So last weekend,Saturday I went to my garage to take my bike out for a ride. I tried to start it but would not start as if battery was almost dead.so hooked up my charger for quick start and bike was still having a hard time starting,but finally started.had to hold throttle for about 5 min. then finally the bike idled ,for my ride the idle was low Following day take it out again starts rite up no problem ,rode bike for about 30 miles went wide open throttle at stop light ( being stupid) and it shut off, started rite back up no problem .started it today and was long start,let it warm up it just took it up the street and lights start dimming and about half a mile down the road was slowing down and felt like it wanted to stall so turned around and as soon as I pulled into drive way stalled out, but starts rite back up.could this be because of the cold? Or signs of needing a tune up? Any input is helpful thanks

 

the first things i would check would be the charging/battery voltage and the fuel pump.
did you hear the fuel pump while it was cranking and not starting? fuel injection components need good voltage to operate properly.

 

i hear the fuel every time i hit the cut off switch on .the funny thing was to that friday night i had a friend over and was showing him the bike and it started right up no problem.

 

took the bike for a quick ride today ,came to a stop light and my idle dropped just below 500 rpms...... where should i look first ? Im scared to go for a long ride then it shuts down and wont start.

 

For what its worth, I had this problem for a couple weeks not too long ago, after I fixed some grounds all the problems went away. Have you noticed a pattern when it cuts out? Next time this happens, recreate the conditions of the failure (same gear/RPM/speed/maybe it only happens when the clutch is in../whatever) and see what happens (preferably not too far from home). When my bike was having similar problems, it was usually when I pulled the clutch in and was decelerating. I noticed that the RPMs would drop to around 500 or a little bit lower and then the engine would die two seconds later.

 

Depending on your year. Mine is an 01. I had similar problems with it. Look into your fuel pressure regulator.

 

i just need it to run til first snow fall, so i can take it apart to get it ready for next season.....but i will look into it.

 

sorry did not notice your comment til now .but i cut out on me once after that only low idle at stop.also i have notice when i warm it up now the idle starts low around 800 then it will climb to 1800 where before it would go straight to 1400 go up to 2000 the would drop til 97 degrees popped up on the cluster. so idk i might take my last rides this weekend then take apart ....
