The 1996 Super 3 that I have does not have the same loop-back wire as on the earlier 900's, the blue wire is a straight connection linked in the tach circuit.. I talked to Hinckleys guy Matt at South Bay and he advised against it. My concern is that my bike lives it's entire life at, or near the rev-limiter. If the engine somehow does not have a rev limiter( like 80's race bikes) you can float a valve and destroy an engine. I have seen it, it is very very bad. You have to replace the head, and if you can save the cylinders, you have to worry about what kind of load the crank experienced when it was breaking the valves off and crunching them up. Older bikes had heavier cranks and I have seen a bent crank on a Honda CB900F. My balls are not that big to risk my motor, so I took Matt's recommendation and dropped the $500+ on the 750 limiter and it worked perfectly- I JUST PLUGGED IT IN! It took me more time to take the seat off. If it works and the bike somehow magically moves the rev-limiter back 2000 rpm, let me know, I need a scientific explanation before I would consider it.
A funny side note, when I worked for Honda in the early 90's I had been a CBR 600 racer, there was a guy selling a little 3x5 template that you taped to the CDI on a Hurricane and then drilled holes with a 1/4 inch drill bit where the holes on the template were. If you hit it just right you eliminated the rev limiter completely. Most idiots destroyed their CDI's and I never saw anyone win a race with one that was drilled. We actually had someone try to submit a warranty claim on one, after that if there were any CDI warranty's we looked at them first to see if they had holes in them.
