KFX 450R don't start unless give throttle when hot

Recommended Posts

Hi I have a KFX450R 2008 model it has been great but I was riding the other day and I let off the throttle and it just died so I tried to start it back up and it would not start unless I gave it a little throttle and then would die again if I let completely off the throttle?? as soon as the machine cooled it will start fine without any throttle?? Keep in mind this is fuel injected so you shouldn't have to give it any throttle any help would be appreciated thanks.

Have the same problem with my LT-R, mine has a lever that you can throttle up with for warming up, or you can use it like a hot-start for easier starting when the machine is hot. Also, check your owners manual for throttle cable adjustment procedures and specs. You may just need compensate for a slightly stretched cable.
