over-heating symtom?

I was riding my 02 Superglide yesterday and enjoying the 85 degree weather until i got stuck in a traffic jam. While inching long (for about 15 minutes) I noticed the bike seemed to be vibrating quite a lot heavier than usual. When the traffic freed up and i was able to cruise again, it smoothed out. Was that an indicator that it was starting to over heat? If yes, is there a point when I should pull over and shut down?

You could experience pinging as a result of overheating in the early stages and possibly rough running in the onset of overheating

Check out this post in the DIY forum and it will explain heat management on your bike.

RE: over-heating symtom?

When I rented an '05 Heritage in Las Wages earlier this year one thing they did tell us renters that if you sit in traffic too long (?) with a twin cam and then engine starts pinging, loping or strugling then it is about to overheat and we should either cut through the traffic or pull over and shut it down for a half hour. As these are rental bikes, I am sure everyone did this....

My Road Glide did the same thing.

I have heard that the TC88B engine runs hot, so you may want to monitor it. Either way there's two solutions (1) oil cooler or (2) fan. Harley sells both of these. I don't have much time on a motorcycle, but my sportster has never gotten hotter than 210 degrees (oil temp guage) and it only reached 210 degrees after 1+ hour in heavy chicago traffic. Correct me if I'm wrong, but you can get away with more heat depending on the type of oil you use. Fossil oil will retain 100% protection up to 250 degrees and synthetics up to 300 degrees.

If the bike has EFI, then as the bike starts to overheat the fuel/air mixture is changed. I remember temps around 310F the first stage kicks in. The manual says the bike will appear to run rough. They run the fuel very lean so that the extra air and less fuel mixture burns cooler. There is another stage that kicks in around 330F where I believe one plug will not fire. You will get some backfires in this mode.

The EFI only does this when idling. Once you give it any throttle it goes back to normal operation.

Don't quote me on this, just going from memory. Everything should be in your manual. They didn't say anything about pulling the bike off the road to cool off in the manual... I think. But it seems like a good idea to do so.
