That's a really good suggestion. I wonder how much they'd knock off the job if I brought them in that way?
My local dealership quoted me 1.5 hours labor plus parts/oil.
Depending on what you are buying the parts for; you need to be careful because the book said I needed 2 sets of the seals at $100 each for a KP but in reality the kit comes with 2 sets so you only need 1 set. You can also buy aftermarket seal kits that don't have the hardware/bushings that hardly ever wear out; just the actual seals.
On the X bikes the book words it differently and the price is significantly lower. Why, I don't know, because they are the same forks on the KP and X bikes. Could be because I was buying for an 04 KP and the newer ones have upgraded kits or something.
Basically it would have cost me $300 to let the shop do it if I brought the forks in. Subtract $50 for an X bike.
I elected to learn how to do it myself, buy the tools, found the seal kits from Victory for a discounted price of $75, and using Amsoil 5 wt (takes a little over a quart so you have to buy 2 quarts) at $50 for 2 quarts delivered. Cost: about $275.
I am a few bucks ahead on the first fork oil change but the next one will only cost me about $100 if I use the Vic parts plus 1 quart of oil since I still have plenty left and about $50 if I use aftermarket seals.
It's easy to see the long term savings once the tools are paid for and they pay for themselves on the first use. It's not rocket surgery. The book lays it out well. The first time is always a little time consuming but after that it goes quickly. I know because I put a seal in upside down on my first try and had to go back in to fix it. Went way quicker the 2nd time after I got done being mad at myself for putting it in upside down.
