Cold Cranking Got You Down?

Cold cranking slowing you down?

A recent phone call from a client reminded me of some good information to pass on to Hayabusa owners. About 5 or 6 years ago I built a Gen 1 engine for him. He called to say he really loved the engine and that it was still performing very well.

When his old battery died, he decided to buy a new Lithium battery. He was amazed by the starting power the new battery has. He said if the Lithium battery had been available years ago, he would have gone for the higher compression engine.

Some of the Lithium batteries on the market today that fit in the stock Hayabusa battery location have double, and triple, the cold cranking amps of the stock battery.

In this case, knowledge really is power.
