Just replaced the fuel regulator which was blocked & leaking out the back. New fuel filter, pressure is good almost 3 bar, injectors are spraying fuel evenly, new spark plugs. will not start with choke on. hard to start but it will run until you turn the throttle at all, then it stalls. Runs very slowly for about 2 minutes then dies if you don't touch the throttle. Adjusting throttle body screws does nothing. Can't figure it out?? Bike had been sitting for 1/2 a year because of fuel leak. Thanks
