A couple of years ago, with 25K on my TLS, the motor went out. I swapped it with the TLR motor and made the few modifications to accommodate. It was fine for a while, but lately it has been running too hot. I installed the manual fan switch, but it doesn't seem to help with the current issue. The fan will come on at 216F, and the bike temp will level off for a few minutes, but then continue to climb until the bike shuts off at around 232F, sometimes a few degrees earlier. I have to increase the choke (fast idle) to keep the bike running because it begins to studder and then dies. The bike won't start up again until a few minutes later, a protection measure I assume. I realize that the TLR motor is usually supplied by two radiators, but I am only using the one stock radiator with my TLS frame and body. I considered installing another fan on the radiator, any thoughts on this? Today, I plan to do a thorough radiator flush, and reset the bikes TPS settings to ensure correct idle. I thought about trying to get a lower degree thermostat? Currently, I am using the TLR thermostat. Also, I plan to add some "water wetter" to assist in keeping low, but operatable temperature. Any recommendations on this? I am not sure what to try at this point so any advise would be greatly appreciated. You guys are always so helpful, thanks again!

Have you considered that the present thermostat might not be working properly?

I got this thermostat new when I did the motor swap a couple of years ago. I am using the TLR motor and thermostat, but the TLS radiator. I will test the thermostat later today when I get it taken down. What about running the bike without a thermostat, I know it's not good long term, but could I do this to see if the temp will still rise and shut the bike down? Thanks!

That's a quick way to determine if it's the thermostat or not, but don't ride it like that for more than a test since you'll be running the cold FI map all the time. :thumbup
