Overheating

I agree with jre258 in SoDak, its now time to move inward and I would be checking first for kinked shut top radiator hose then to stat for backwards or stuck shut next.

Update: Checked overflow hose and bottle, thermostat, water pump, temp sensor and fan switch, and all hoses are new and radiator cap. I'm beginning to think the radiator is not getting the proper flow as the temperature rises slowly but steadily. I have a parts bike and I've had radiator checked so I'm gonna try to change it myself. Never had any fluid on block or engine head. Nothing on ground. Use Engine Ice in radiator. Any suggestions?

Just a thought. You could simply remove the thermostat, run it and see if that makes a difference. That's what I used to do with the cars. It is possible that even a new thermostat can be bad. According to the manual, thermostat should be fully open at 203 Deg F, full valve opening should be more than 8mm. Should start opening at 176 - 183 Deg F. Without a thermometer, one could bring to start of boil in a pan of water on the stove and check opening. If it opens, it probably is good. If it doesn't, there's your problem.

Also, I'd back up, verify that the hoses are all properly connected, that somehow a hose wasn't misrouted.

I'm sure the answer is out there and once you find it, will probably wonder why you didn't see it earlier. I've been there and done that.

Once had a radiator start to get clogged , and I swapped it out with a newer better one from Carl Leo. Cheaper than having the radiator shop deal with it at the time. Just a thought.

Update: Put new radiator in. New Artic radiator fluid from Kawasaki. Rode 300 mile round trip today without any issues. Temp guage never got any where near half way and I didn't get under 85 mph on ride home. Thank you everyone for all the replies and help!

Well that Voyager in good condition. But you do not RIDE so fast

I usually don't ride that fast; but I wanted to take it through the paces to make sure it was really ready. It passed ALL my tests.
