riding when its hot

[wmh9680]

Good morning, I've noticed that when it is very hot out (heat index over 100) and we stop briefly when I go to start it it needs to crank for a bit to start, is this normal. Once it starts it's fine. Very hot here in ChiTown and we will be ridin again today. Thanks, Mike

It's a function of the fuel injection system.
Hotter air is less dense, so it requires less fuel for the proper mixture...

But less fuel; means tougher starting! :banghead:

When you stop, so does the radiator air flow.

Everything inside the body work gets "heat soaked" and that includes the intake air for a few strokes.
Less fuel plus hotter intake air equals a tendency not to fire off right away.

BUT.....this also can be a sign of a battery getting weak.
If yours is the original, you might want to get it tested.......or replaced.
