I bought one of these to try out on my race bike. Unit mounted under seat. My engineer friend made me an adapter plate and I found a bit of ally to mount the pick up on. Rotor comes with the kit. I was going to run twin plugs....might just run a single coil instead. You can use the stock curve that comes with the unit or make your own, its as easy as uploading a photo on the net. With the engine running you can alter the curve, adjust the 'soft' rev limiter, read the actual revs....pretty cool. The curve shown is not the one I am using as I have limited advance to 30 degrees. The instructions are a bit vague, I found as soon as I started the motor the screen would freeze.....this was due to needing 5000 ohms on the plugs.....easy fix was resistor plugs. Raced it all last weekend, ran fine. Would it suit a road bike, yes it would. Would I ever buy another Boyer....no.
