Hi everyone, I have a 2015 UFORCE 800 that I did a rebuild on. Engine is back in and it starts the first try. howver i notice the front exhaust pipe glows red after about 30-50 seconds. the rear exhaust pipe is ok. I checked the coolant and it seems fine, even pulled the theromast and going without one to make sure the engine is getting good coolant, both coolant lines get warm so that tells me coolant is flwoing through the engine AND iI get a nice swirl of the coolant at the rad fill tube. Can it be a timing issue as I had someone tell me to be careful with timing as it can be tricky. Thought it might be that it is running lean, but i do have the filter air box in place. when I pulled the plugs, they are OK and not fouled. Anyone have any thoughts or had this issues.
TIA
Craig
