I am putting new all balls steering stem bearings in my 2002 VTX1800C. Part 22-1020.
There is a lot of information about how to set the preload on the bearings, but nobody mentions whether having a fairing would affect it. By the manual, it says to set the preload at 1.76-2.64 lbs if my calculations are correct…they show 0.8 – 1.2 kgf. I found that 1 kgf is equal to 2.2 lbs…so I did the math and came up with those numbers. Please feel free to correct me if this is not accurate.
Now, I am assuming that I would want to set the preload a little heavier since I have a fairing. It’s a Woody and has a single DIN deck in it, 4 Polk DB521 speakers, and a Rockford Fosgate amp. Also has a fuse block and relay in there. Of course, lots of wiring too for all that stuff. I haven’t pulled it off the bike yet, but all loaded up…I am guessing it’s in the 40-50 lb range. I derived this number via the rectal extraction method.
So, assuming I am correct and that I should have more preload, my question is…how much?
I should add that I do have cruise control and HID headlight too…not that the ballast and servo would add much weight, but it adds… I am 200 lbs and carry a 150 lb passenger most of the time. I have very large hard bags and pack them full on long trips and also have a hidden hitch on the bike and pull a trailer with it on long trips. Did the Lake Superior Circle Tour last year, 2-up and pulling the trailer. Serious touring rig!
I am guessing that although I have progressive front fork springs, that due to all the added weight of the fairing, I am bottoming out or something because the bike just rides like shat over bumps. I am seriously considering ordering the full RaceTech springs and gold valve system they offer. But, wondered how my fairing weight would affect spring choice there too. Am not great with all the suspension lingo, I just want the best ride possible. I want it to hold the road in aggressive cornering if I hit a bump, but mainly want an awesome ride going 80 mph down the highway. Any of you suspension guys or anybody that has installed the RaceTech stuff...please tell me anything you think I should know.
Not sure if it matters, but I have Progressive Airtail IAS shocks in the back.
Please let me know your thoughts,
