What's the Secret to Riding in Stop and Go Traffic???
Actually I know the answer.... "Don't Ride in Stop and Go Traffic... the K1600 Doesn't Play Well with Others in That Environment"!!!
Just returned from my first adventure with my '19 GT Sport. With about a thousand miles on the bike, a friend (riding an '18 Goldwing Tour) and I spent six days enjoying much cooler temperatures in the area in and around Winter Park, CO.
You get to learn a lot about your new bike when you put 2,800 miles on your machine in six days...
No problems with the GT until I was about an hour away from our destination in Winter Park. We hit some heavy traffic headed for Denver on a Sunday afternoon approaching the Eisenhower Tunnel eastbound on I-70. As we crawled in first gear up the 6% grade for about three miles (twenty minutes), I noticed my coolant temperature began rising from its customary "5 bars" to 6 and 7 (when the cooling fan initiated). Instead of lowering the coolant temperature, I found myself watching my bars rise to 8, 9, and 10 in rapid succession and then saw the red warning light come on......... quickly got over to the right shoulder, turned the bike off, and let it cool for 45 minutes.
Meanwhile, I saw many other brands have no issues with the slow trek up the grade toward the tunnel...
Finally decided that if I could get to the crest of the hill (still a mile or more away), the motor would cool itself down on the descent. While I thought about lane-splitting, decided the best chance of avoiding being stranded on the side of the road was to see if I could get up the last 1.5 miles without putting a lot of load on the engine.
With the bike cooled down... coolant level was well above the minimum level in the overflow container, I decided to make a run for it up the right shoulder. Was able to get into second gear and avoid other stranded motorists and lots of other obstacles on the ascent. As luck would have it, got up the remainder of the grade without further incident.
I did, however, see "2 other bikes" having similar problems..... a new K1600B and an older abandoned K1600 GT..... WHAT GIVES WITH THE K BIKES' COOLING SYSTEM???
I was very conscious of this issue the rest of the trip. While I had no other overheating issues, I did notice that several times during the slow ride through Rocky Mountain National Park the coolant level did rise to 7 bars, but came back down to 5 bars after the cooling fan did its job. The key appears to be that the bike doesn't like to be ridden under much load at slow speeds.
Will definitely discuss with my dealer tech the next time I'm in for service. Appreciate any thoughts from "this learned community"...
Must insert that 80K miles on two FJRs and never a hint of an overheat in lots of slow speed situations.
