Since my bike is part of this, I think I'll pay to have the dealer lube the splines at the time. That way the drive shaft tube will be open to clean out any shavings. It's probably more expensive to have it done this way, but I'll have the valve installed, splines lubed and any potential shavings removed.If your dealer wants to charge you $150 to lube the drive shaft splines, pay up or just do it yourself, but get it done.
