I have had a really bad wobble on decel since my bike was new in April of 2011. I have had the steering head bearings checked and tightened with the best efforts it did not help. I had two other dealers also check and ride the bike with no improvement.
In two riding seasons a front tire was replaced under warranty with no real improvement at about 16,000 kms (10,000 miles) and a new rear was installed this spring both were the stock Dunlops. I like the ride and the mileage and was satisfied with the rain performance but the head shake was most disturbing.
Last week I had my dealer install a set of the new Michelin Commanders front and rear at about 45,000 kms (27,000 miles) I have long suspected the tires were the issue and hoped the Michelins an approved tire by the MOCO would solve the issue.
I recieved a call from the service department advising me the bike was ready and the violent headshake was gone. To the pleasant surprize of the tech and the manager . To thier credit the dealer had spent a lot of effort trying to resolve my problem. They did contact both Deeley HD the Canadian importer and the MOCO with no advice offered other than the updated service bulletin and to always keep my hands on the bars.
If any of you continue with the head shake maybe replacing both tires will help you. I have not been able to make it shake on decel without actually forcing it so I am happy. I will hopefully get good wear and the new tires will work well in the rain. I hope to get some riding to see how they work,
Thanks for all the contributions to this thread with suggestions from the members. I can now enjoy my RGU without worrying.
Thanks to my dealer for working to resolve my issues and taking good care to try and get to the bottom of this issue,
I would rather be lost on my Harley than found at work,
