this may mean it is too rich, make sure the air filter element is new and change the oil which can get contaminated by fuel. some new spark plugs may help
There is obviously other reasons but start with these simple things.

SOURCE: why is it my xrm 110 is hard starting and uses many spark plugs
To much fuel being put threw the engine.

Hi, I'm a 45 yr Yamaha mechanic & take this advise or not, But if your harness is been stripped open or cut up badly, You definitely need to replace it with new from a Honda dealer. You MUST have the correct year so take the 17 digit serial number with you. It is stamp on the MAIN FRAME somewhere. You can install it, It isn't very hard to do. All the plugs have matching wires & connectors. Just look at the colors of the wires going into & out of a plug. They almost always match up. The very few that don't will have the only matching plug in that section. Then if you come to a plug or wire that you don't know, Any Honda mech. can tell you that exception. Or come back to me at that point. Don't try to wire it without a good harness, You can burn out some expensive parts if not already done.
