hi all. please can someone help me with starting a yzf250 on a 2010 when hot. the bike starts no problem from cold but once it has done a few laps and is warm or hot or even when its been stood after a few short bursts of the track it will for the life of me not start again unless you bump start it. not good when you crash out on track and you have to push it back to service area and no matter what you do to it it will not start back up. all help will be much appreciated.
