Hi guys,
i have an engine starting problem on my 2006 f4i.
When the engine gets warm above 75-77 c° (170 F°) the sound becoming alittle rough.
If i cut the engine off and try to start it again it won't start.
The starter works very slow like the battery is weak (battery replaced and still the problem remains).
After the engine gets cold it starts no problem.
Anyone had this problem?
thank you for your answers,
Ram.

I understand you replaced you battery but have you checked your charging system ? You need to use a meter to confirm this. It’s not difficult so if you haven’t got one either borrow one or buy a cheap basic one. If your unsure how to do this, a forum member will be here to talk you through it.
A simple oil and filter change might quieten your bike or she might need further servicing if she sounds no better.
Best of luck mate.

 

If you open the throttle some when its hot, does it fire up?
