Temperature Gauge Problems?

She's up an running like a top!!!

I'm so very happy to be riding again, although I'm taking it easy since it's been so many years since I was last on a bike.

I had a young man change out the mechanical seal (thanks again, Doward!) for me and get her going. Everything seemes to be fine with one exception...

The temp gauge would climb up to the maximum for a few minutes and then come back down to normal, but now it just goes to max after a few minutes of riding (or idling) and stays there. The bike runs fine and I can put my hands on the cylinders and crank case for several seconds so it's not like it's heating up to a meltdown of biblical proportions.

My mechaninc took the thermostat out of the parts bike and tested it before he installed it, and ended up getting an O-ring kit for putting it all back together. I put 42 miles on it without any signs of trouble

Any suggestions?

Thanks guys...I'll give it a try this afternoon!
Well I checked it and got a whopping 0.53 volts so that sounds like it may be the problem. I'll get an infrared sensor on the crankcase and cylinders tomorrow to be sure. I'll also recheck the voltage as it was getting dark and I'd had a belt or two to double check.

It sure is great to be riding again!!!
Even with the temp gauge burried all the way over the cylanders are still only reading 185-195 farenheit so well within normal limits. I check the temp every time I get home and pull into the shop.

The only issue is the left cylander is always about 20-30 degrees cooler...fuel mixture and or carb synch I'm guessing?
Update bump...I picked up the parts bike a few days ago and replaced the 7v reg this afternoon and everything works fine!
