Hard to start

[Akins]

My 08 cbr 1000rr gives a lot of trouble to cold start. I changed the spark plugs and put new ones. A guy told me it was the injectors that needed cleaning. I used for redline fuel injector cleaner still no change. The strange thing is that if I jump start from a car battery or I push start the bike starts immediately. Anyone have any advice on how could I solve this issue.

Weak or bad battery is a possibility

New battery

What brand would you'll recommend cause I have a new one that never performed properly. I would also check the voltage on the present one. Thanks guys

Just to confirm the battery condition take it and have it load tested.

If you want to check the voltage put a meter on the battery and record what you get with the bike not running, this is your battery voltage.
The battery voltage should be between 13 - 13.2V for a fully charged battery, less than 12.4V then the battery needs charging.

Then start the bike and recheck you should see an increase in voltage, this is your charging voltage which should be
greater than your battery voltage but less than 15.5V when checked @5000 RPM
If you do not see an increase in voltage with the bike running further troubleshooting of the charging system will be necessary.
