Hi. My name is ***** ***** I would appreciate the opportunity to help with your question.

Expert:  Steve replied 11 months ago.

P0118 = engine temperature sensor high.

your bike has no crank/cam position sensor issues. it only has a crank position sensor.

what did you do with the heads?

in your post you mentioned everything that needed to be done except the heads.

tell me everything you can.

I help people fix their own bike. I do not help mechanics.

if you have a mechanic, I will opt out.

best of luck with your problem.
