Hi, I was wondering if you could give me some help please? I have a problem accelerating with my RX If i try to accelerate any harder than very gentle the engine growls and sounds like it has responded but the bike holds back and doesent get any faster as if something is blocked? if i ease the throttle off then it picks up speed gradually and has no problem going 150 odd. i only just bought it and i know it has been sitting unused outside and uncovered for 6 months or more. If you have any idea what it might be, please let me know. Thanks and bye for now, Eddy :-)
