My Message to KAW
Text of my letter to KAW USA:
The Vulcan 750 is a great bike, however in our-online group of VN750/700 owners we have noted a QC issue we need to call to your attention. A number of us have noted that the final drive splines are under-lubricated at the factory. In some instances, this has led to early failure of the final drive. Several riders have checked prior to the scheduled 6000 mile maintenance and have found the splines dusty dry, with early signs of grinding and extra wear. This problem has been particularly noted in 2003 models.
The problem is exacerbated by dealers who apparently don't know to or simply neglect to lube the splines properly at the 6000 mile maintenance. I have spoken with at least a dozen fellow members (out of a membership of 1200) who reported that their dealer either professed ignorance of the need to lube, or flat out stated they didn't routinely do it (even though the manual is clear it is needed). In my case, the worst happened. I had my bike serviced by Forsyth Motosports in Winston-Salem NC, specifically calling attention to the factory list of maintenance to be performed. They assured me they would do all of it. However when the final drive failed some 3000 miles later, they admitted that that "never" pulled the rear wheel and lubed the rear spline at the 6K mile maintenance.
Some dealer education may be warranted, in addition to addressing possible QC issues on new bikes.
