Hope someone in here has better knowledge than I. 2006 k1200lt with 71,000 miles. Cooling serviced less than 1000 miles ago and fluid is topped off. It seems to have an intermittent problem. Some days i'll go out and ride all day with stop and go, and no issues. other days (as in today) went out and bike overheated (no red line on the 06, just black band all the way up)and fan never came on. Stoped the bike then turned the key back on. Fan kicked on, but stopped shy of cooling the bike properly. rode it more. stopped let it idle and fan kicked on but stopped again (actually cycled on and off). The bike doesn't act like its overheating, but the bars are way up there. Can anyone give me a starting point for diy troubleshooting. Does the Water temp sensor turn on the fan. Did a lot of research but just can't find exactly what controls the fan. Don't want to spend a bunch of money at the stealer before I exhaust all my options. Any help will be greatly appreciated.
