Hi guys
Really need help few weeks ago my cbr 600 f4 started coffing and dieing on the moterway on the way home manged to get it home on back roads low speeds cleaned carbs out made small diff but now its been sat a few weeks it wont start at all now I think its fuel pump what do you guts think ?

 

I would make sure that the gas tank and fuel filter were clean and obstruction free, fresh gas and a full tank. Make sure the Carbs a re sync'ed and the idle is set to 1300 rpms.
