Hi guys i want to ask for help.Last summer i was cruising around city and the bike just died at stop.Then after riding the bike about 10 15 mins it just starting to lose power and its like have not taking fuel.I changed the fuel also the fuel filter still same then changed the fuel pump and problem was gone.Now when winter is gone i take the bike for a short ride and same problem happen . I noticed that after 11-12rpm i starts to lack of fuel or something like that idk.I came back home and it dies just at the door.Then i started it again and started to make some grouling sounds i rev it up and kinda fixed it but i think the problem will come back again.So is it again the fuel pump i change allready one doesnt have even 500 miles on it since chaning.What else can be ??
P.S sorry for the bad english i am from Bulgaria.
Cheers
