When your bike have past 100k (km) remember to bring with you a spare fuel pump.AND hose-clamp.....
It is a ok job,but you wil be sweaty ,and saying strange words.
U dont get any advice,,.
When trying to start,,several time,,chech the sparking plug,,if it is dry,and no smell of gasoline,,there is no fuel..
Take your hand,fingers, on the fuel-line,turn on the ignition,,you shuld feel that there will be a pressure..if not,the fuel pump is not start.
check that the fuel pump get 12 V.....
