Pull the codes and let us know what comes up.

I ran a check on the dash
Under P the code P0107 came up:
man sensor failed open/low carb
Under S the code U1097 came up:
loss of speedometer serial bath carb
Is this a jetting issue? or is my bike running to lean or rich?
Any advice on what these codes mean will be greatly appretiated. Thank you

Map sensor failed open /low carb.
I have noticed in the last few days when I pull the choke full open it doesnt run normal, half open she runs right.
could this be an indication of a stuck choke cable?
I will remove it and grease it. Im thinkin these two problems are related.
