"I brought the bike with the pump on and this is the first time i took it out dont know what else i should tell you about this really"
well at least I know now that you never ran the bike before!
if theres no water in the gearbox
There was water in the 2T tank when you filled it or at least there HAD been at some point, and of course this water filtered down to the pump and just sat there as it had nowhere else to go!
Bleed the pump until clean clear red oil only flows from the bleed,id give it a rinse in something first, diesel oil maybe
and in future it would help that you posted the full details and history in your first post, I assumed that this was a sudden occurance...why wouldnt i?
