I have just changed the battery in my honda cbr1000rr after one month and it not firing up?

It a honda cbr1000rr 2008 model. The bike's battery has been dead for more then a month… And it was parked in the sun for two months. The battery is good now but the bike won't start. It just keeps trying but it doesn't.

Take it for a service.

I would check and or replace the gas - Letting it sit in the sun can start the drying up of it. Try putting in fresh gas. Maybe even a little fuel refreshner.
