it was a non california emissions bike when he bought it used. The original motor blew 2 plugs out of the head, so he just bought a used motor out of a 03 california 954 the guy he got the motor from put in the motor, throttle bodies and the ECU out of the CA 954. He just took the O2 sensor out and didnt connect the O2 connector to the harness. He got it running good it would idle and run fine. It would just pop out the exhaust when you let off the throttle from high rpm. So he figgured he needed it remapped so he took it to a small bike shop in the area and they put a pcIII usb and said they maped it. Now the bike will not start unless you hold the throttle open 1/4 of the way then if you let off the throttle it will die. But if you hold it at 4k rpm for about 20-30 sec and slowly come down it will idle. So i looked @ dynojet webpage and they said you need the O2 eliminator. Well i hooked his PCIII to my computer and looked at his map and it was identical to the Dynojet Yoshi map they have for 954.. and the guy charged him $150$ to map it and it doesnt even idle... Any ideas
