My 2000 cbr 600 f4 sat for 6 months now it will not start. No sound no clicking nothing. Have a new and charged battery on there. Good fuses. Im thinking the solenoid is faulty because when I tried to jump with screw driver it cranks, but doesn´t turn all the way over. Does this mean I need to check the spark plugs? Starter motor? Also when I try to push start the bike, it makes a deep rumbling noise but doesn´t start. Have tried in gears 1-4. Any suggestions helpfully comments?
