Default Re: Making a custom bike engine

Thought out the crankshaft and timing today, the shaft will be made from multiple parts that are press together, ie: shaft segments, crank disks, and crank pins. I will make the parts a tight press fit and will cross pin the parts together with 1/4 inch pins. For the timing I am thinking of using a "wasted spark ignition." This ignition system is well suited to boxer type engines. This system is a distributerless ignition system using a double ended coil firing both Sparta plugs on each revolution, that is, on both the compression stroke and the exhaust stroke. This system only requires a single contact breaker and single coil to run the cylinders. Another advantage of this design is that it cuts the number of parts needed in half.
What are your guys ideas?
