I didn't think the xc-w had this issue.
The bike is stock except for the acerbis tank and the 14|52 gearing.
The bike is acting like its running a little lean as well.
Is there a better coolant? Seems like the least modifying and least expensive way to go?
flush the oem coolant out with distilled water and put some "engine ice" in there.
