Difficult cold starting

I had a new Hayabusa that only got used once of twice every 2 weeks and the battery craped out in 18 months.

Replace the battery before it stuffs something else more expensive.

Most batteries are only good for 12-18 months these days. If you can afford to, get a top shelf unit with a better amphour rating. Its what you need for cold weather starting, and should give you a better battery life span as well.

No power in the garage? Not saying this would work, but you could consider;
