Get ya think caps on boys!
Have had the ST4s up and running for about 2 months now has been running really strong except twice now when i hve been riding i have stopped and started a few times then all of a sudden when i go to start it , it will crank fire then die and just crank over ...the first time i left it for a couple of minutes then tried again no luck , after doing this for 3 -4 times it fired and i just held it wide open reving to about 7thousand and it stayed running.
today though it just would fire so i held it wide open and cranked it for about 40 seconds and she fired.
I pulled the fuel pump out and checked for split fuel hoses but all was good as was the fuel filter....???????????
HELP!
