Purchased a 2005 YBR to start off on after passing my CBT 2 weeks ago. Late starter, but caught the bug after a free Get On ride. However, my YBR has a problem on starting. It has a manual choke, which I open on starting then reduce down asap. However, if I bring it down too soon it cuts out. Also, if I touch the throttle it can cut out. It can take 5-10 minutes to be warm enough and safe enough to pull off and not risk it cutting out when you have to stop. Any advice greatly appreciated.
