slow starting

[kparkfan]

Today I was on my way back from my moms house I stopped to get some gas. When I went to start my bike it acted like the battery was going dead and then vroom it fired right up. Is my starter getting to hot or my battery getting to hot. DOesnt do it when the bike is cold only when I've been riding for long periods of time. And it just started this today.

Check your spark plugs and see if you're running lean.

Hi,

Bring a meter with you and check some voltages after a long ride.

I have had bikes that start just when you let off of the button.

too hi of amp draw from bad starter motor or battery is not holding the load it should.

A hot starter be it from the engine or overuse will present problems at temperature and work fine when cold..

the test is to see if the starter is pulling over 70amps when engaged

normal is like 35~55 and if the battery voltage drops below 10DCV no spark will happen.

Another thing that will cause that on a hot day after a hot ride will be if one or more of your carbs leaks past the float valve seat and causes a partial hydraulic lock on the engine (I've had it happen). I crack the throttle a little then and it cranks up normally and starts. Might check that too.

my 850 has the same problem.. i have no idea what causes it

1 thing i do know is when it sounds like its a flat battery if i pull all the HT leads off the plugs it spins over fine

Check your grounds too.
