[bandit400]

i have a 1994 bandit 400 and i changed the engine out and put a 1989 bandit 400 engine back in it, i new all my electics on my engine before were working because it would start and ride, so i change the covers that hold all the elctrics over from the 1994 engine to the 1989 engine i starts puttin everything bk on goes to start it and it turns over but there is no spark at any of the plugs, there is power to the coils just no spark to the plugs, i got told it could be the cdi unit but i got the one off the old engine and tryed that still no spark, i am stuck for ideas, did the 1989 and the 1994 have different coil packs? can anyone help me plz thanks joe
