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?

It could be the 7 volt but it could be something else.

Place your bike on the centerstand and run it till warm. Then slowly turn the handlebars each way and see if the needle change is because of that.

My brothers bike had a similar problem and every time the bars were turned to the right the gauge pegged and to the left it went back to normal. In the middle if coming back from the right it stayed peg. Using my test light I found that when I had the clamp on the key and light on the headlight bucket it went back to normal. Took it off and it pegged out again.

So look at your wires and grounds.
