Mine is doing the same thing. Would also like to know.
the 690 doesn't like low voltage batteries on their way out either. it looks/sounds like its engine management is fighting somethingHi everyone, im currently having some issues with my 690 when starting it up.
No matter if the engine is hot or cold, it takes 3-4 attempts on the starter to fire it up.
Decompression spring has been switched a couple of years back and according to previous owner everything was fine for awhile after that.
It has never stalled or anything once its up and going, however its abit jerky and groggy on the lower end of rpm's.
fuel filter/injector issues?
heres a vid of a startup:
No im not doing anything besides starting it up in the video.Pretty low RPM when it does fire. Are you giving it throttle to bring the RPM up to 2k or is the computer doing that. Add some throttle body checks to your list - specifically whatever minimum air is called for this bike. I have a vortex so my idle speed is manual adjust, your bike sounds like mine when I try to start it without bumping up the idle sometimes though that is definately heat - dependant.
I have the same issue, in the morning it start perfect. After the working day I need 3 or 4 attemps. Did you solve the issue?So basically if i let the bike stay still for more then 1 day, it always starts up on the first attempt.
However if the bike's already been ridden within the same day or just a few hours between it's back to 3-5 attempts to start it up.
