I have a honda 2011 420 that never had any issues until now. It starts fine an idles fine even when I give it gas. But when I put in in drive to go forward it won't run. It keeps studdering out and wants to kill when I give it gas. But if I put it in reverse it runs perfectly fine with no issues. Can someone please try and help me possible issues?
HI: Your problem could be the fuel filter -- if you haven't change the fuel filter it could be real dirty and your bike is not getting the proper gas flow to run. The fuel filter is in the sub fuel tank -- located in front of the engine left side.
