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.
