@rulookin: AS Mv continues its model range, the phrase "my F4" loses more and more meaning.

We implore people to put their bike's year and model in their signature line...or at least in the inquiring post...so that teh correct information can be referenced.

Help us help you!

You can download the manuals for free from Donsy's site, it's in a sticky at the top of the page

Has the starting issue got worse since the bike was serviced or has cold starting always been poor? It might be worth checking the earth connection and the connection to the starter. If you have just replaced the battery presumably those connections are fine.

Does the bike have the latest ECU map loaded? It was released in service bulletin 166 issued in December 2015. That upgrade did include some changes to the starting sequence which improved starting on my F4RR. The map version for USA/Canada is 0515FF38. (My bike is a euro version so has a different map).

Have you tested the air temp sensor and found it is out of spec?
