I need some help here. I'm not sure what i have done here but I took the bike for a 400km ride a couple weeks ago and it ran fine, didn't miss a beat. Fast forward to just a few days ago and the bike is getting harder to start cold, now requiring full choke and around 1/4 throttle to get it to fire up and a few seconds held at that position while the revs slowly make it to 1500rpm. When warm the bike almost refuses to move from a stand still and has a noticeable flat spot till around 3000 rpm. The bike had only done around 1300km since its last service, I havent touched anything since the service and have run premium fuel.
