07 CBR1000 hard starting all the sudden
Hi i have an 07 cbr1000 bought it this year at 10 000km now have a little over 11 000 on it ive had no issues with it until recently. I went for about a hour ride 2 hours there on gad light filled up at a gas station with premium at a premium only pump which the worker recomended so i got all premium and no regular. And since i got back from that ride it has been hard starting aftering sitting for over an hour runs and idles fine. I have since filled up at my usual shell gas station and just recentlg put some sea foam in the tank thinking maybe i out bad gas in or got water or something in the tank.Any other thoughts?
Thanks in advance
